Recovery of an Endangered Provision: Untangling and Reviving Critical Habitat Under the Endangered Species Act

Recovery—the regaining or restoration of something lost—is the heart and soul of the Endangered Species Act, with critical habitat designation and protection forming its primary structural support. Yet nearly four decades after the ESA's enactment, critical habitat has failed to become the recovery tool Congress intended. Confusion plagues courts, agencies, and environmental organizations regarding the legal, environmental, and economic impacts of designating critical habitat for threatened or endangered species. The confusion stems from a misinterpretation of the statute: implementing agencies have perceived the jeopardy standard and adverse modification standard as identical, leading them to designate critical habitat rarely and protect inadequately habitat already designated. Recent case law has adjusted these standards, complicating the landscape considerably. Robbins untangles this confusion by demonstrating that critical habitat must add value beyond listing protections and that its value exists entirely in relation to protection from jeopardy that listed species already enjoy. The functional equivalence theory distorts critical habitat's purpose by suggesting it adds no further protections. Robbins proposes statutory interpretation reflecting Congress's holistic plan, arguing that regulations defining jeopardy and adverse modification should be redrafted to reflect this distinction. She recommends modifying the critical habitat designation method and emphasizes that agencies must begin designating critical habitat for species already listed.
