Focusing solely on crop pollination and failing to take the pollination of native plants into account may well lead to a deterioration in the plant communities that make up the very fabric of our environment.

Instead of rearing—which is risky and unproven in helping monarchs—we should focus on more effective, science-backed ways to conserve these glorious wild animals.

The Endangered Species Act is our nation’s most effective law for protecting animals and plants in danger of extinction, and it has prevented 99% of listed species from going extinct. We need your voice to help defend this crucial law.

We’ve made the case that roadsides can be managed for pollinators, while maintaining erosion control, keeping roads safe, improving water quality, and saving money! Now it’s time to make the case to lawmakers, so that they can change the way their state manages roadsides for multiple benefits, including helping bees, butterflies, and other insects.

Recent research suggests that pollinators do better in urban environments, yet these mowed, mulched, and managed landscapes frequently lack a sufficient amount of nesting habitat needed to support large numbers of bees. As wild bees move off ag lands and head for the cities and suburbs, they may struggle to find their “dream home” amongst ours.

Few realize that many native grasses serve as the larval host plants for a diversity of skipper butterflies. Little bluestem is one of the showiest and easiest grasses to add to your pollinator paradise.

Roadsides may not seem like an ideal place for pollinator habitat - but they can be managed to provide millions of miles of high-quality habitat. In some places, they may be the only opportunity for providing lrge-scale resources for pollinators.
