Capital Area Master Naturalists 2012 FIELD NOTES Meeting 28th March, 2012, Jeanette Larson, will discuss “Hummingbirds: Fact and Folklore.” Jeanette is the author of Hummingbirds: Facts and Folklore from the Americas. She will be happy to sign books for you and will have some to sell as well. Regular Monthly Meetings are normally the last Wednesday of each month (except December when we do not meet) and are held at 6:30, at the Austin Nature and Science Center, Zilker Park Map to Austin Nature Center http://bit.ly/hJ2Pli. All meetings are open to the public so bring a friend! Meridith O’Reilly Fro m th e P res id e n t Hi Everyone, When I first started this edition of Field Notes I thought, “wow, spring is here” but after today we seem to have reverted to winter again. We do need the rain of course but I was enjoying the warm but not too hot days. It was on a not so hot day that the new class and the “helpers” were treated to something really special. This baby rattlesnake had ventured out on to some stone steps to warm up in the morning sun. He was just beautiful. He put up with thirty plus visitors and was content to just watch and taste us. You can see how small he was when you realize that those are live oak leaves and live oak acorn cups. I returned later in the day just in time to catch him gliding away into the crack in the steps. It was a wonderful experience and lovely to be with people who were happy to leave him be. I hope you are all making great spring discoveries and enjoying this time with other like minded people. Have fun in the field. Christine Powell CAMN Board Meeting Join the Board of Directors for a spirited discussion about CAMN business at our next meeting on May 3rd, 2012.

Again it is another fine issue of the CAMN Field Notes and it is thanks to many of you. Almost all of the content comes from the members of our chapter. Some of our authors are "old hands," new “old hands and totally new hands! As always it is "the more, the merrier." It certainly makes light work for me when I see your contributions rolling in each month and can incorporate them into our "newspaper of record." I know I love to read about all we are doing and I am sure you do too. So please, if you see or do anything unusual, or even something you have been volunteering at for years tell us about it. Thanks again to all who sent me things - keep them coming. ! ! ! ! Christine Powell, Editor Do you have a Sighting to share? Thanks Heike for the great image. I know all of us are out there seeing wonderful things right now so please share! Send your sightings and interesting images of your volunteering events to the Editor so we can all share in the fun! I went for a walk in my back yard yesterday morning, to check on, and possibly clean out my bluebird nest boxes for the upcoming nesting season, when I looked down and found this mushroom. Isn't it beautiful? There was dew on everything and the air smelled moist and fresh. I had to run back to the house and get my camera. It was a glorious morning. I am not sure what type of mushroom this is, but I thought you might find the picture interesting for your monthly newsletter. Regards, Heike Laudien, 2012 CAMN group CAMN FIELD NOTES ! ! !

We packed Wild Basin with people, food and lots of fun. Our second silent auction was a huge success and I want to thank you all so very much for all your donations and for the great job you all did bidding on the amazing array of items. We even managed a few bidding wars but there were no hard feelings. This year we did have one crisis - I lost something I really wanted to Nancy Woolley,. Hey, being President has it’s rewards. I was able to persuade the artist who made the item to make another for me and I made a donation for the same as the winning bid to CAMN! So it worked out as a win, win for everyone all round. What item was that, you ask? Well, new CAMNer Meredith O’Reilly makes wonderful light or fan pulls in the shape of beautiful little bats - they truly are wonderful (see below). We are all so talented and it would be lovely to see more original handmade items in the auction next year. Wouldn’t that be great? So, if you create, then please consider sharing one of your originals with us next year. The silent auction is our major fundraiser as you know and this year, it, along with donations, brought in over $800. This money will be put to great use to keep the organization ticking over. It will also mean we can continue with Education and Outreach and continue to help our community to understand the importance of what is around them. Of course pins were awarded and it was a pleasure to realize the impact we have on the area around us. Over the next few weeks I am going to try and analyze just where we all do our volunteering and will give you an update on what I find out. I will also get David to put together a list of who received what and I will publish that too. There was lots of very good food, great conversation and much laughter. If you have never attended one of these events please do try next year, it really is a lot of fun. CAMN FIELD NOTES ! ! ! M A R C H 2 0 1 2! ! ! ! ! ! 3 Fi e l d S ur v ey s: Ma r s h a Ma y Wow! What a Great Opportunity! Biological Information Team Central Texas Project The goal for this project is to get professionals and hobbyists in the field for some fun botanizing, herping, birding and searching for inverts as well as organizing biological assessment teams for future surveys on other private lands within Central Texas. Another important goal for this project is to help fill the gaps in the Texas Natural Diversity Database. This database, maintained by TPWD, tracks rare species and habitats throughout the state and data is greatly needed. For this project there will be four survey teams: Plants, Reptiles and Amphibians, Birds and Invertebrates. gone 2.3 miles you will be at a Y with the left fork going to Diamond X ranch.

We all thought that the beautiful old Live Oak at Commons Ford would make a perfect backdrop to a class photo — and it does. This was the groups second class and what a wonderful day we all had. True to their past form they managed to find the beautiful baby rattle snake early in the day. He turned out to be popular with everyone and calmly hung around for us all morning while we all got photos and had lots of discussions about just what he was thinking coming out on such a cool day. Next up was a nice sized scorpion inside the kitchen of the house where we were conducting classes. Again, we all had a good look and then carefully removed him to a place of safety outside. What is it with this class and animals—last week turkeys this week reptiles and scorpions. It makes you wonder what will be next—dinosaurs maybe! CAMN FIELD NOTES ! ! !

M A R C H 2 0 1 2! ! ! ! ! ! 6 Field Prep: by Jim and Lynne Weber Morel of the Story Mycology, or the study of fungi, used to be considered a branch of botany, rather than a distant part of biology, until it was recognized that fungi are more closely related to animals than to plants. Mushrooms are the fruiting bodies of certain fungi, and while fewer than one thousand species have been identified in the state of Texas, it is estimated that as many as eight to ten thousand species remain to be identified! Often associated with molds, mildews, and yeasts, several mushroom species are edible, and the most avidly hunted of all wild mushrooms is the Common Morel (Morchella esculenta, pictured above). The cap of the Common Morel is sponge-like, yellowish gray to tan in color, oval to mildly elongated, and has a mottled, pitted surface. Its stalk is white, hollow, and has a slightly rubbery texture. This species is most commonly found in our state growing in the limestone soils of Central Texas, but it has also been found in the acidic soils of East Texas and in parts of the Big Bend country. It can be seen singly or in small groups on the ground under oaks and junipers, often along creek beds. Its species name, esculenta, means ‘good to eat’, and morels regularly appear on the menus of some the best restaurants. Although a process to grow these mushrooms under controlled conditions was reported years ago, attempts to commercially cultivate them have been far from successful. Laboratory studies have shown that common morels hold several medicinal properties, including immune system regulation, anti-tumor effects, fatigue resistance, and anti-viral properties. This species has long been used in traditional Chinese medicine to treat indigestion and shortness of breath, and is even listed in the National Register of Medicinal Plants in the country of Nepal. CAMN FIELD NOTES ! ! ! Mary Smiley Several similar species of morels are recognized in Texas, but the Common Morel is known by various colorful names, including yellow morel, sponge morel, Molly Moocher, haystack, and dryland fish. Members of this species can vary in size, color, as well as the shape of the cap. When cut down the center, the ‘true morels’ reveal a hollow stalk, unlike a ‘false morel’ that looks similar but the interior of its thick, white stalk is deeply furrowed or folded and not at all hollow. Care must be taken to properly distinguish between the two, as the False Morel (Gyromitra caroliniana) is toxic to humans. Mushrooms can be very photogenic and make for yet another reason for the whole family to walk new or familiar trails and see what earthy treasures can be found. While morels normally occur in the spring, they can appear after any unusual period of cool, rainy weather. And that’s the morel of the story!

John Abbot, PhD is the Curator of Entomology, Texas Natural Science Center at UT Austin. John led the day’s volunteer effort and worked pretty hard himself. While some volunteers planted native plants, removed invasive plants, and helped set up the greenhouse, most of us CAMNers were interested in creating an insect hotel. Never heard of an insect hotel? Neither had most of us, but we had all searched the web for examples and were excited to build hotels for the event. They are typically made from cast off items that are fashioned into an attractive yard sculpture that ultimately serves as habitat for insects. Of course, any critter is welcome. Insects like solitary bees or wasps use insect hotels as nesting areas, laying eggs and dragging prey back for their offspring. Other insects find them to be a welcome refuge, whether they winter over or just hang out in the shelter on a windy day. CAMNer Al Janelle was the man with a plan for our insect hotels. We started with cinder blocks, bricks, and salvaged wood. Diego and Mateo Carlson, along with their mom, Jennifer helped CAMNers Lynn Hill, Laura Southwick, Kim Lanzillotti, and Julia Osgood. We drilled holes in slices from tree stumps to serve as shelter for solitary wasps and bees and used dead twigs and ball moss to fill the nooks and crannies. After a day of work, volunteers had created three attractive and functional hotels that are free of charge for any insect that wants to move in. CAMN FIELD NOTES ! ! !

Find somewhere easily visible, perhaps close to a hedge, shrub bed or pond. Arrange some bricks on the ground on their side. If you have those with holes in them, face the holes outwards. If not, butt a pair of bricks together side by side and leave a small gap before the next pair. Try creating ‘H’ shaped cells of bricks and fill the space between with woodchips, leaf litter and sand (frogs and toads like to bury themselves into sand and soft soil). Lay a wooden pallet or strips of wood across the top of your bricks and then construct the next level in the same way. Remember to fill the gaps with your materials like hay, straw, dry leaf litter and wood chippings. Straw will provide nesting sites for ladybirds and thin twigs will provide shelter for larger insects. Place another pallet across the top and repeat. Logs and pine cones will provide extra homes for all sorts of insects. Keep your stack dry with roof tiles or a sheet of board covered in roofing felt or Made of recycled materials, wildlife stacks replicate natural features sought by wildlife in your garden — particularly by invertebrates such as ladybirds, many of which help control less welcome visitors. Wildlife stacks also provide refuges for frogs, toads and small mammals. You can make your stack as large or as small as you wish — the only limitations are your imagination. Be creative and provide lots of nooks and crannies using the materials at your disposal. Building a wildlife stack won’t just benefit wildlife — you’ll have the pleasure of being able to watch a host of different creatures making their homes and learn all about their fascinating behavior at close quarters. Wildlife stacks make an interesting alternative where it's not possible to have or include natural features in your garden. They're not a substitute for well structured vegetation and dead and decaying wood though, so ideally, try and provide them as well. CAMN FIELD NOTES ! ! ! M A R C H 2 0 1 2! ! polythene.

My sister and I decided to make the five plus hour trek. We arrived (after we had navigated the town in the rain) at the conference in time to make happy hour and dinner. I found Cliff and he invited us to the table to dine with them and we re-hashed lots of old owl stories. He told me he couldn’t impart much of substance regarding bluebirds to a bunch of bluebird experts, so his topic the next day would be woodpeckers. Woodpeckers! How does this tie into bluebirds? Well, he made it work. We listened to a discussion led by Greg Grant, horticulturist, conservationist and garden when the woodpecker appeared and started enlarging the writer, about using native plants to attract bluebirds and many opening cavity. Being ever ready with solutions, my brother other species.

M A R C H 2 0 1 2! ! ! ! ! ! 11 Fiel d Notes : M e r e d i t h O ’ R ei l l y A Wildlife Garden Begins with Healthy Soil A visit by American Robins to my yard this week was extra exciting for a couple of reasons. In years past, I’d see at most one annual Robin gracing my yard with its presence, but this year there were an estimated 50 Robins spread across the entire property all at one time. However, they absolutely refused to gather up for a group picture, despite my special request. But I was excited for another reason – to me, they were a sign that my wildlife garden is in good shape for spring. Perhaps the Robins had noticed what I’ve noticed, as well – my yard is filled with earthworms. I can’t dig a shovelful of soil without seeing many earthworms immediately, especially since recent rains revived the soil moisture content. But of course, the reality is that many of the earthworms we see here in Texas aren’t actually native. Although our state does have some native earthworms, what we often see are introduced earthworms brought to North America by Europeans long ago. They have managed to established themselves quite well on our continent – too well, perhaps. In northern areas, where glacial movements of the last Ice Age ended the presence of native earthworms, newcomer earthworms from other continents are proving to substantially harm the forest ecosystems. I can’t tell you much about our native Texas earthworms, nor can I tell you how they have been affected by the prolific presence of non-native earthworms. But I can tell you that down here in the South, earthworms in general are seen as beneficial rather than harmful. They pull organic matter into the soil to break it down, create passageways for air and water, release nutrient-rich wastes, help control harmful bacteria by consuming them, and loosen soil for root systems to penetrate. American Robins would probably add that they’re tasty, too, but I’m leaving that to the imagination rather than personal research. Not only do they have these and other benefits, but their mere presence is often considered an indicator of healthy soil. And that’s what our goal is for a wildlife garden – healthy soil. But what exactly does that mean? Healthy soil, regardless of earthworm presence, is soil that can naturally provide the nutrients and structure necessary for plant growth, particularly for plants that belong in that eco-region. And just like a healthy ecosystem above ground, there is an entire ecosystem within the soil. Organic matter, as well as carbohydrates provided by plants, feed bacteria and fungi, which in turn feed protozoa, nematodes, and arthropods. The waste products of these low-level predators provide nutrients in the form plants need, and they themselves become food for larger organisms, which ultimately become food sources for birds, mammals, and other creatures that are primarily part of the ecosystem above ground. If it sounds like I’m describing a food web, you’re right. Of course, there’s far more to it than that. For example, mycorrhizal fungi help plant roots better take in nutrients through a symbiotic relationship. And healthy soil actually has both beneficial and pathogenic organisms, but the former keep the latter in check by competing for resources or CAMN FIELD NOTES ! ! !

Furthermore, bacteria and other microorganisms help nutrients stay in the soil (unlike chemical products that just wash right through to our groundwater). poorer soil, mind you. Of course, be sure to stay away from chemical products completely (as I’m sure you already do) – they disrupt the underground ecosystem, killing off the beneficial organisms and preventing plants from doing their part in the soil. Truly, it’s fascinating what goes on under our feet. Thank goodness for all the tiny soil organisms that help natural gardens thrive. How do you help your soil be all that it can be? By the way, healthy soil smells really good. I’m serious. By simply following nature’s method of adding organic matter to So, in summary: It’s spring. Add compost. Go! the soil. You can do this by adding compost, or by just using leaf litter as mulch. Earthworms and other creatures will help pull the organic material into the soil, where the magic can happen.

This is one of the most enthusiastic groups on record, and that was obvious on March 3, when the group travelled to the Gault Site north of Florence on the Bell County line. The subject was archeology, and there is no more fitting setting than the richest Paleo-Indian site in North America. Literally millions of artifacts (mostly worked stone) have been collected here, where rich supplies of chert for tool-making can be found near water and food sources. This far exceeds the total collected at all other sites put together. Gault has been occupied nearly continuously for many thousand years, including use by at least one (and possibly two) groups that preceded the famous Clovis Culture, which used to be regarded as the oldest in America. A dominant feature is a huge midden of debris from centuries of food processing. The site is also home to the last surviving railcar (right) from the Bartlett and Western Railroad, which crossed northern Williamson County CAMN FIELD NOTES ! ! ! M A R C H 2 0 1 2! ! ! ! ! ! 14 Field Trip: Christine Powell and Dale Rye The Journey Continues… from 1909 to 1935. It is hard to imagine anywhere in the New World with more history. we saw a demonstration of the effectiveness of the dart-throwing lever known as an atlatl, a tool that the Aztecs later used for hunting and war. This was the only practical weapon for hunting the megafauna of the Paleo-Indian era from a safe distance. The class then viewed rock art from the time of initial European contact, less than a hundred yards from The format for the class was very different from a traditional classroom lecture. Dr. Clark Wernicke of the Gault School of Archeological Research led us from place to place, pointing out how archeology is done in practice. After visiting the rail car, the place where the remains of a butchered mammoth were found. Tools and fabrication debris literally covered the ground around us. A fairly short distance away is the site of the oldest structure yet found in North America.

Throughout the class, students pummeled Clark with apposite questions. Following lunch and an excellent presentation by the Education and Outreach Committee on the kits available to support CAMN’s educational endeavors, the group headed back towards Austin. Halfway there, we stopped at the South San Gabriel River crossing on U.S. 183 and hiked up the riverbed to view a set of well-preserved dinosaur tracks from the early Cretaceous Period. In the picture above, a CAMNer is standing by each print. The river runs across the top of the Glen Rose Formation, sediments laid down over 100 million years ago. The tracks in the South San Gabriel are about the same age as those along the Paluxy River in Dinosaur Valley State Park near Glen Rose, Texas. They were probably left by therapod dinosaurs like acrocanthrosaurus, one of the top predators between Allosaurus and Tyrannosaurus. Remains found in Oklahoma show an animal some 28 feet long from nose to tail tip. Although paleontology is not archaeology, the two subjects are so closely related that it seemed a shame to waste the opportunity to link the two on one Saturday adventure.

M A R C H 2 0 1 2! ! ! ! ! ! 16 Fiel d Meet in g: Dale Rye Hogzilla vs. The Environment Invasive species pose some of the greatest risks to Central Texas natural ecosystems, and one of the worst threats is the growing feral hog population. Our monthly CAMN speaker on February 29, Jared Timmons, is in the forefront of that battle. He works as an Extension Assistant for the Texas AgriLife Extension Service, focusing on the hog problem and other threats to the Plum Creek Watershed that runs from Buda and Mustang Ridge to the San Marcos River southeast of Luling. Many local homeowners know to their sorrow about the devastation that these animals can wreak on a garden, but the risks go far beyond that. Hogs (Sus scrofa) are a European import, but they have been going wild in Texas since the 1540s. Many domestic swine were released into the environment as Texans fled Santa Anna in the 1836 Runaway Scrape, and again from failed farms during the Great Depression. Russian boars imported for hunting became a significant part of the gene pool beginning in the 1890s. Today, sounders of 20–30 females and young, with an average weight of 100–150 pounds, range over areas of up to 19 square miles. Each female can produce 1–2 litters (with 4–6 piglets) every year. Boars are larger, occasionally up to 400 pounds, but are generally solitary. There are now millions of feral hogs found in most of the state, with populations continuing to rapidly rise. Thanks in part to their European origin, and in part to predator-control programs, they have no serious enemies in America other than human beings. eat uncultivated plants—they do about $52 million in damage to the agricultural industry in Texas, and that does not count the horticultural damage in suburban areas. In addition, feral hogs are omnivores that have become a leading predator of ground-nesting birds in parts of the state. Hogs are believed to be a major factor in the decline of the northern bobwhite and have been shown to heavily impact wild turkeys. Hogs may attack calves and other small livestock. They also indirectly threaten livestock and native species like the collared peccary (javelina) by competing for resources during times of scarcity like the recent drought. To top it all off, feral hogs can act as a vector for the spread of a number of serious animal and human diseases. Jared Timmons mentioned a number of these… but there are others. Imagine, if you will, the potential for swine flu developing in the feral population largely beyond human control. Much of the talk was devoted to various means that landowners may use to manage feral hog populations, including hunting, traps, and snares. There are currently no reliable and safe biological or chemical controls available, but there is a wealth of information on feral hog control measures from AgriLife Extension—which is one of the major sponsors of the Texas Master Naturalist Program, along with the Texas Parks and Wildlife Department. Most of these documents can be downloaded at http://plumcreek.tamu.edu/feralhogs. Even if Much of the funding for the Plum Creek Watershed Partnership you are not currently affected directly by the feral hog problem, comes from the federal Environmental Protection Agency. Why is you should be concerned. Non-landowners who are concerned the EPA interested in hogs? Well, because hogs have no sweat with the environment may wish to see if their local government glands, they cool off by wallowing in shallow water along the authorities are aware of the issue and what steps they are taking creek, its tributaries, and the adjacent lands, so they can cover to manage feral hogs. We in CAMN owe Jared Timmons a big themselves with insulating mud. This stirs up the bottom and thank you for helping to bring this to our attention. tears up the ground. In turn, that contributes mightily to turbidity on what should be a clear, spring-fed creek. The sediment and bacteria load from hog activity is a Jared Timmons fields questions from very interested CAMNers major reason why Plum Creek fails to meet Clean Water Act standards. This factor also affects water quality in many other bodies of water in Texas and throughout the nation. Other reasons why feral hogs constitute a threat include their effect on native plant communities, particularly in riparian areas. Because they eat acorns and large seeds and increase sapling mortality, hogs can significantly reduce the reproductive ability of oaks, hickories, and other valuable trees. The disturbed soil torn up by hog activity is likely to be repopulated by small-seeded invasive species like Chinese tallow. In an experiment by Rice and A&M researchers, a fenced tract protected from hogs had twice as many desirable trees and only half as many invasives, when compared with an adjacent unfenced tract. The fenced tract also had more forbs and better soil chemistry, while the unfenced tract had more bare ground and less diversity. Hogs don’t just CAMN FIELD NOTES ! ! !

All kinds of wildflowers are blooming. I have attached a few photos of them. Signs of spring in the birds include Cliff Swallows and Purple Martins. We also heard Carolina Chickadees singing. The grass is green and the leaves are starting to bud. Please get out and enjoy the changing season. Did we get some interesting birds? The list is kind of short today with 37 species. We did manage to get a couple of Pleated Woodpeckers and a Northern Flicker in a four woodpecker day. We got the Cliff Swallows and Purple Martins. We also got to see a Belted Kingfisher and an Osprey splash in to the water in an attempt to catch their lunch. All in all in was a fun and relaxed morning.

That means that our people are often intermingled with members of chapters in surrounding counties—El Camino Real in Milam County, Lost Pines in Bastrop County, Hays County Master Naturalists in (guess), Hill Country in Blanco County, Highland Lakes in Burnet County, and the Central Texas Chapter in Bell County. We have some particularly close neighbors among the Good Water Master Naturalists based in Georgetown. All of these chapters have their own programs, and this allows us to provide one another with Advanced Training Hours that we can apply towards initial and annual certification. tropical, Mediterranean, and temperate plants demonstrate human dependence on plants and show some of the ways to repair the scars of human exploitation. As quarries in the Capital Area become abandoned, Master Naturalists should be in the forefront in demanding that they are properly restored from eyesores to elegance. Recently, for example, several CAMN members were in attendance at a Good Water program in which geophysicist Sandi Phillips discussed “Quarries: From Eyesore to Elegant.” Because of our rich stone resources—including limestone around Austin and granite around Llano—Central Texas is home to an enormous number of quarries, some of them as large as three square miles in size. These have historically provided a major economic boost to the area. These benefits provide an offset to the detriments that quarries can create, in terms of esthetic, noise, dust, and water pollution problems. However, every quarry will eventually play out and be abandoned. Without sensitive restoration work, they will still provide all the detriments with none of the benefits. Ms. Phillips provided two examples of abandoned quarries that were converted into economic powerhouses for their regions. The first was Buchart Gardens on Vancouver Island near Victoria, British Columbia. This former cement plant and associated limestone quarry now draws over a million visitors a year who pay $30 admission, besides all the money they spend in the area for food and lodging. The 55-acre complex includes elegant gardens with blooms most of the year, thanks to the temperate marine climate. The other example was the Eden Project near St. Austell, Cornwall. This old clay pit was developed with money from the U.K. Millennium Fund. On thirty acres that was once barren, several “biomes” devoted to CAMN FIELD NOTES ! ! Google Maps - ©2012 Google !

Since then, this invasive pest has spread to at least fifteen states and Canada where it is killing millions of ash trees. To determine if EAB is in Texas, Texas AgriLife Extension (TAES) has installed and monitored some 200 traps per year since 2008, located in high risk areas (public parks and campgrounds, recreation areas, etc.). In 2012, the USDA Animal and Plant Health Inspection Service (APHIS) plans to greatly expand the EAB detection survey. For 2012, APHIS has solicited assistance from the Texas Forest Service (TFS), Texas A&M AgriLife Extension Service (TAES), Stephen F. Austin State University College of Forestry and Agriculture, and several volunteer citizen scientist groups. These agencies and volunteers have agreed to install some 700 survey traps in 71 Texas counties in 2012 in an attempt to determine if this beetle is present (see map right). Resembling a three-paneled box kite (left), the large, purple traps (24 x 14 inches), coated with non-toxic sticky material, will be baited with fragrant chemicals then placed in or near ash trees in state and federal parks, campgrounds, and on private lands, with the landowner’s permission. TAES at [email protected]. If the location is suitable, TFS or TAES personnel and/or volunteers will set up the large three-panel sticky trap in March and monitor it for EAB in June and August, removing the trap at the end of the season. No pesticides are used on the traps and there should be no significant risks to landowners. The option to adopt a trap will end on March 15, 2012. With your help, we can keep EAB out of Texas or detect infestations in early stages of development. The state’s ash resource is at stake. The traps will be hung six to ten feet above the ground and will display a “Do Not Disturb” sign. Any suspicious—looking beetles that resemble emerald ash borers will be collected for review by experts. The most challenging task now is to identify potential field locations for traps in targeted counties. The requirement is that each location must have one or more ash trees present and be accessible to field crews. If you know of a landowner with ash trees willing to host an EAB trap within one of the 71 counties highlighted in green on the map, contact Jim Houser, Regional Forest Health Coordinator with Texas Forest Service in Austin at [email protected]. If the property is located in East Texas, contact Joe Pase, Regional Forest Health Specialist in Lufkin at [email protected].

Nocturnal frog and toad calls were monitored on a monthly basis at Bauerle Ranch Park (formerly Slaughter Creek Greenbelt) and Mary Moore Searight Park in south Austin, Lake Creek Dam in north Austin, and Berry Springs Preserve in north Georgetown. Bauerle Ranch Park is 306 acres of mostly unimproved ranchland with a small pond formed by a ranch road spillway and fed by a tributary to Slaughter Creek. Mary Moore Searight Park is a city park that includes a portion of Slaughter Creek, Lake Creek Dam is a dammed up natural creek drainage area, and Berry Springs Preserve is a passive county park with a spring-fed pond and nearby creek. The drought of 2011 started making its effects known in April as water levels began to drop, and by July most creeks and ponds had almost (or completely) dried up. But at the end of the year, after a month of drizzle and showers in December, creeks were flowing slowly once more, and amazingly, a few frogs were heard calling again. Just add water! In 2011, nine CAMNers and six supporters of Bauerle Ranch Park logged a total of 68 hours across twelve months monitoring six amphibian species at Bauerle Pond: Bullfrog, Northern Cricket Frog, Gulf Coast Toad, Great Plains Narrow-Mouthed Toad, Green Tree Frog, and Leopard Frog. Three nocturnal bird species were observed: Yellow Crowned Night Heron, Common Nighthawk, and Chuck-Will’s-Widow. Additional birds often active around the pond at sunset and a bit thereafter were Black- bellied Whistling Ducks, Mourning Doves, Barn Swallows, Chimney Swifts, and Whip o’ Wills. Three snake species were also spotted occasionally in/around the pond: Red-striped Ribbon Snake, Diamondback Water Snake, and Blotched Water Snake. This was our second year of monitoring at this location, and Jerry Mayfield and Sandie Mayfield were the site coordinators. In 2011, eight CAMNers logged a total of 12 monitoring hours and observed six amphibian species at Mary Moore Searight Park: Rio Grande Leopard Frog, Bullfrog, Gulf Coast Toad, Green Treefrog, Northern Cricket Frogs and Gray Treefrog. Four nocturnal bird species were observed: Common Nighthawk, Yellow-crowned Night Heron, Eastern Screech-Owl, and Chuck-Will’sWidow. Two snake species were also spotted occasionally in/around the pond: Red-striped Ribbon Snake and Blotched Water Snake. This was our second year of monitoring at this location, and Julia Osgood is the site coordinator. The attendees at this location tend to live very nearby (one person walks over) so we do not record roundtrip miles or hours. In 2011, 11 CAMNers and four regular visitors logged over 625 roundtrip miles and almost 30 roundtrip hours for a total of 12 monitoring hours and observed five amphibian species at Lake Creek Dam: Rio Grande Leopard Frog, Bullfrog, Gulf Coast Toad, Green Treefrog, and Northern Cricket Frog. Two nocturnal bird species were also observed during three of the 12 months: Common Nighthawk and Great Horned Owl. This was our CAMN FIELD NOTES ! ! !

Since we monitor for the hour or so after sunset, a group provides safety in numbers in these public places. In addition, a team assures that there will be monitoring coverage of the site every month (i.e., not everyone has to make it every month). Plus, more eyes and ears mean that we observe more things – not just the amphibians and birds, but lots of other critters and plants, as well. In 2012, we plan to continue TAW at these four sites. Julia Osgood has moved out of the area, but someone else will be championing Mary Moore Searight Park.
