Monarch butterfly populations have declined by more than 80 percent since the 1990s due in large part to the widespread eradication of milkweed plants. Monarch caterpillars eat milkweed plants exclusively and butterflies rely on it to lay their eggs. 

The Endangered Species Coalition, our partner organizations, and activists around the country are working together to plant milkweed this spring and fall. On the map below, we have highlighted sites where we have planted milkweed or have scheduled planting events this year. We will be adding more locations as we get closer to the fall planting season.
