A Guide to Creating Monarch Friendly Habitat 31-33 3 How to Use this guide In southern Canada, the arrival of the monarch butterfly (Danaus plexippus) has been a sure sign that summer is around the corner. Unfortunately, this migration phenomenon is under threat. Significant population decline has meant fewer sightings of this iconic butterfly along roadsides, fields, in parks, and in gardens (Nature Canada, 2013). This guide is intended for use by educators, naturalists, and butterfly enthusiasts who wish to help create natural habitat corridors for monarchs throughout their migration route and summer range. This guide provides information on biology and lifecycle of the monarch butterfly, suggestions and tips on native plant gardening, and information about habitat requirements specific to monarchs. While our goal is to bring back the monarch butterfly, following the steps in this guide will help encourage biodiversity. As you add wildflower habitat, expect to see an increase in other species of pollinators like butterflies, hummingbirds, and native bees, along with birds and other wildlife. An Incredible Journey: The Monarch Butterfly Lifecycle and Biology The monarch butterfly goes through a process called complete metamorphosis1. The juvenile (caterpillar) is very different from the adult (butterfly). In this section we will explore the monarch lifecycle from egg to adult. Egg Each female lays several hundred eggs. Monarch eggs are usually laid individually on the underside of the leaves of the host plant, milkweed. Each egg is whitish in color, about the size of a pin-head, ridged, and similar in shape to a football. This section of the guide book was adapted from Journeys: Learning Activities from the Monarch Teacher Network, a publication by Monarch Teacher Network (www.MonarchTeacherNetwork.org) 1 4 A Guide to Creating Monarch Friendly Habitat The eggs hatch about 3-5 days after being laid. In the final day before the egg hatches, the top of the egg turns dark. When a monarch caterpillar first emerges, it often turns around and eats the egg shell for its first meal. Larvae (Caterpillar) The chief purpose of the caterpillar stage is to eat, eat, and eat some more, storing away the energy that the adult butterfly will need later. In order to store up energy, this caterpillar only consumes plants from the milkweed family. Though it may not be obvious at first, the caterpillar has three distinct body parts: head, thorax and abdomen. Caterpillar Anatomy tentacles thorax 12 3 1 abdomen 23 456 7 8 9-11 (fused) head true legs spiracles prolegs Monarch caterpillars shed their skins five times as they grow, and each stage (instar) between molts, can have strikingly different markings and patterns from the previous one. Generally, monarchs are caterpillars for eight to fourteen days under normal summer temperatures, but this can range up to 21 days in cool conditions. Some tips for finding the “age” of your caterpillar First instar Second instar Third instar Fourth instar Fifth instar “J” 1-4 days 1-3 days 1-3 days 2-5 days 3-6 days Front tentacles Front tentacles Front tentacles Front tentacles Front tentacles too small to still too short 1 - 2 mm long 4 - 6 mm long 9-13 mm long measure to measure Body length 2-6 mm Body length 5-10 mm Body almost Yellow/black transparent striping of body (no striping) with black head Body length 9-14 mm Body length 13-25mm Body length 24-64 mm Striping clearly visible, white “socks” above black “shoes” noticeable White, yellow and black stripes more vivid; white “socks” more distinct Stripes widen, obvious white “socks” diminish and appear like large dots Pupa (Chrysalis) The pupa or chrysalis stage normally lasts ten to fourteen days. The wings, legs and other external features of the adult butterfly can be seen on the outside of the developing pupa. The function of the gold dots on monarch pupae is essentially unknown, though there are several theories including light reflection which helps camouflage the pupa. About one day before the adult emerges, the green pupa changes color and becomes a “dark pupa”: the black and orange wings of the A Guide to Creating Monarch Friendly Habitat 5 adult can be seen as pigmentation is deposited in them. It is possible to sex a monarch pupa. The female has a vertical line in the segment below the paired dots next to the cremaster. Males do not. You will probably need a magnifying glass to see the difference. With & without Adult Male The primary job of the adult monarch is to reproduce. Monarchs Female first mate when they are at least three days old. When they mate, they generally remain together from afternoon until early the next morning, a period of about 12-16 hours. Females begin laying eggs right after their first mating and both sexes will mate multiple times. Summer monarchs live only about two to five weeks, but the final generation of late summer and early fall monarchs live up to nine months. These monarchs migrate to Mexico (or coastal California for monarchs west of the Rocky Mountains) until springtime (late February/ early March) allows them to return to Texas and the Gulf Coast states and lay eggs on new milkweed. Cool conditions in the overwintering sites slow their metabolism allowing them to save energy and live longer. When butterflies emerge, they are very fragile. Their wings are crumpled and moist. The adult monarch does a somersault as it emerges, then dangles from the empty chrysalis case. Over a period of about 15 minutes the wings fully emerge and straighten as fluid from the swollen abdomen is pumped into them. The proboscis, a soda straw-like tongue that the adult uses to sip nectar from flowers, is actually in two pieces at emergence. The adult rolls the two pieces out and back a number of times until they zip together as one. When not in use, the proboscis is curled up. It takes several hours for the wings to dry completely. The adult spins slowly about to assist in the drying process and begins to exercise its wings and flight muscles. During this time the adults expels an orange fluid, meconium, that contains waste products of the pupa stage. By mid to late afternoon the adults are more active and are ready to fly. Monarchs should not be handled the first day unless absolutely necessary. Monarchs have two pairs of wing sets which are covered with tiny scales that give the wings color. Individual scales are usually a single color. In butterflies, wing scales contribute to lift during flight, but not to drag, enabling them to glide for long periods. Scales also serve for thermal regulation and for warning coloration: the orange and black wing scales warn predators away, while the thorax is covered with long black scales that look like fur and keep the flight muscles warm and ready for flight. Male and female monarchs can be easily recognized. Males have a black spot on a vein of each hind wing. This is not present in the female. The veins of the wings are also darker and thicker in females, and the ends of the abdomens are shaped differently in males and females. Adult monarchs feed on nectar from flowers. Nectar gives them the energy to reproduce, and for migrating generations, fuels their epic journey. 6 A Guide to Creating Monarch Friendly Habitat Monarch Migration Each fall, many living things in Canada have the same problem: how to survive the winter? Monarch butterflies of Eastern North America have a unique solution to the problem of surviving sub-zero temperatures in Canada…fly 4,000 km to Mexico. It is an epic journey that is one of the most amazing natural wonders of the world. It is the longest known migration of any butterfly in the world (Bell et al., 1993). In North America, there are three main monarch populations, each with their own survival strategy. Monarchs west of the Rocky Mountains travel to small groves of trees along the California coast in places like Pacific Grove and Monterey. Monarchs east of the Rocky Mountains travel to the Transvolcanic Mountains in the Mexican state of Michoacán. The third North American monarch population is in lowland Mexico and Central America and is non-migratory because the milkweed is available all year round. In addition to the main populations, it appears that a small group of monarchs live year-round in Florida. Fall Migration Summer monarchs, generally those that emerge between mid-June and mid-August, in eastern North America live only two to five weeks. Their role is to build the population as quickly as possible. They are biologically and behaviorally different from the adult monarchs that emerge at the end of August through the end of September. The shorter days, cooler nights and aging milkweed of late summer are cues that signal to autumn monarchs that their journey south will begin soon. These autumn monarchs are in reproductive diapause: their reproductive organs are in a state of suspended development. They will not mate and instead are interested in migration. They will mate the following spring after spending the winter in Mexico. Spring Migration At winter’s end, monarchs change behavior and become more active. By mid-February, increasing temperatures and day length cause reproductive diapause to cease. Over a three to five week period, monarchs begin to mate in large numbers in preparation for the return migration. They begin to migrate north during the middle of March. By the end of March, the colonies have completely dispersed, flying north in search of milkweed on which to lay their eggs. It is these survivors that produce the new generation. Their children, grandchildren, and great-grandchildren re-colonize the northern states and provinces later that spring in a relay race of generations. Depending on the length of the growing season, there can be up to three or four generations of summer monarchs before the cycle of migration begins again. A Guide to Creating Monarch Friendly Habitat 7 Collecting and Rearing Monarch Butterflies Many people grew up with the idea that the way to study “bugs” is to collect them, kill them in a killing jar, and pin them in an insect collection. More and more people are finding that this is not half as interesting or humane as observing insects in their natural environment. Monarch caterpillars can be found just about anywhere that milkweed is found, especially from May to August. Because of predation and parasitism, rearing a wild caterpillar may save its life as it is estimated that there is only a 1% survival rate in the wild. If you decide that you would like to collect and rear monarchs, it is important to make sure that you follow regulations and behave ethically. Monarch Teacher Network of Canada (MTN of C) offers a two-day workshop that provides participants with the knowledge, skills, and resources necessary to provide a positive and ethical experience raising monarchs. Visit www.monarchteacher.ca to learn more. Legislation and Regulation In 1997, The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) listed the monarch butterfly as a species of special concern. The monarch butterfly was subsequently added to the Canadian Species at Risk Act (SARA) as a species of special concern. According to COSEWIC, the status of the monarch butterfly could be upgraded to threatened in the near future due to population decline in overwintering grounds in Mexico. The species is also listed as a species of special concern in the Endangered Species Acts in Ontario, Saskatchewan and British Columbia. In Ontario and Saskatchewan, the collection and rearing of monarch butterflies is a regulated activity. In Ontario, anyone wishing to raise monarchs needs to obtain a permit from the Ministry of Natural Resources (MNR). These permits are not generally awarded to individuals. If you plan to raise monarchs, visit our website www.monarchteacher.ca to find out more information about our group permit. Please note that you must be trained at our two-day workshop Teaching and Learning with Monarch Butterflies in order to qualify for our permit. In Saskatchewan, the Wildlife Act states that “[possession of monarchs is permitted if ] the person, is, or acts on behalf of, a museum, zoo, educational institution, scientific society or government and the person acquired [the monarch] from a person who was entitled to possess it pursuant to this subsection.” If you are uncertain whether your monarch raising activities are permitted under current legislation, contact your local branch of the Saskatchewan Ministry on Environment. Many municipalities also have by-laws prohibiting the collection of wildlife and plant species in local parks. This could mean that the collection of eggs, caterpillars, and/or milkweed is prohibited in municipal parks in your area. Before collecting any species in a local park or natural area, make sure you know your local bylaws and/or have permission. 8 A Guide to Creating Monarch Friendly Habitat Discovering Overwintering Sites: Tagging Until the 1970s, nobody in Canada knew where monarchs overwintered. It was generally thought that they migrated, but to where, no one knew. Dr. Fred Urquhart, a professor at the University of Toronto, started tagging monarchs in 1937 to try to answer the question; “where do monarchs go in the winter?” It took Dr. Urquhart, his wife Norah, and many volunteers nearly 40 years, but they finally discovered the monarchs’ overwintering site. It was over 4000 kms from Canada in the Transvolcanic Mountain range in the state of Michoacán Mexico (Monarch Teacher Network, 2011). The local people in Mexico had been celebrating the return of the monarchs for generations. However, they wondered where the monarchs went in the summer, just as Dr. Urquhart wondered where they went in the winter. Tagging had solved the mystery for everyone. Dr. Urquhart and his wife Norah used an “over the wing” tagging method that involved rubbing off some scales of the forewing and pasting a label over the leading edge of the wing. In 1992, the Monarch Watch program from the University of Kansas developed the more user-friendly sticky dot method that we now use. For more information on tagging or to order tags, contact Monarch Watch at www.monarchwatch.org. TIPS & TRICKS | Be Careful What You Model! If you decide to tag with a group, you want the participants to have MORE respect for living things, not less! Tagging monarchs implies it’s okay to grab and hold monarchs. Emphasize that butterflies are fragile and you should only handle them when you need to, for as long as you need to. Handling should be kept to a minimum and done carefully. A Guide to Creating Monarch Friendly Habitat 9 Monarchs Under Threat The monarch faces threats throughout its range. These threats have caused monarchs to be listed on Canadian species at risk acts. They have also resulted in a North American management plan for the monarch butterfly. The following threats to the monarch population have been identified by the North American Pollinator Protection Campaign (NAPPC, 2011). In Canada and the United States threats include: • The use of pesticides and herbicides. Pesticides, when applied broadly, kill both adult butterflies and caterpillars. In many areas milkweed is considered a noxious weed and herbicides are used to kill it, destroying monarch habitat in the process. • The loss of native plant species. • The propagation of non-native plant species and the escape of these species into natural areas. • Development, particularly urban sprawl, where large areas of land are stripped of vegetation to create new housing areas. • Damage to milkweed from ground-level ozone pollution (smog). •Drought. In Mexico the threats include: • Deforestation of the Oyamel fir forests where the eastern population of monarchs over winter, for housing, agriculture and sustenance. • Illegal logging. Besides destroying habitat, logging activities have also caused monarch populations to break up early, exposing them to late frosts in Canada and the United States. What can I do? The following section provides information on how to create habitat for monarch butterflies. By providing quality habitat throughout the monarch’s range, we can slowly start to address these threats. Additional ways to help include: • Educate others about the threats to monarch butterflies. • Advocate for monarch habitat in your area. • Use native plants in your garden. • Donate to monarch conservation. 10 A Guide to Creating Monarch Friendly Habitat GETTING STARTED Building Monarch Friendly Habitat – Milkweed and More If you are ready to start a monarch butterfly habitat project, it’s important to start with a plan. Careful planning will give your project the best chance for success. The following section provides a step-by-step guide to planning and implementing your project. Record as many details as possible to have good documentation of your project. Step 1 ~ Choose and Assess Your Site The first step in creating a monarch habitat project is to choose the site. The location and conditions of your site will influence the type and size of your project and the materials that you use. The best locations for monarch habitat are areas that receive full sun for most of the day. For more information on choosing a site and assessing the conditions (sunlight, moisture and soil), visit page 13. By failing to prepare, you are preparing to fail. ~ Benjamin Franklin Step 2 ~ Create Your Plant List Once you’ve selected and assessed your site, use this information to create a plant list. You will need to ensure that you’ve included milkweed species (page 16) and a variety of nectar plants (page 19). For additional support with species selection, consult your local native plant grower and/or the references section at the back of this guide. It is important that you keep track of the plant species in your garden. This will help you identify weeds, and allow you to document which plants have not survived. Once you’ve selected your species, record them in your plant list (Appendix 2). Step 3 ~ Sketch/Map Your Habitat For monarch habitat projects in shared spaces such as school yards, community centres or parks, it’s important to make a record of the original garden design. See Appendix 3 for a sample sketch and a blank grid to record your design. When creating your plan, for most beginners, it’s best to start with a small garden, then add to it over time if you wish. Think about whether you would like to choose a ground level garden or build raised garden beds – raised gardens provide easy access, better water drainage, better soil (less compaction), have fewer problems with trampling and usually less weed problems, but the initial startup costs are higher and they are not appropriate for large restoration projects. Think about adding in rock features or benches for sitting, a mulch path to invite people into garden and signs to label plants and increase the profile of your garden. A Guide to Creating Monarch Friendly Habitat 11 Step 4 ~ Create a Budget Before you go any further on your project, you probably want to draft a simple budget. This will help you decide on the scale of your project based on the funds that you have available and will help you determine whether you need to do any fundraising. To get started, fill out the sample budget in Appendix 4. Based on your budget and the size of your project, you may only need to purchase a few of these items or you may need to create your own spreadsheet if you are planning a larger project. Creating a budget is a great exercise if you anticipate applying for grants, because most granting organizations will ask for one. TIPS & TRICKS | Off-setting Costs • Talk to your local hardware store about donating tools. • Contact your local municipality or hydro company about mulch donations. • Ask your local community for plant donations, but be careful not to accept any invasive species. • Apply for funding. See the resources section for a list of potential funders. Step 5 ~ Plan for Ongoing Maintenance Before you create your monarch friendly habitat, it’s important to make a plan to maintain it. This will help you decide on the scale and complexity of your project. If you have only a very small group, start small. If you have a larger group with a lot of expertise, you might be able to take on a larger project. Regardless of the size of your project, it’s important to engage your grounds/maintenance staff during the planning stage of your project. They will be an excellent resource for your project, and definitely need to be engaged. Step 6 ~ Implement Your Project Now that you have a plan, it’s time to get started. This is the fun and exciting part of the project! If possible, make an event out of your planting day by inviting members of the community and the local media. For school projects, get parents involved. If you’ve received donations, invite donors to participate in your planting day. See Appendix 6 for a checklist to get you started. Most importantly, don’t forget to keep MTN of Canada updated on your progress. We love to receive stories and photos from our members! 12 A Guide to Creating Monarch Friendly Habitat Simple Steps for Choosing and Assessing a Location Location, Location, Location If your site is on public property or on a schoolyard, be sure to obtain proper permission before you go any further. You should also look at long term plans for the site (eg. future portable locations) to ensure that there are no conflicts between your project and future plans. There is nothing more frustrating than having a plan in place, or a project in the ground, and finding out you cannot proceed or your project will be removed. If possible, find a location that borders a tree line to provide protection from weather and predators. Consider a site that is away from busy streets and high foot traffic areas as these will be the most successful in attracting monarchs. It’s okay if you don’t have the perfect site; just choose the best site available to you. Other important considerations when choosing a location: • Is there an available water source? • What are the prevailing winds? A windbreak may be needed to keep butterflies on course. • Is it accessible to those with mobility challenges? • Is the location visible to the local community? This may increase buy-in and decrease vandalism. Site Conditions Once you’ve chosen your location the next step in planning your project is to assess the site conditions and record them in Appendix 1. The site conditions will help you determine which plant species are appropriate for your site. When visiting a plant nursery or researching plants online it’s important to check that any plants you select are adapted to the sunlight, moisture and soil conditions of your site. Sunlight Light conditions are an important consideration when planning a monarch habitat project. As mentioned previously, the best sites for monarch habitat have full sun throughout the day. Monarch butterflies are active from about 10 a.m. to 3 p.m. so it’s highly desirable to have your site receive full sun during this window. Use the table below to establish the light conditions present and record them in Appendix 1. Full Sun Part Shade Dappled Sun Shade 6+ hours of sun each day. 3-6 hours of sun each day, preferably in the morning and early afternoon. The sun that filters through the leaves of deciduous trees. Less than 3 hours of sun each day. A Guide to Creating Monarch Friendly Habitat 13 Moisture Whether you are planning a project in a marsh or a dry field, it is possible to create the right conditions for monarchs to thrive. To ensure success, it is very important to consider moisture conditions when creating a plant list. Is your site sandy and well drained? Or is it soggy and poorly drained? Also consider that the moisture conditions may vary throughout your site. Low lying areas or depressions generally retain more moisture than hills or slopes. Once you’ve assessed the conditions, record the information in Appendix 1 and consult the resources section to help you choose plants that are best adapted to the moisture conditions at your site. Consider that adult monarchs need a source of water for drinking. Plan to leave patches of bare soil where water can collect to make mud puddles. If your site is not naturally moist, consider creating mud puddles using a small saucer or bowl and adding water, sand and rocks for a dry landing surface. Soil One great benefit to using native plants in your garden is that they are adapted to local conditions, including the soils. Native plants don’t require applications of common soil enhancers like triple mix, manure, or commercial fertilizers. A little bit of mulch might be all you need for your garden. Even if you are planning to use only native plants, it’s still important to know what type of soil you have so you can select the best species or make amendments to the soil. The majority of nectar plants that the monarch butterfly relies upon are best suited for welldrained sandy soils. If you have a lot of silt or clay in your soil, you may need to add some sand to keep your monarch habitat growing. Use the jar test (Figure 1) to analyze the soil texture on your site and record your findings in Appendix 1. Use this information to choose species for your plant list. If you need additional assistance in creating a plant list, contact a local nursery for assistance, or consult the resources section in the back of this guide. FIGURE 1 | Soil Jar Test 1. Collect your soil sample. Floating organic matter Water Clay Silt Sand 2. Spread soil out on an old cookie tray to dry. Once dry, sift it through a collander or remove small stones and roots and break up any lumps. 3. Fill a jar halfway with the sifted soil and then fill it completely with water. Put the lid on the jar and shake well. 4. Place the jar in an undisturbed area and compare the results to this diagram. 5. If you see mostly sand in your jar, you have sandy soil. If you see mostly clay in your jar, you have clay soil. If you see equal amounts of clay, silt and sand in your jar, you have loamy soil. 14 A Guide to Creating Monarch Friendly Habitat Native Plants for Monarch Habitat The key to a thriving habitat is to put the right plant in the right place. This means ensuring that the plants you select are adapted to the climate, light, and soil conditions of your garden. Native plants have evolved over thousands of years in association with other species and in response to the local climate. Here are some suggestions for native plant species that are well adapted to climate conditions throughout the Canadian range of the monarch butterfly. Milkweed Without milkweed, there are no monarchs. Monarch caterpillars are specialists which means that they only feed on one species, milkweed. Milkweed is a pioneer species; it is one of the first to move into recently disturbed sites. This is why milkweed is so common along roadsides and in fields. There are about 100 milkweed species found in North America and 14 that grow in Canada. Milkweed is found in deserts to dry upland sites to swamps. Milkweed is a perennial plant that starts to appear relatively early in the spring, sprouting from underground rhizomes (roots) or last year’s seeds. Milkweed is deep rooted (up to 4 m) and can reproduce from a piece of root as small as 2.5 cm. In the right conditions, milkweed may begin to take over a garden or meadow. This is great for the monarchs but is something you may want to address when planning a restoration project (Monarch Teacher Network, 2011). HOW TO IDENTIFY MILKWEED (Monarch Teacher Network, 2011) • Leaves grow in opposite pairs along the stem. • Leaves and stems contain a milky sap. Contact with the sap should be avoided as it can have adverse effects if inadvertently rubbed in the eye, or consumed. • Flowers form dense clusters at the top of the stem. Individual flowers are “dumbbell” shaped with petals arranged 5-up, 5-down. • Common milkweed blooms from June-August in many parts of Canada. If you start them from seed, note that they do not flower in the first year. • In late summer, fertilized flowers form seed pods. Pods contain hundreds of brown seeds each with about 900 long, white hairs attached. These hairs help the seeds get caught in the wind to aid dispersal. A Guide to Creating Monarch Friendly Habitat 15 MILKWEED VARIETIES FOUND IN CANADA Common milkweed – Asclepias syriaca Other names: silkweed Natural range: Saskatchewan, Manitoba, Ontario, Quebec, Maritime Provinces Habitat: roadsides, fields, meadows & rocky flat areas Bloom time: June to early August Planting tips: Plant in full sun. May be too invasive for small backyard gardens, but is appropriate for larger sites. Start from seed for best results (Nature Canada, 2013). Butterfly milkweed – Asclepias tuberosa Other names: butterfly weed, orange swallowwort, pleurisy weed Natural range: Ontario, Quebec, Habitat: Roadsides, disturbed areas, dry fields, prairies. Bloom time: June to September Planting tips: This species needs full sun to partial shade and well-drained sandy soils or coarse soils. This species is well adapted to gardens. Propagate from cuttings (in May for best results) or start from seeds (Nature Canada, 2013). Swamp milkweed – Asclepias incarnata Other names: rose milkweed, silkweed, marsh milkweed, water nerve root Natural range: Manitoba, Ontario, Quebec, Maritime Provinces Habitat: Swamps, marshes and other wet areas. Found on streambanks, lakeshores, in sedge meadows, marshes and low wet woods. Bloom time: Late June through August, occasionally into September Planting tips: This species is found in wet areas with full sun exposure. They are great for shoreline restoration projects. Sow seeds into out flats in late fall & mulch lightly (Nature Canada, 2013). 16 A Guide to Creating Monarch Friendly Habitat MILKWEED VARIETIES FOUND IN CANADA Showy milkweed – Asclepias speciosa Natural range: British Columbia, Alberta, Saskatchewan, Manitoba Habitat: Found in ditches, road sides & other disturbed areas. Preferred habitats include savannahs, forest edges, meadows & fields. Bloom time: June to August Planting tips: This species thrives in full sun, sandy loam soils & moisture conditions from dry to moist. Whorled milkweed – Asclepias verticillata Other names: white/eastern whorled milkweed Natural range: Manitoba, Saskatchewan, Ontario Habitat: Woodland, savannah, and prairie habitats. Bloom time: May to July Planting tips: Plant in dry sandy soils in full sun or part shade. Choose locations near forest edges or windbreaks. Other milkweed species to also consider depending on your region: Green milkweed - A. viridifolia: BC to ON Hairy milkweed - A. lanuginosa: prairie region Oval-leaved milkweed - Asclepias ovalifolia: BC to ON Poke milkweed - A. exaltata: ON, QC Purple milkweed - A. purpurascens : ON A Guide to Creating Monarch Friendly Habitat 17 TIPS & TRICKS | Milkweed Look-alike Hemp dogbane (Apocynum cannabinum) is not milkweed. Monarch caterpillars will not feed on dogbane, so it’s important to learn to distinguish it from common milkweed Common milkweed – Asclepias syriaca Hemp dogbane – dogbane, indian hemp • Seedlings and shoots hairy • Seedlings and shoots smooth • Single stalk • Branched stalk • Flowers pinky-purple; 5-up, 5-down petal arrangement • Flowers greenish-white, smaller, cup shaped • Oval shaped pod • Long bean-like pod Nectar Plants for Adults Monarch habitats require a variety of nectar sources for adult butterflies. Summer wildflowers feed monarchs through the breeding season and fall wildflowers provide fuel for their long journey south. For best results choose a site with full sun and use a variety of flowers that bloom throughout the growing season. 18 A Guide to Creating Monarch Friendly Habitat Below are some suggestions for plants that are adapted to climatic conditions throughout the Canadian range of the monarch butterfly; however, you should use local plant lists to select species that are native to your site.

We’ve highlighted four herbicide free ways to prepare your site for planting. 1.In the fall, place black landscape fabric, or newspaper layered with mulch, over the area where you wish to plant. This should smother any sod and most weeds. Remove any dead material before planting. 2.Use a spade to remove the existing sod. This will form a depression which will need to be filled with soil or clean fill (for small project only). 3.To create a simple raised bed, use reclaimed lumber or wood pallets to create a frame. If you need help building the frames, this can be a great opportunity to engage the local community or a woodshop class. Once your frames are in place, put down cardboard or newspaper over the existing sod or weeds and fill the container with soil. 4.Till the area 6-8 weeks prior to planting. You may need to till on multiple occasions to eliminate weed growth. Remove any weeds and dead vegetation (best method for large restoration projects). BASIC TOOL CHECKLIST Gardening Gloves (1 pair/person) Trowels (1/person) Buckets (for mulch/water) Rake Shovel Hose (or watering cans) Signs/tongue depressors (for labeling plants) Permanent marker Hand washing Station (if no running water available) Planting your beds Here are some suggestions to help ensure that your planting day goes smoothly and your plants have the best chance of survival. • If you are planting in a publicly accessible space, make sure to invite the local community, and even the local media, to raise public awareness and ensure buy-in for your project. • Plan your planting day for the spring, after the last hard frost in your area, or early fall. • Try to plan your wildflower purchases and deliveries so they can be planted immediately. If you can’t, make sure to keep them watered and in a shady, sheltered place until you can plant them. •Make a plan for watering your beds. Try to plant your beds when there is rain in the forecast. This won’t always be feasible so make sure that you have everything you need on hand to water your flowers immediately. 20 A Guide to Creating Monarch Friendly Habitat • Label your plant markers with the plant name and date before you head outdoors. •If it has been a while since you prepared your beds, then they may have hardened in the rain. Break up the crust with a rake and weed as necessary. • Place signs or physical barriers around your garden or habitat if possible. Sometimes butterfly gardens and meadows can fall victim to trampling or overzealous mowing, so it is important to ensure that your site is well marked. A Guide to Creating Monarch Friendly Habitat 21 10 TIPS FOR A SUCCESSFUL MONARCH FRIENDLY GARDEN (Monarch Teacher Network, 2011) •Start small. You can always enlarge the garden later on as you gain confidence or more people join in. •Enlist the support/help of other people. Engaging the local community is the key to your success. Educate and involve them; plan for summer help. •Locate the garden in a sunny area. Butterflies and most butterfly-attracting plants need bright sunshine. •Think two kinds of plants: nectar sources and host plants. Butterflies visit flowers in search of nectar to eat so you need to have nectar-producing flowers in your garden. But you also want to have host plants that provide food for caterpillars and that will lure female butterflies to lay eggs on them. Different kinds of butterflies require different host plants. •Think water source. It will be very difficult to keep your garden alive during the summer or periods of drought unless you have an easy water source. Is there a faucet nearby, or can one be created? In the long-term, carrying buckets will not work. Soaker hoses buried in the ground are also a good idea. Mulching the garden will save water and suppress weeds; lawn clippings are good mulch. •Include both annuals and perennials. Use native plants where possible. Both seeds and seedlings of native plants can be purchased locally and planted directly in the garden in either mid-June or late August/early September. Seeds can be started indoors in late winter and transplanted into the garden as seedlings in the spring. Using native plants provides butterflies, insects, birds and mammals of your area a food source they can use throughout the growing season. •Consider having a damp area or shallow puddle in the garden. Some butterflies drink and extract minerals from moist soil. Sometimes large number of butterflies will gather for a drink, “puddling”. •Consider placing flat stones in the garden. Butterflies often perch on stones, bare soil or vegetation, spread their wings and bask in the sun to raise their body temperature. •Plan for plants to bloom through the growing season. Butterflies are active from early spring to late fall. Plant a selection of flowers that provide nectar throughout the entire growing season. Remove spent blooms (deadheads) on a regular basis to encourage new flowers and continuous nectar. •Do not use pesticides in or near the garden. Most traditional garden pesticides are toxic to butterflies. Use predatory insects or hand remove pests. 22 A Guide to Creating Monarch Friendly Habitat Maintenance Requirements The calendar below provides a general guide to the seasonal maintenance requirements for your garden (TRCA, 2012). For more detailed instructions on maintenance refer to the resources section of the guide.

Taking care of your monarch friendly habitat will require ongoing team work. Once your garden is established you might want to recruit a maintenance team and assign tasks/ responsibilities to each team member. To get organized use the job sheet in Appendix 5. This will help divide up tasks and align your students/volunteers with the things they like to do. In a school setting, these tasks could be assigned to different classes or to students within one classroom. A Guide to Creating Monarch Friendly Habitat 23 APPENDICES Appendix 1. Site Observations Use this space to record observations about your site. This should include the sunlight conditions, soil type and moisture conditions, where possible. It could also include notes about site specific challenges, ideas for plant species or ideas for improving the site conditions. Sunlight: Full Sun Part Shade Dappled Sun Full Shade Comments: Soil Type: SandSilt Clay Comments: Moisture Conditions: Wet/poorly drained Moist Dry Comments: Additional Notes: 24 A Guide to Creating Monarch Friendly Habitat Appendix 2. Plant List Use this sheet to keep a record of the species in your monarch friendly habitat. You should also record the location of the plants on your habitat sketch. It’s important to include both the Latin and common name if possible. Plants often have many common names depending on the local region and some common names are used to describe completely different species of plants. The Latin name provides a universal ID for plants across regions and languages. Using the Latin name makes it much easier to research a plant species online and to ensure you get the correct species when you visit a nursery or local native plant grower.

Monarch Habitat Sketch Use the space below to create a sketch of your monarch habitat project. Record the location of buildings, key features, hardscaping (rocks, pavement, benches, etc.) and plant beds. Indicate the species of plants so that you can locate them later. If you need more space, you can use a standard (8.5” x 11”) sheet of graph paper to create your sketch. 26 A Guide to Creating Monarch Friendly Habitat Below is a sample monarch habitat sketch. It is drawn to show plants in full bloom, but thanks to the grid format you can use this the following year to know what plants will be growing where.
