"Each autumn millions of monarch butterflies migrate south. Monarchs leave the eastern U.S. for fewer than 20 sites in Mexico. The forests where they wait out the winter are threatened by development and logging. In 1983 the World Conservation Union declared the monarch migration a threatened natural phenomenon."

Plant native milkweed from central Mexico through the U.S. Midwest to southern Canada—the only plant monarchs lay eggs on.
Grow native nectar flowers like blazing star, coneflower, and goldenrod to feed adult monarchs along their migration routes.
Avoid pesticides and herbicides, especially neonicotinoids, which kill caterpillars and pollinators.
Buy FSC-certified paper and wood products to protect overwintering forests in Mexico.
Track individual butterflies and record your monarch sightings on the free Project Monarch Science app
