Iconic monarch butterfly needs protection as endangered species, advocacy groups say in US petition
By Martha Neil, ABA Journal
An iconic American butterfly needs protection as an endangered species because of climate change, the widespread use of a herbicide that has eliminated much of its food supply, and other factors, advocacy groups contend.
Joined by scientist Lincoln Brower, the Center for Biological Diversity, the Center for Food Safety and the Xerces Society filed a petition (PDF) on Tuesday with the U.S. Fish & Wildlife Service seeking protection for the monarch butterfly, whose population has dwindled from 1 billion to 35 million over the past 20 years.
