Give monarch butterflies the proven protection of the Endangered Species Act

We urge you to make the right decision and list monarch butterflies under the Endangered Species Act (ESA) on or before the listing due date this June.

In the 1980s, about 4.5 million butterflies spent winter along the California coast. This year? By last count, there were only about 30,000. It's clear that monarch butterflies need action now. The Endangered Species Act has seen incredible success since it was established 46 years ago: 99 percent of the animals listed under the ESA are still with us today. Monarch butterflies need the proven protection that the ESA can provide.
