On August 26, 2014, The Center for Biological Diversity, Center for Food Safety, The Xerces Society for Invertebrate Conservation, and renowned monarch scientist Dr. Lincoln Brower filed a legal petition with the U.S. Fish and Wildlife Service (Service) seeking Endangered Species Act (ESA) protection for monarch butterflies, whose numbers have dropped dramatically over the past two decades.
