The Monarch Butterfly is one of the most iconic species in North America. Each year, these remarkable creatures migrate from Canada and across the U.S. to gather by the thousands in overwintering forests of central Mexico and coastal California. However, Monarch numbers in North America continue to decline. We have the opportunity to protect these dear pollinators.

Public comments on a proposed rule to list the Monarch Butterfly as a threatened species under the Endangered Species Act will be accepted through May 19th, 2025. The listing proposal is accompanied by a proposed critical habitat designation for the species at their overwintering grounds in coastal California. In addition, a proposed 4(d) rule that offers species-specific protections and flexibilities to encourage conservation. Your support is critical to setting these regulations.

According to the most recent monarch Species Status Assessment, the probability of extinction for Eastern Monarchs ranges from 56 to 74%, and the probability of extinction for Western Monarchs is greater than 95% by 2080. Threats to the species include, but are not limited to:

• The loss and degradation of breeding, migratory, and overwintering habitat 
• Exposure to insecticides 
• The effects of climate change  

But these threats are within our control, and listing the Monarch Butterfly under the Endangered Species Act provides crucial protections. Please speak out today on behalf of our Monarch Butterfly. Taking action to protect them will send ripples of benefits across our North American ecosystems.
