Monarchs and the Endangered Species Act
In 2014 the monarch butterfly was proposed for listing under the federal Endangered Species Act through a petition submitted by the Xerces Society and conservation partners, including the Center for Biological Diversity, Center for Food Safety, and the late Dr. Lincoln Brower. On December 15, 2020, the U.S. Fish and Wildlife Service announced that listing the monarch butterfly under the Endangered Species Act is warranted, but precluded by other priorities. This means that the species is a Candidate species under the Endangered Species Act.
