Monarch populations have declined sharply. by around 80% - 95% since the 1980’s.
The Monarch butterfly is one of the most iconic pollinators in North America. Recognized for its bright orange wings and long-distance migration, monarchs have become a symbol of environmental change and the urgent need to protect our natural world.
Due to their decline, the monarch has been proposed for protection under the U.S. Endangered Species Act as a threatened species, a major step toward federal protection. In Canada, it is already listed as endangered.
While some recent population increases have offered hope, scientists emphasize that the long-term trend is still downward, and without continued conservation efforts, monarchs face a significant risk of extinction in the future. If we don’t do something, our children, or our children’s children, may never see a Monarch butterfly.
Why are Monarchs declining?
How can we help?
-
Create habitat wherever you can! Backyards, gardens, schoolyards, and every small space matters. Plant a mix of native flowers and allow some areas to grow naturally instead of fully manicured lawns. Push for sustainable development and regenerative farming practices.
-
Plant native milkweed species in your area. (Check regional planting guides) Milkweed is essential for Monarch reproduction. It’s the sole food source of Monarch caterpillars without it, they cannot survive. Even a few plants can make a difference.
-
Support climate-friendly choices! Plant trees, reduce energy use, refuse plastic and support conservation efforts. Creating gardens with diverse, native plants also helps ecosystems better adapt to changing conditions.
-
Think of your garden as part of a larger network. Planting pollinator-friendly spaces helps create “stepping stones” that monarchs can use during migration. Encourage community planting efforts to expand these connected habitats.
Monarch populations have dropped significantly over the last few decades due to a combination of environmental pressures:
Habitat loss from development and agriculture
Decline of milkweed, the only plant monarch caterpillars can eat
Pesticide and herbicide use, which reduces both milkweed and nectar plants
Climate change, which disrupts migration timing and breeding cycles
Fragmented landscapes, making migration more dangerous and less successful
