Wednesday, March 20 at 11 a.m.

Enacted in 1973, the Endangered Species Act (ESA) requires all federal agencies to consider the impact to threatened and endangered species and their critical habitat when making decisions. The Environmental Protection Agency (EPA) has faced numerous lawsuits for its failure to consider the Act when issuing pesticide registrations—resulting in a 2023 commitment from the Agency’s Office of Pesticide Programs that puts the ESA at the forefront of all future registrations and some registration renewals.
