Under new proposals, wildlife managers would limit protections for species designated as “threatened” (a level below endangered), consider the economic costs prior to defending a species, and de-emphasize long-term threats such as climate change.

The proposals follow Republican bills and budget riders that would remove protections for gray wolves in the lower 48 states, exempt the greater sage-grouse from an ESA listing for 10 years, and increase state involvement in conservation decisions.

Those who study the ESA agree that reforms are needed – but the current proposals on the table are unlikely to solve the problems experts identify.
