1 Wildlife in Jeopardy Education Kit Activity 24: Where s Wetland? Abstract Many species at risk around the world occur in wetland habitats. There are over 50 significant wetlands in Ontario south and east of the Canadian Shield. During this activity you will locate a wetland in your area then check out the plants and wildlife in this unique type of habitat. For families and Science, grades 4, 6, 7, 10 Academic, 10 Applied and Geography, grades 9 Academic and 9 Applied as well as Guides Conservation Badge and Scouts Conservation (Water) Badge.

2 Activity 24: Where s Wetland? 2 location of their school on the wetland map and then identify any nearby wetlands. As an outdoor component of this activity, arrange a field trip to one of these wetlands. If possible, try to go in late May or June when many wetland species will be active. Have students try to identify some wetland species using a field guide. Treading carefully, can students find and identify any of the following? ˆ Late May/early June marks the emergence of damselflies and dragonflies in wetlands. They are not only beautiful, they are also the natural predators of a variety of insects, including mosquitoes. ˆ Predators of insects can include plants! Look for the pitcher plant or sundew blooming in June/July in bogs and fens (some of them can stand two feet [0.66 metres] tall!). ˆ Look for turtles sunning themselves on exposed logs or rocks in ponds and marshes. Creep quietly though. Even though their hard shell protects them, they are very wary of intrusion and will often dive before you get a good look. ˆ Can you hear loud splashing? Do students see water being thrashed? This may indicate fish are spawning in the warm shallows of marshes, protected lakes, and bays. Figure 2: bullfrog ˆ Canada s largest frog, the bullfrog, breeds in June and July in marshes, lakes, and deep ponds. Have students look carefully for floating masses of jelly. Those may be the 12,000 to 22,000 eggs of the bullfrog. Look also for green, leopard and wood frogs.

3 Activity 24: Where s Wetland? 3 ˆ Are there arrow-shaped leaves and white flowers on some wetland plants? These are arrowhead plants, the tuberous roots of which are called wild potato. ˆ Are there any noticeable signs of wetland destruction such as pollution, garbage, housing developments, or evidence of acid precipitation? What can you, your class, and your community do to help preserve the remaining wetland habitat?
