It can be installed open and used as a friction device with pulley or biner in the desired length. It can also be installed in choking mode and continuously adjusted as well. Because of the tube shaped ring, this procedure works much better than with any other tool for this application. The one-and-only combination system of tube shaped ring, parallel sewn 8 mm polyamide rope, as well as segment stitching, makes for a strong, versatile and easyto-use tool in everyday work situations. If you want to secure or block the choked sling, you just need to install a small biner into an open rope segment right in front of the ring. Climbing ropes can be fastened as lower anchors. Find the right arborist rope! When it comes to professional tree climbing rope, look no further than SHERRILLtree. Poison Ivy, Lava, XTC and more – all the ones you need. What’s Online?

J grand canyon President’s Message Linda Hawkins RESPECT: Earn it, Give it & Enjoy it. You either have it or you don’t. You either earn it or you continue to work or play hard to gain it. The list of people I respect increases on a regular basis. As an avid outdoor enthusiast in both work and play, Mother Nature tops the list for the curveballs she sends and the environments she creates. I am planning to see one of her most spectacular creations next year when I go paddling in the Grand Canyon. And as we all just worked through record-breaking temperatures this month, which brought with it fantastic storms, Mother Nature continues to keep us on our toes. I respect people who continue to improve their level of knowledge through attending classes or through online courses and the fact that they find time to work this into their busy lives to gain the designation they desire. I respect those who have become Board Certified Master Arborists, as it is a tough test that I will try again to pass this fall. And I respect those who take that knowledge and are able to share it with others and enjoy doing it. These individuals can speak in front of large groups and put their knowledge in a format that keeps our attention and inspires us to work smarter. I love to read and as I write this article on a regular basis, I respect those people who write easily and articulate exactly what you need to know without losing the point by going on and on. I learn to write better everyday, right Ken?! Earlier this month, I was asked to inspect some boxwoods on balconies in Toronto. As I entered these spectacular condominiums, I was awestruck by the views of the city and the richness that surrounded me. It never ceases to amaze me how the other half live and I always wonder what they do for a living and how they came to be able to live in such opulence. Were they just lucky or did they gain the respect of their peers and the knowledge that enabled them to choose a course that afforded them a life of what I consider to be luxury? Fortunately these people also choose to hire professionals to care for their homes and gardens and that often includes arborists. So I respect the clients out there who hire arborists to do their tree work because they respect what we can do for them. Respect also goes the other way. I do not respect people who speak ill of others regardless if they work for or with you or for another company, or don’t do things the way you would. I am talking about arriving on a site where someone has done work before you and it is different than the way you would do it – not necessarily wrong, just different. With this attitude tends to come laying blame or not accepting blame for something you did. Respect for elders has been ingrained in us since we were children. Respect for other drivers (don’t forget to merge and always signal) helps us on the road daily. Respect for professionals such as athletes, scientists, doctors and even lawyers (don’t comment!) tends to typically be granted. And I know we all respect people who conquer challenges in their lives such as debilitating injuries or illnesses and the people who help them do this. Finally, from one arborist to another, I respect the career path you chose, that you make this organization a part of your lives, and the fact that you care for one of Mother Nature greatest creations, TREES. In the words of the Staple Singers, RESPECT YOURSELF. J CORRECTION 2012 May/June Issue fleming climbing champ In the May/June’s President’s Message, it was published that Matt Howard was the climbing champion at Fleming College.

ISA has also arranged for a variety of tours from wine tasting to Multnomah Falls and Mt. Hood. multnomah falls near portland, oregon International News Alastair Fyfe, ISAO Representative Gearing Up For Portland, Aug. 11-15 It sure has been a busy year to date! International business has been interesting to say the least. I was quite taken aback to hear that Arboriculture Australia (AA) has lost their status as a Chapter; effectively, they have had their Charter withdrawn and are out of ISA. U ntil a replacement organization is located in Australia or International comes to an agreement with AA, the International office in Illinois will service individual members. I am not speaking out of school to mention this; ISA has been quite open about the event, the steps taken to resolve the issues and the policies in place to service existing members. The only reason I mention it here is that it will no doubt make for lively discussion at the Portland meeting. Many Ontario arborists know several of the Australian members personally and it is quite a dramatic turn of events, the intimate details of which are known only to the Board and no doubt they had cause. Should you like to know more about the situation, a detailed exchange of cor- respondence is in the public domain on Arboriculture Australia’s website which can be found easily on search engines. And I promise to report further developments, if any, after the meeting in Portland where all Chapter Representatives will meet with the Board. It is a situation that will hopefully be resolved sooner rather than later and in a way that all parties can move forward in an amicable manner. When joining the Council of Representatives (or more accurately, extending my term with them) I was pleased that Craig Hallam from Australia was the Chair as while he is very direct, I have always viewed him as a “get the job done” kind of guy. With Arboriculture Australia out of the picture, they no longer have a seat on the Council so we lost Craig. John Gie- draitis from Texas, another hard working “get it done” guy has stepped up to the plate and has jumped right in where Craig left off. In actual fact, the entire Council is full of people like this, which makes it a pleasure to be associated with them. Speaking of the Portland Conference, there is still time to register for this great event. The venue and speaker line up are excellent and can be viewed online at isa-arbor.com. The Ontario Chapter will have a booth there promoting the 2013 Toronto Conference. If you are attending in Portland, please contact Paul Kobold to Ahead in this issue... just the facts!

More than a century later, the chestnut returns to New York. Despite fears of budget cuts, both CFIA and NRCan are operating business as usual. We said good-bye to Erik Jorgensen this spring, one of the first urban foresters (who would have been happy to read about saving a 100+ year-old pine in Midland). American Chestnut Returns to The Bronx In 1904, chestnut blight was discovered at the Bronx Zoo in New York. At that time, chestnut (Castanea dentate) represented about one quarter of the eastern forest’s hardwood. Four billion trees died. Today, chestnut is an endangered species. Using a gene extracted from wheat, scientists raised chestnuts that are resistant to blight. The gene detoxifies the oxalic acid produced by the pathogen. In most chestnut, oxalic acid attacks the cambium, a canker forms, and everything above the canker dies. In the transgenic trees, the oxalic acid is detoxified and the tree is not damaged. Ten of these designer trees were planted on April 18 at the New York Botanical Gardens, just a stones throw away from the first discovery site of the disease. The trees are among 470 that being tested in other sites. — Pat Kerr More: http://conted.nybg.org:8080/WebModule/jsp/ed2df.jsp?df1=slayout:124HRT400&df7=06x And: www.sciencedaily.com/releases/2012/04/120412141816.htm And: http://articles.nydailynews.com/2012-04-20/news/31375903_1_blight-resistent-trees-chestnuttree-american-chestnut-association And: www.syracuse.com/news/index.ssf/2012/04/esf_professors_send_improved_a.html 8 • www.isaontario.com small photo: american chestnut, karren wcisel, www. treetopics.com CFIA Invasive Surveys Continue The Canadian Food Inspection Agency (CFIA) is planning similar numbers and patterns of trapping and surveys for emerald ash borer and Asian long horned beetle in 2012 as was done in 2011 explained CFIA’s Brian Hamilton. Last year, 591 traps plus surveys were completed in Ontario. This year, 525 are scheduled but the agency will also respond to “call-outs” and expect this number to increase to last year’s level or higher. Since we have no effective trap for ALHB at this time, ground surveys will continue on a grid pattern both within the regulated areas and throughout Ontario and Quebec. The list of cities to be targeted in 2012 is not finalized but they plan on 510 sites. If no further finds are discovered, the Vaughan site could be declared eradicated next summer. Hamilton concluded, “No regulated system is 100%.” However, we are monitoring at the border and watching — Pat Kerr high-risk areas. NRCan Invasive Species Cuts a Myth Although there are many rumours circulating to the contrary, Jackie Perras with Natural Resources Canada said, “Following Budget 2012, Natural Resources Canada (NRCan) has maintained funding for both staff and research for work on forest invasive alien species. NRCan continues to make significant investments in forest science, in innovation, and in transforming — Pat Kerr the forest sector.” Fight to Save a Single Tree Pays Off! Influential Forester Erik Jorgensen Passed Away This May Erik Jorgensen, the first urban forester, passed away May 25, 2012, in Guelph. He was born October 28, 1921 in Haderslev, Denmark. At the invitation of the federal Department of Agriculture, Erik, his wife Gitte, and their two daughters, immigrated to Canada in 1955 where he pursued a long, passionate and distinguished career as a forest pathologist. At the University of Toronto, Shade Tree Research Laboratory, his team discovered the first cure for Dutch Elm Disease. At the Ottawa Forest Management Institute, Erik created a national urban forestry program. At the University of Guelph, he was director of the Arboretum. During his life in Canada, Erik made many dear friends and inspired numerous future foresters. He authored over 60 articles and scientific papers on tree diseases and urban forestry; founded the Ontario Shade Tree Council, and was a life member of the Ontario Professional Foresters Association and a fellow of the Canadian Institute of Forestry. He always advocated the planting of native species to regenerate Canada’s natural heritage. Erik was predeceased in April 2012 by his loving wife of 66 years, Gitte. He will be greatly missed and fondly remembered by his daughters Marianne La Rose and Birthe Jorgensen, son-in-laws Bob La Rose and David Baker, grandchildren Karen Irvine, Jenn Wagar, Zeke and Stoney Baker, grand-son-in-laws Howie Irvine and Andrew Wagar, and great grandchildren Mackenzie and Penelope Wagar and Warner and Jackson Irvine. The family held a private interment for both parents in Puslinch. Donations in Erik’s memory can be made to the Ontario Forestry Association, www.oforest.ca. In response, Pro Oil Change voluntarily agreed to reroute their driveway and allow the tree’s root zone to remain undisturbed. When the tree dies of natural causes, Pro Oil will be allowed to construct their driveway according to the original plan. Company Changes Development Plans to Save 180 Year-Old Pine “It’s an elegant compromise,” said councillor Pat File of Midland, Ontario. Pro Oil Change proposed a new franchise to open at King St. and Colbourne in the small town located on the shores of Georgian Bay. Slated as part of the development, a white pine estimated to be 180 years old and growing on town land was to be removed for a driveway. The town agreed to the proposal, but the community didn’t, and there was an outpouring of support for the tree. Travis Allan, President of Pro Oil Change said, “We have made some serious concessions to our site plan and the configuration of our operations purely for the benefit of the tree. Our wish is to keep nature where it is and alleviate the concerns of Midland residents.” Charles Dyer, landowner and developer said, “We have agreed not to build the entrance to Colborne Street in order to save the white pine tree. If the town removes the tree in the future, then we reserve the right to build the entrance. This is a fairly major concession as it restricts the flow of traffic on a fairly tight site.” Pat File is delighted with the turn of events. After six years in the community and many failed attempts advocating for the protection of trees, she feels everyone wins with this decision. In addition, at Monday’s council meeting, a citizen coincidently presented a paper on trees. After hearing both reports, council voted unanimously to investigate the potential for a tree protection bylaw and a heritage tree program. — Pat Kerr More: www.midlandfreepress.com/ArticleDisplay.aspx?e=3564141 And: www.simcoe.com/news/article/1351939--will-town-go-out-on-a-limb-for-majestic-white-pine Come across an interesting news item?

Heat Islands Can Benefit Trees We all know the many ways that cities make life harder for trees, but Science Daily reported in April 2012 that the heat island affect can also benefit trees. One of the main factors considered was that the increased city temperatures at night allowed for an increase of up to eight times the growth of comparative trees grown in a rural setting. The trees reviewed were park, not street trees. The study, published in Tree Physiology, said, “Overall, our findings indicating greater seedling growth and establishment at a critical regeneration phase of forest development may have important implications for the ecology of urban forests as well as the predicted growth of the terrestrial biosphere in temperate regions in response to climate change.” — Pat Kerr More: www.sciencedaily.com/releases/ 2012/04/120424154341.htm And: http://treephys.oxfordjournals.org/ content/32/4.toc See abstract: Stephanie Y.

Ontario Arborist (July/August 2012) • 9 negligence claim unfounded in quebec Supreme Court Ruled Dispute With Insurance Company Instead Following up on a news item we first published in the March/April issue, the Montreal Gazette reported this week, “The Supreme Court of Canada has ruled that the City of Westmount cannot be sued for negligence in the death of a 27-year-old man who was fatally crushed as he drove his car through the municipality in Summer 2006.” W estmount vs. Rossy. In August 2006, a 100-year-old poplar that afterward was found to be 90% rotten, fell on a vehicle during a windstorm, killing the occupant. In the three weeks following the incident, 13 other trees were found in the same district that posed either a small or medium risk. They were removed. The family of the victim sued the city for negligence. The case was predicted to have farreaching implications on how the autoinsurance board deals with accidents that are not really car accidents at all. André Legrand, Senior Partner with Norton Rose Canada, council for the City of Westmount said, “We prefer not to get into this. A related case is still pending.” Julius Grey, counsel for the Rossy family, said in a telephone interview from Montreal, “I still believe the judgment is incorrect but the Supreme Court is the law in our land. We need to start a debate about the purpose of no-fault insurance. We have two forms of no-fault insurance: worker’s compensation and auto. These are both important. Certain accidents are seen as a risk in our society and not tied to moral fault.” Grey explained that in this case the court did not hear the description of the tree and he believes there was moral fault. An expert was willing to testify the tree was perilous and it should have been cut years before. It was an accident waiting to happen. It could have fallen on a pedestrian or a cyclist and then the no-fault auto insurance would not have been an issue. “There is little purpose to putting this accident on the social scheme.” (But by relegating it to the social no-fault auto insurance arena, it did severely limit the amount of the claim.) The town was not involved. The dispute was with the insurance company. Grey would not comment on whether the city has changed its tree care guidelines in response to this “incident.” — Pat Kerr More: www.globalnews.ca/supreme+court +of+canada+to+rule+on+montreal+fallingtree+fatality/6442666581/story.html And: www.montrealgazette.com/business/ Westmount+sued+tree+that+struck+killed+court/ 6824861/story.html Complete Insurance for Arborists ArborGuard provides customized, yet flexible, insurance coverage at market leading premiums.

Ontario Arborist (July/August 2012) • 11 What’s Bugging Your Trees? Jen Llewellyn, OMAFRA Plant Health in the HEAT: Water Those Trees! As I write this month’s column, the high forecasted for today is 33o C and the humidex rating is over 42o C. I don’t have air conditioning at home and I am seriously considering sleeping on the floor of my office tonight. We have had a tremendous amount of heat since very early spring and you have probably noticed that plant and insect development is 2-3 weeks in advance of normal. On top of that, there has been a serious lack of rainfall in several key agricultural areas of southern Ontario. M any of the southern Ontario conservation authorities declared a Level I Low Water Response in their watersheds back in May (in May!). I’ve never seen anything like it. Some of these watersheds are very close to declaring a Level II. The average precipitation across the Hamilton Conservation Authority watershed was between 40-60% of normal for this past spring. So to get on topic, if you think that poor little tree doesn’t deserve some irrigation, think again! Most newly planted trees require irrigation, especially in the first year or two of planting. They have a very small root 12 • www.isaontario.com system and the water use demands of the canopy will not be met without a little help from us. It’s been extremely dry since early spring, which means that our soils don’t have the moisture reserves they normally would coming into the summer season. When soils are this dry, it takes a long time to wet them again. Irrigation water will actually bead off dry soils and mulch. That’s where a long, slow, deep soak using low volume and low pressure comes in. This slow delivery of water will be required for the moisture to actually make it down into the root zone. This can be achieved by slowly applying an inch or so of water to the soil every 7-10 days during hot, dry conditions. Researchers at Michigan State University came up with the following chart: crown Spread (M) water required (L) 2 75 2.5 115 3 190 3.5 265 5 475 6 750 Many homeowners have automated irrigation systems installed in an effort to reduce the stress on their landscape plants. In most cases, the irrigation systems have been designed to deliver water efficiently to the root zone and can be deployed after sunrise to facilitate leaf drying by midmorning. Any time we spray water on leaves, those leaves can stay wet for hours and that period of time is called the “leaf wetness period.” There are several different kinds of fungi that can infect leaves after only a 6-8 hour leaf wetness period, is, the challenge is to educate the client without insulting them. Sprinkler-type emitters are still very popular as they can deliver large amounts of water over large areas. Unfortunately, they are not very efficient because a significant percentage of the water droplets can be lost to wind and evaporation before they even hit the ground. In some cases, low volume irrigation (e.g. drip) systems can be an effective alternative to deliver water much more efficiently to the root zone while keeping water off of the leaves. gardens and lawn looking great. This spring they planted a B&B Colorado spruce out front. They said it took about 8 hours with a pickaxe but they finally dug the hole! I realized that the tree never actually leafed out this spring and this week I noticed that telltale, dull grey hue that spruce get when they are on their way out of this world. It was time to tell them – and they weren’t happy. What happened to the tree? I think if you’ve been reading my columns all these years, you should be able to have some pretty good guesses lined up! J Anything you can do to design the irrigation system and the landscape to minimize leaf wetness periods may result in a much healthier, cleaner looking canopy. some 8-12 hours. If overhead irrigation is used in the evening, you can imagine how easy it would be to create ideal conditions for disease. Recently I had an arborist come to me with disease issues on several different species of plants on one client’s property. Now it’s been hot and dry, how is this possible? As it turned out, they had an automatic irrigation system and they really liked to use it. When asked how often they irrigated, the arborist said: “Well they used to irrigate every day but now they’ve backed it off to every other day.” I actually hear this lot (and continue to find it quite surprising considering the amount of public education on water conservation). So now that we know what the problem Anything you can do to design the system and landscape to minimize leaf wetness periods may result in a much healthier, cleaner looking canopy. I have seen this principle employed very successfully in nursery production. Several times I have had growers tell me that their disease issue goes away after they switch the irrigation cycle to deploy after sunrise (and completely avoid irrigation at other times of the day).

Ontario Arborist (July/August 2012) • 13 in the field with matt logan Education is The Key For Preventing & Treating MSDs As summer and the busy season is upon us, I will discuss issues and injuries that can arise from the constant stress and strain of working in the arboriculture industry as well as some proactive ways to reduce and alleviate these issues. Although it isn’t uncommon for climbers and arborists to have their fair share of bumps and bruises, there is now an upsurge in awareness regarding injuries and conditions that can compound and build over time. The blanket term for these injuries is work-related musculoskeletal disorders or MSDs. T he following explanation of MSDs and their causes comes from www. corergonomicsolutions.com, a certified ergonomic assessment specialist company created and owned by Ed Carpenter, the inventor of Buckingham’s Ergovation saddle. Ed graciously let me use his website and knowledge when crafting this article. 14 • www.isaontario.com MSDs are disorders that occur from repetitive micro trauma or injury to the soft tissues in the body such as ligaments, tendons, nerves, joints, cartilage or discs in the spine. MSDs generally occur from repetitive movements associated with work tasks; therefore they are also called repetitive stress disorders or cumulative trauma disorders. Examples of MSDs are carpal tunnel syndrome, epicondylitis, shoulder impingement, rotator cuff syndromes, sciatica, sprains/ strains and herniated discs in the spine. MSDs can be caused by a number of factors, including: repetitive movement, forceful exertions, awkward posture, contact stresses and vibrations and extreme temperature. When looking at the causal agents for these disorders, it is easy to see why climbers can experience one or more MSDs throughout their career. However Ryan Freeburn, a registered physiotherapist at FreeFlo physiotherapy in Lakefield, Ontario, explains that the issue of MSDs are no more prevalent in our industry than others. Freeburn explains, “Anyone doing a job that includes repetitive motion is at risk. This can include someone working on a keyboard behind a desk as well as a climber pulling him or herself up a tree. The key is how we deal with these issues.” Freeburn puts it simply. In order to eliminate or reduce the effects of MSDs you must: Prevent. As the saying goes, an ounce of prevention is better than a pound of cure. Freeburn explains that simple changes in your daily routine can make a huge difference in the long term. “Proper posture is a good start. Try to stand and sit properly and not slouch. Be aware of your posture and try to keep your back straight and aligned.” Slouching can be compounded by another issue common to climbers – muscle imbalance. This occurs by over-exerting one group of muscles and not having the opposing muscles as strong or toned. This can create tightness, inflammation and pinched nerves. This is one issue Freeburn has been treating me for – my pectorals are constantly tight and in turn pull my shoulders forward pinching the nerves in my arms. By stretching and strengthening my back, the muscle imbalance will neutralize. Another tip: make sure to stretch before, during and after physical activity. Recognize Warning Signs. Listen to your body. If you are experiencing sharp pains, soreness, loss of strength or circulation, consider stopping what you’re doing or at minimum, modifying your technique to decrease strain. When you feel tightness and discomfort, stretch, stay hydrated and when at all possible, rest. Rest. Speaking of which, bodies need to rest to heal. As a business owner and production climber, I know all too well that there is no rest till winter but this type of stubbornness and short sightedness can compromise your long and short term health as well as your safety and production. Treatment. There are many avenues of treatment depending on your particular MSD. It’s important to remember that there are no quick fixes – treatment is a process requiring time and dedication. Adjacent Top. Ryan Freeburn of FreeFlo Physiotherapy applies ultra sound treatment to my elbow. Adjacent Bottom. Arm braces like the black one showing here can alleviate strain and discomfort while you are working. This Page: Freeburn demonstrates effective stretching for your lower arm. From my own experience, it is all too easy to think you’re fixed and quit receiving treatment only to have the same issue return down the road. “Education is key; you need to know what is happening to your body to understand why certain treatments and exercises are prescribed,” adds Freeburn. Ontario Arborist (July/August 2012) • 15 These Treatments Can Include: Deep Friction Massage Therapy. This is a high-pressure massage aimed at increasing blood flow to damaged areas as well as aligning damaged tissues for proper healing. Ultrasound. Sound wave energy is focused on damaged areas to enhance cellular activity and accelerate healing. IFC. Small electric pulses create muscle spasms surrounding the damaged area. This is used to block pain as it distracts the nerves surrounding the damaged area. Arm Brace (tennis elbow brace). Although not an actual treatment, the arm brace works to temporarily reduce strain on the tendon attaching the muscle in your forearm to your elbow. Freeburn explains how it works: “Imagine an elastic band placed around a nail hammered to a piece of wood. The nail is your tendon and the elastic your muscle. When you stretch the elastic, there is equal tension throughout the band and therefore the nail. Now, if you were to put your finger down with pressure on the elastic against the wood and then pull, there would be reduced strain on the nail. That’s what the arm band does; it puts pressure on the muscle to relieve pressure on the tendon.” Freeburn continues, “It is important to remember that the brace just helps to unload the stress on the damaged area and in turn, allows the body to repair itself. In essence, it is allowing your body to rest the damaged area. A very good friend used to remind me: This job is a physical one, use your body but don’t abuse it, there is life beyond work.” In my youth, I was foolish enough not to heed that advice and am now, like many in our industry, having to deal with the results. On the bright side, Freeburn sheds some light, “Most of these issues are temporary and they are reversible. If people use preventative measures, recognize the warning signs, rest when needed, and receive and dedicate themselves to treatment, it is possible to prevent and reduce workplace MSDs.” Have a safe, productive and healthy summer season.

Article by Jon Arnold. New projects don’t often arise in arboriculture; techniques change, but the end results remain the same. In 2011, Shady Lane Expert Tree Care had the opportunity to do something new – bare root transplant large trees at Nathan Phillips Square in Toronto. The scope of the project was complicated. Here were our tasks: 1) relocate 15 trees (bare root) from within the park setting to a temporary hoarding zone before any negative impact was incurred via construction; 2) hold these trees in a pea gravel medium for 18 months using water and compost tea to keep them healthy; and 3) replant the trees using silva cells to maximize the newly developed root size. Editor’s Note: Jon first presented this project at our February Conference in Kingston. Step 1: Accessing & Protecting the Roots The first step in the process was to remove the sod over the existing drip zone so that we could save the root mass. Next, we used an air knife to create a perimeter 1 foot deep and 6–8 inches wide (see above photo). This allowed us to ensure that no major roots were lost in the transplanting and to make a clean cut on larger roots to help prevent further desiccation. Ontario Arborist (July/August 2012) • 17 18 • www.isaontario.com for the winter to avoid frost damage. We removed the mulch at the beginning of the spring to avoid cooking the roots. Originally, landscape fabric was applied to bottom of the pea gravel planting bed to stop the roots from travelling into the soil below. This proved to be inadequate so a much thicker material should be used in the future. Be sure to use a porous material that allows water to filter through so that you don’t create a drainage issue. The trees were in the pea gravel for 18 months, which was more than enough time to create good root growth (though the optimum length would be one full growing season). Step 2: Moving the Trees to Their New, Temporary Environment We used a skid steer to move the trees to the temporary hoarding zone. Before placing the trees in the pea gravel, we used our compost tea truck to add a rooting gel to the entire root system. This helped the roots to stay moist and added mycorrhiza. We quickly learned that the pea gravel held more water than originally thought, so we reduced the watering schedule to one hour per week. We also added 1 foot of mulch Step 3: Returning Them Home When we were ready to replant the trees, we used a larger air knife with a larger compressor to move the pea gravel to allow us to lift the trees. We used our 100 ft, 30-ton crane to move the trees to their new planting sites with ease (see main photo on page 17). All trees went into new soil with Adjacent Page. Note the abundance of new root growth following a winter spent in the temporary hoarding zone. This Page Top. Tree being removed from its original site following root pig-tailing (shown in smaller pic below). This Page Below: Temporary hoarding zone covered with pea gravel. Once we established the root zone for moving the tree, we dug a larger trench around the perimeter. This allowed us to blow down and in to the trench to continuously move soil out the trench with the skid steer. We uncovered all the roots and pig-tailed or braided them to help minimize damage during transportation and retain moisture. As the roots were braided and tied to the trunk, we were able to move the trench toward the apex of the tree allowing us to continue to blow air down into a newly cleared trench. Keeping the roots moist throughout the process was a constant battle; we misted the roots every 20 minutes. Once the soil was removed from the majority of the root plate, we used a crane or large skid steer to break the taproot. Then we wrapped the attachment points in burlap and foam to avoid damage to the bark and/or cambium.

We planted the trees proud to allow for settling of the bare root system. Also, a heavy watering was applied to allow soil settle around the lower root system. Parting Comments & Lessons Learned This was a very innovative project with the potential to improve tree defects underground, soil and growing conditions, and move trees out of urban construction sites to be replanted after construction is complete. Although we didn’t plant these trees within silva cells due to budgetary restraints, the relocated trees were planted throughout Nathan Phillips Square in raised planters or in existing green space. Due to the improved size of the root systems, I believe that all trees replanted will be successful for years to come. Our overall success rate was 79% and we learned a lot about holding trees in pea gravel and the specific site requirements for success. Three oak trees did not survive the overwintering time in pea gravel. Possible reasons include overwatering, the fact that they were in full leaf when they were moved due to the early spring, and they were placed in full shade in the temporary hoarding zone. There are pros and cons to the method we employed here versus conventional tree spading. Bare root transplanting requires four to five people on site, several pieces of equipment, and long days. The pros are Top. Author Jon Arnold on site, Nathan Phillips Square, Toronto. Small Photo. Happy trees in their new setting. that you can retrieve about 90% of the root mass, repair structural flaws within the root system such as girdled roots, and improve compacted or nutrient deficient soils. Another positive of this project in particular was the increased root size due to holding the trees in pea gravel. This is not possible with conventional tree spades. However, tree spades are quicker, less expensive, and have a smaller carbon footprint. This project was a great learning experience for Shady Lane Expert Tree Care and we are very pleased with the outcome. As arborists, we are often hired to remove healthy trees from construction sites in urban areas.

The emerald ash borer also responded to the warmth. Timing for administration of treatments could be three weeks early this year. Check your local conditions to make sure your timing is right. Alternative Species CFIA recommend the following alternatives to ash: maples (silver, sugar, red), hackberry, honey locust, black walnut, eastern red cedar, tulip tree, oaks (swamp, white, burr, pin, red) and basswood.

Note we ran an article on this in the March/ April issue. Treatment Options It is now an established fact: Urban ash in regulated areas will die if not treated. The only possible exception is blue ash. Blue ash are hanging on longer but there is no proof they are resistant to EAB. There are some surviving ash trees in rural areas of the US but these are rare. In urban areas, if you want an ash to survive, it must be treated. Canada has three injection treatment options available. Their success rates and prices vary. Read the labels carefully. These products do not have equivalent tree survival ratings. More data is expected in the fall of 2012 on survival rates but remember, no treatment is not an option; you will lose canopy trees.

The town further reached out to Oakville’s business improvement group to find funding for treating healthy city trees under 20 cm. Once they reach 20 cm in diameter, the town will pay for treatment. The Town of Oakville also contacted the Chamber of Commerce and received their member support for treatment of businessowned trees. Creative Options for Homeowners or Municipalities Pre-invasion. Underplant with a “safe” species and prune healthy ash street trees to avoid the bare look that is coming if treatment is not done. Post-invasion. 1) Use rural forestry techniques to control costs while clearing ash dominated areas. 2) Use the ash wood. Consider garden accent pieces or art.

More information on carvers is expected to be available in this summer at www.backyardstuff.net/aspx/m/846713. 3) Another option is to have the wood dried and milled for any use. Check your local paper, or www.ont-woodlot-assoc.org/ woodlot.html, for listings of portable or other sawmills (and see Dave Boyt’s article in the last issue). Moving Forward Stay positive. The following sites are American in origin, but this does not imply that Canadian scientists are not actively involved in the treatment for EAB. We just lack really good, up-to-date websites. In the ten years since the discovery of EAB, extensive gains have been made. Traps and a pheromone lure are improving.

This spring, one of the discussion topics on the Canadian Urban Forest Network’s electronic discussion forum (CANUFNET) was titled simply: “The Tree of Heaven.” This title gave no hint of the diversity, or breadth, of the discussion. The two main issues that surfaced were planting with environmental consequences and planting for medical reasons. Other threads also popped up including arborists are “lazy” when they recommend non-native species. For those of you who missed it (or those who would appreciate a summary), here is an outline of what transpired online and some expert opinions shared by those who are not always planting in paradise! The Sneeze Fest It was suggested that the Tree of Heaven could be used for those who suffer from seasonal allergies. More correctly termed “allergic rhinitis,” the University of Maryland defines this as “an allergic reaction that happens when your immune system overreacts to substances that you have inhaled, such as pollen.” Tree and hay fever allergies are classified as seasonal. Perennial allergies are associated with dust, pets or other allergens that don’t disappear with the weather. Dr. Howard Langer, President of the Allergy, Asthma and Immunology Society of Ontario (visit http://allergyasthma. on.ca/allergy-websites, said in a telephone interview that changing a front lawn tree will not significantly decrease an allergy sufferer’s experience. “Being close to a tree makes little difference. With many thousands of trees in a forest, or multiple trees in a neighbourhood, one tree doesn’t change pollen levels. When walking under a tree, you don’t specifically suffer. Pollen is airborne and travels with the wind. It travels up to one and a half miles up in the air and even a few miles out into the ocean.” “It would be great if we could have less pollen in the air,” continued Langer, but there are other things allergy sufferers should consider. “People should wear long sleeves and gloves when pruning or contacting sap. If you are sweeping, you can be inhaling pollen directly.” What’s CANUFNET? The Canadian Urban Forest Network’s electronic discussion forum (CANUFNET) was initiated to “facilitate the exchange of ideas, opinions and concerns.” Andy Kenney, Faculty of Forestry at the University of Toronto, says on the website, “Please feel free to use this list in any way that you feel will contribute to advancing the cause of urban forestry in your jurisdiction or across the country.” However, please note that it is not for advertising.

Ontario Arborist (July/August 2012) • 27 Langer also said it is an interesting discussion to consider if whole city blocks were changed to low allergen trees. “This year, spring came three to four weeks early. People driving back from Florida in February suffered the entire trip as the trees bloomed in succession northward. When they reached Canada, they had about a week’s respite and then their allergies returned as pollination started north of the border.” Remember what it was like to see the world from the top of your favorite tree?

The National Post ran an article this spring on tree breeding and allergies. They suggested the allergy problem currently experienced in urban areas is due to tree breeding or because we stopped planting “messy” female trees. The story got a lot of press with cutie headlines like “Female trees: You can’t live with them. You can’t live without them” or “Botanical Sexism.” Their point was clear: we can blame our spring allergies on those damn tree breeders (who in turn will blame market conditions and customer preferences) or we can contribute to the discussion in an educated manner with the facts.

An artificial community where no maple, elm, alder or birch, the high allergy trees, are allowed to survive leads to the next issue: what are the consequences of a sterile society? We have the technology. We can plant all female trees or trees like pine that only produce heavy pollen. Here’s a summary of Barb Boysen’s response. She’s Coordinator of the Forest Gene Conservation Association: “The urban forest is not an island. It has great potential to contribute to natural gene flow, natural migration pathways and climate change effects.” The urban forest is becoming “a barrier to that gene flow, and with the sprawl effect this is increasing. Invasive or maladapted genes can pollute/dilute the native communities and gene pools. This is a huge issue and getting larger in southern Ontario.” Boysen continues, “I seriously appreciate the need for green and its benefits in the many totally artificial sites, but I hope we can do a lot better. The message we carry to clients, politicians and the public about what is at stake is a priority. If our profession doesn’t make the arguments, how can we expect them to appreciate it? Are we too pressured to just deliver anything green?” Stephen Smith, Urban Forest Associates Inc., contributed, “Actually non-natives often don’t do well either. They just tolerate the crappy conditions we put some of them in. If we do a decent job of preparing the site and caring for them during the establishment period, then both non-natives and natives do much better. I don’t even mind a few invasives like black locust and Siberian elm on some hostile sites. But the Tree of Heaven seeds too much.” Smith added in a telephone interview, “A lot of trees don’t do well in urban sites and it isn’t the fault of the tree. Norway maples sometimes fail to thrive and they are invasive.” Jennifer Koskinen of Stantec Consulting said, “Cities like Kitchener are currently developing new design guidelines that include better development requirements for street trees so that they can survive because they simply have not been in the past. I like the idea of the developments catering to trees instead of trees catering to developments.” David Schmitt, City of Kitchener and past ISAO President, said his guidelines are a work in progress and will be accessible later this summer. The Last Word Boysen argued: “We’re back to the original question and how to answer it. What stock to put where? It’s a matter of context – the unique complexity of local areas must be considered. Where one species is a big problem for some, it can be a solution for others.” “I’m asking about a checklist approach that may help all of us better address the Quick Facts: What Exactly is a “Tree of Heaven”? According to Wikipedia, Ailanthus altissima, commonly known as tree of heaven, ailanthus, or in Standard Chinese as chouchun (“malodorous tree”), is a deciduous tree in the Simaroubaceae family. It is native to both northeast and central China and Taiwan. Unlike other members of the genus Ailanthus, it is found in temperate climates rather than the tropics. The tree grows rapidly and is capable of reaching heights of 15 metres (49 ft) in 25 years. However, the species is also short lived and rarely lives more than 50 years. In China, the tree of heaven has a long and rich history. It was mentioned in the oldest extant Chinese dictionary and listed in countless Chinese medical texts for its purported ability to cure ailments ranging from mental illness to baldness. The roots, leaves and bark are still used today in traditional Chinese medicine, primarily as an astringent. The tree has been grown extensively both in China and abroad as a host plant for the ailanthus silkmoth, a moth involved in silk production. Ailanthus has become a part of western culture as well, with the tree serving as the central metaphor and subject matter of the best-selling American novel A Tree Grows in Brooklyn by Betty Smith. The tree was first brought from China to Europe in the 1740s and to the United States in 1784. It was one of the first trees brought west during a time when chinoiserie was dominating European arts, and was initially hailed as a beautiful garden specimen. However, enthusiasm soon waned after gardeners became familiar with its suckering habits and its foul smelling odour. Despite this, it was used extensively as a street tree during much of the 19th century. Outside of Europe and the United States, the plant has been spread to many other areas beyond its native range. In a number of these, it has become an invasive species due to its ability to quickly colonise disturbed areas and suppress competition with allelopathic chemicals. It is considered a noxious weed in Australia, the United States, New Zealand and several countries in southern and eastern Europe. The tree also resprouts vigorously when cut, making its eradication difficult and time consuming. In many urban areas, it has acquired the derisive nicknames of “ghetto palm” and “stink tree.” Interesting article: www.thestar.com/news/article/836481--the-heavenly-tree-with-a-seedy-side complexity of our own context. Not addressing or understanding that complexity is a historical problem.” “Many species were introduced here due to availability from the more mature and larger European and American markets. They were grown strategically for a particular market, but then they were marketed well beyond that market area.” “I’ve seen a lot of change in the last 20 years. Climate change awareness is actually growing and more people are interested in asking the question Will it grow well here? And most importantly, What exactly is it and where did it come from in the first place?” These are questions we should have been asking all along.” J Editor’s Note: If you need advice on a particular subject, or are wondering how other professionals across the country have dealt with an issue, post it on CANUFNET.

Ontario Arborist (July/August 2012) • 29 YOUR EDUCATION, continued from sidebar... What area of arboriculture interests you the most? It’s difficult to pinpoint one specific area. Forestry and tree conservation are both very rewarding for me. I’m also interested in invasive species removals, deadwood, cabling/bracing, and general care for woodlot trees. A property lucky enough to have heritage trees is fantastic. I feel we owe it to these trees to keep them around for future generations. As for tree sciences, it’s amazing how trees continually self engineer their physical matter in order to continue living. Finally, I like tree pathology because you have to look at so many factors, even the client, to see what “really happened” to the tree’s environment in the past. I find it very rewarding when you can clearly tell a client what is wrong with their tree and how we can help it. Educating anyone who does not know about their tree and how to take care of it is always satisfying. Do you feel your college experience has provided you with the necessary skills to operate your own tree care business? From a practical or technical skill set – yes. But, if I compare my past careers and education in hotel management, corporate banking or real estate sales to Humber’s arboriculture program, it did not have any small business integration. I do however give Humber instructors credit for finding opportunities to provide a “real world” take on... >> continued top of next page The BasicS Hometown: Richmond Hill, Ontario College: Humber Graduation Date: Spring 2010 Hobbies/Interests: Sailing, fishing, automobiles YOUR EDUCATION What is the single most important thing you have learned thus far? Arboriculture evolves continually. From climbing to tree science and safety, if you do not embrace change and recognize how it affects numerous aspects of tree care, it can negatively affect the tree, client satisfaction, your reputation and in the worst-case scenario, your life. >> continued top of page 30 • www.isaontario.com from the ground up! A Recent Student’s Perspective on the Arboriculture Industry Introducing Chris Timperon This column explores views of the tree care industry from those on the brink of their career, or those who have decided to return to school later in life. If you would like to be featured, download the questions online (www.isaontario.com, ‘About Us’ link, ‘Students’) and contact editor Joy Black. It’s great exposure and gets your opinions heard! what we were learning and how it could be applied in a business sense to a potential company in arboriculture. How do you think the arboriculture course can be improved? I think it would be an asset for Humber to provide a small business course. Many people in this industry want to be their own boss. It would be a real challenge to form a company right out of school without some business acumen. A small business intro within the arboriculture program would provide a basic foundation for entrepreneurs to get them thinking about daily operations, accounting, business plans, sales, hiring, interpersonal skills, etc. ism and cannibalization planet-wide on products that are forest dependent. The closing scenes could have some simple facts on how ignorance in caring for our own backyard tree could affect the tree, and in the end, all of us globally. Why is tree care important? It is important to mediate human interference in a tree’s natural life cycle. We bring city development, pollution, monocultures, introduction of foreign pests, etc. into the fray and there’s no going back. We have continually affected the natural environment and now must protect and care for trees so they can help keep the rest of us breathing fresh air in a stable climate. YOUR PHILOSOPHY YOUR FUTURE Why did you decide to become an arborist and/or was there a particular moment that cemented your decision? It took years for me to really see what What would be your ideal job in the arboriculture industry? I am active in many areas of tree care I was capable of doing naturally and enjoy at the same time. I eventually connected the dots over some critical years of my life and finally realized what made me happy. I was sitting in Madison Square Park in downtown Manhattan when it finally hit me. If your work makes you happy, then your success will follow naturally. Do you have a mentor, or who has been your greatest source of inspiration? Personally, my greatest source of inspiration has always been my parents. They have taught me how to really live one’s life and be happy, take chances and stay on course throughout any obstacle or criticism. Professionally, there are several industry people who make me strive to increase my knowledge in arboriculture and share it with others: Ian Bruce, Wayne Wakal, Mark Cooke and Matt Robertson. How would you explain an arborist’s role in combating climate change to a Grade 5 classroom? I was asked to speak to a kindergarten class last fall and was surprised how much they already knew. Perhaps by Grade 5 we could use a Michael Moore approach to drive home what they already understand. I would love to show a short dramatic video illustratinging how trees contribute to climates, different ecosystems, habitats, etc. Then I would contrast it with the never-ending destruction from consumer- from climbing, plant health care, quoting and marketing. I enjoy physical tree care very much and meeting with people to show them how we can help them and their trees. I think it will take time for me to see where to go from here so I am very open-minded. What are the employment attributes you value the most? Location (urban vs. rural), pay, responsibility, benefits, flex time, etc. A positive work-life balance is a huge plus if you are with a tree care company that supports that value. Everyone has a life outside of work and requires certain needs such as a steady income, good benefits and a salary to support where they are living. The city can be great, but it’s also expensive. I look forward to a more rural setting as I get older – and one with lots of trees! With my current role, I have good flexibility and the culture at Bruce Tree encourages me to work well and live well outside of work. Is job safety a concern for you? Job safety is very much a concern for me – and thankfully everyone else at Bruce Tree. We are all committed to safety and responsibility and we tend to look out for each other. Safety meetings and reviews are critical, but you still always have to be aware. Why do you think there is such a shortage of trained arborists in Canada and what steps can be taken to rectify the situation? There needs to be more public awareness of the arboriculture profession and the importance of trained arborists, bylaws and proper tree care. In addition, government agencies should increase their policing of permits and enforcement of tree bylaws. Like certified plumbers or electricians, if we become increasingly mandatory and in public demand, I feel there would be a natural increase in recognition for trained arborists. a Tamarack Tree Care Ltd. is a vegetation maintenance company headquartered in Brockville, Ontario that is expanding operations in Ontario with several full-time positions available.

Greetings tree enthusiasts! We are well into 2012 and the TREE Fund is actively involved in this year’s fund raising initiatives with the hope of once again achieving our $50,000 goal. A great time was had by all at the 3rd Annual Toronto Tree Fest in June; Team Canada is kicking into high gear for August’s Stihl Tour des Trees, and then we’ll wind down the summer season with the Harold Van Dyke Memorial Golf Tournament and a reTREEt re-plant (read on for details) in Goderich. W ith education and awareness of urban trees being a major focus of the Canadian Tree Fund, Toronto Island was once again host to the Annual Tree Fest on Saturday, June 9. A free ferry ride delivered folks to the starting point of the Tour of Trees, an interpretive tour identifying many of the unique tree species on the island. There were three versions – walking, cycling and the local tram – and all tours were guided by certified arborists to help identify, educate and answer questions. 32 • www.isaontario.com The tour ended at Franklin Gardens where a series of work and play stations were set up as well as a lively and entertaining stage show. Everyone enjoyed a funfilled and educational afternoon under partly sunny skies and moderate temperatures with lots to do, eat, watch and participate in. The City of Toronto sent some of their best arborists to give demonstrations of foot locking, aerial rescue and the uses of all their fine arboriculture equipment. The crowd was in awe and we may have attracted a few new “future arborists” to the industry. Maple Hill Tree Services set up and manned a junior tree climb that allowed kids to scale, unassisted, on a static line in the tree using friction knots. Children of all ages were able to ascend and descend under their own steam (see photo at bottom of adjacent page). Jim Menken, a local wood carver who has been transforming dead tree trunks into wonderful works of art throughout Mississauga and other municipalities, gave a demonstration and left a carving of an owl behind to become a permanent feature in the Gardens. Focus on reTREEt AMERICA The Canadian Tree Fund is considering the possibility of partnering with reTREEt America, a not-for-profit organization committed to planting trees in areas that have been damaged or destroyed by a natural disaster. Considered “second responders,” reTREEt arranges cycling/tree planting events in these communities after the dust has settled. Folks from all over North America come to volunteer to plant trees on residential properties where everything may have been lost. Ontario Event Goderich: Fall 2012 On stage, the crowd was entertained musically by award winning children’s entertainers Splash ‘N Boots and Washboard Hank, a local favourite band. Then both kids and adults alike were schooled through wit, humour and audience participation by the talented, yet sometimes forgetful, Professor Pricklethorn with his unique method of urban tree education. And cruising the waters around the Gardens was local arborist Tyler Ganton in his dragon boat carved from one piece of wood, truly an amazing work of art. Tyler also creates unique, useful furniture from wood salvaged from his daily practice. Following the event, Tour des Tree riders planted 20 black willows on the north shoreline of the island to help prevent future erosion. Tree Fest certainly seems to be gaining attention and interest from not only participants but also other groups, so stay tuned and don’t miss it next year. It just keeps getting better! a — Greg Hill T he core group is composed primarily of cyclists who have met over the years through the Tour des Trees and wanted to take the concept of cycling, planting trees, educating and raising awareness of the value of urban trees to a whole new level. Added to that, they are putting their time, energy and resources into helping improve the lives of those who have lost so much by giving them hope with new trees – and helping them realize that they are not alone and that people outside of their community care. The volunteers who participate in these events go home with so much more than they left behind because of the outpouring of gratitude for the gifts they planted. reTREEts are open to anyone, especially those who want to learn more about tree planting and cycling. And you don’t have to commit to all events – participate when and where you can. reTREEt America is planning an event in Goderich this fall to help replant residential properties in the town and outlying areas which were in the path of last summer’s tornado. They will be partnering with the local group “Goderich Trees” who have already done a great deal for local residents through spring tree planting efforts. The local municipality has developed a master plan to replant trees this fall on public properties with the focus being the main square in the heart of town (as this was a major attraction prior to the tornado). Following both of these fall events, Goderich’s new urban forest will be well on its way. Please consider getting involved as it is sizing up to be a fall that Goderich will remember for some time to come.

Simply visit our website at www.canadiantreefund. org and have your credit card handy. Canadians were the top team fundraiser in 2011 and hope to repeat in 2012. Read on for tour highlights from Mary DiCarlo, International TREE Fund. What’s so special about Tour 2012? 1) It’s our 20th Anniversary! In 1992, thirteen cyclists rolled out of Seattle on a mission to put their love of cycling and trees to work for the benefit of the urban forest. One week and 1,000 miles later they arrived in Oakland, California. They’d raised $89,000 for ISA’s Research Trust, which became the TREE Fund in 2002, and the consensus at the end of the ride was “Let’s do this again!” STIHL came on board in 2009 as the Tour’s Title Sponsor, and in 2011 the Tour raised a record $512,000 to support tree research and education, surpassing the $5 million mark for total funds raised by the Tour and effectively raising the bar for all future rides. 2) It’s in Oregon! Every day will be different, challenging and beautiful. There are good reasons why Oregon is on every serious cyclist’s “bucket list.” 3) Professor Elwood Pricklethorn (aka veteran Canadian Tour rider Warren Hoselton) headlines our educational programming again this year. Professor Pricklethorn’s entertaining and educational programs about how trees grow and why we need them are sure to have the kids of Oregon looking at trees in a different light this summer. We owe a big thank you to Warren for volunteering his time and considerable talent to educate kids about trees while we’re in Oregon, and to the Canadian TREE Fund and Bartlett Tree Experts for their support of our educational programming during the Tour. 34 • www.isaontario.com OCAA 2012: ed lehming Ontario Arborist Event Calendar August 5-11, Stihl Tour des Trees Cyclists will travel 585 miles this summer in Oregon and Team Canada is counting on your support!
