Monarchs are one of our most fascinating butterfly species and have captured world-wide attention with their annual migration between Canada and Mexico. Unfortunately, climate change and human impacts on critical breeding and wintering grounds threaten the future of Monarch butterfly populations. The World Wildlife Fund created “Teaching Tools About Monarchs”, a compilation of learning resources, to actively engage students in exploring connections between the environment, human activity and the health of Monarch butterfly populations. Don't Treat Soils Like Dirt is one of several lessons in the toolkit.
Students investigate the important role western Canada's wild grasslands play in providing summer habitat for Monarchs. They focus on the interrelationships between the physical and biological components of this ecosystem by:
Analyzing how organic matter helps improve moisture retention and drainage in grassland soils.
Comparing and contrasting plant growth in healthy and unhealthy soils.
Identifying threats to native grasslands.
Brainstorming personal conservation actions.
This activity supports science outcomes related to habitats, ecosystems, biodiversity and plant ecology.
Like many other pollinators, Monarch butterflies are threatened by the loss of native food plants. Students could build on learning about plant growth and healthy soils to involve a community-based gardening group in establishing wildflower beds on school grounds. This project could become the basis of a public awareness campaign that encourages homeowners to include more native plants in their perennial gardens. A class could also prepare and deliver a presentation to the local municipal government to identify how green spaces could be improved with flower species that benefit pollinating insects like the Monarch butterfly.
