Public Lands Give Refuge To Endangered Species, Study Shows

Tufts University
Federally protected lands (light blue) stem the loss of endangered species' habitat compared to private unprotected lands (orange) in the U.S.

Federal lands are much better at reducing habitat loss and protecting endangered species than private lands, according to a new study out this week by researchers at Tufts University and the conservation group Defenders of Wildlife.

The study, published in Frontiers in Ecology and the Environment, "provides evidence that federal land protection and listing under the U.S. Endangered Species Act are effective tools for stemming losses in species habitat," according to a press release.

Adam Eichenwald was among the researchers to comb through more than three decades of satellite images of earth to track changes in habitat. He said this relatively new technique has made it easier for scientists to look at things at a much larger scale-which is increasingly important as wildlife moves across public-private and political boundaries with the changing climate.

"Because as the climate warms, as the climate changes, the habitats are going to be shifting and our species are going to be moving from place to place," Eichenwald said.

According to the study, habitat loss for imperiled species in the U.S. was more than twice as great on private lands than on federal lands.

The study also found that species generally lost less habitat after they were listed under the Endangered Species Act during the period of the study.
