The report, authored by researchers at Tucson, Arizona-based advocacy group Biological Diversity, analyzed 169 peer reviews authored by scientists the FWS commissioned between 2002 and 2007 when making determinations about how much "critical habitat" to set aside for the protection of endangered species. The authors found that in more than 90 percent of cases, the agency decided to shrink critical habitat areas even in the face of peer reviews that suggested the species would be better served by increasing protected areas. "It's very hard to imagine circumstances where less habitat translates to a better outcome," Duke University biologist and study coauthor Stuart Pimm told ScienceInsider.
