12 Digest of Federal Resource Laws of Interest to the U.S. Fish and Wildlife Service Endangered Species Act of 1973: The ESA's primary goal is to prevent the extinction of imperiled plant and animals, and secondly, to recover and maintain those populations by removing or lessening threats to their survival. fws.gov/laws/lawsdigest/esact.html

13 The Secretary of Defense is authorized to specify exemptions from the Act for reasons of national security. The 1978 amendments also oblige the Secretary to consider the economic impact of designating critical habitat.

14 Critics of the ESA contend it is a failure because only 1% of the species under its protection have recovered and been delisted. They fail to explain how many species should have recovered by now. 80 %of species have not yet reached their expected recovery year. To test the success of the ESA, a study compared the actual recovery rate of 110 species with the projected recovery rate in their federal recovery plans. It found that the Endangered Species Act has a remarkably successful recovery rate: 90 percent of species are recovering at the rate specified by their federal recovery plan.

15 2006 analysis of all federally protected species in the Northeast: 93 percent were stabilized or improving since being put on the endangered species list 82 percent were on pace to meet recovery goals. Full Report: esasuccess.org/report_2012.html
