Biden-Harris Administration Proposes to Strengthen Protection and Recovery of Threatened and Endangered Wildlife

WASHINGTON – As the nation honors the 50th anniversary of the Endangered Species Act, the U.S. Fish and Wildlife Service and NOAA’s National Marine Fisheries Service (NOAA Fisheries) are proposing to restore important protections for species, strengthen consultation and listing processes, and reaffirm the central role science plays in decisions that guide the protection and recovery of endangered and threatened wildlife.

“The Endangered Species Act is the nation’s foremost conservation law that prevents the extinction of species and supports their recovery,” said U.S. Fish and Wildlife Service Director Martha Williams. “These proposed revisions reaffirm our commitment to conserving America’s wildlife and ensuring the Endangered Species Act works for both species and people.”  

“Through the Endangered Species Act, we take a science-based approach to protect threatened and endangered species and their habitats,” said NOAA Fisheries Assistant Administrator Janet Coit. “These proposed regulatory updates will help ensure the Act continues to serve as an effective conservation tool in the face of continued challenges, including biodiversity loss and climate change climate change
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.

Two separate proposed rules address the responsibilities that the Service and NOAA Fisheries share regarding interagency cooperation, species classification, and critical habitat designations under the Endangered Species Act. A third proposed rule, issued by the U.S. Fish and Wildlife Service, addresses the protections afforded to species listed as threatened.

The agencies are jointly proposing the following changes to the implementing regulations with the intent to improve both agencies’ ability to fulfill their responsibilities under the ESA to protect and recover listed species. The two joint rules include:

  • Improve the interagency consultation process. Revising language, definitions, and responsibilities that would further clarify and improve the federal interagency consultation processes, including revising the scope of reasonable and prudent measures in an incidental take statement to improve conservation outcomes.
  • Clarify standards for listing, delisting, and reclassifying species, and revising some criteria for critical habitat designations. Reinstating prior language reflecting congressional intent that listing, reclassification, and delisting determinations must be made “without reference to possible economic or other impacts of such determination” to make clear that any economic impacts stemming from the listing, reclassifying, or delisting of a species are not considered when making classification decisions, along with other changes to improve the transparency of the listing process and revising some of the criteria for designating critical habitat.

The third rule, addressing protections for threatened species, is proposed by the Service:

  • Reinstate protections for species listed as threatened under the ESA. Reinstating theblanket 4(d) rule will provide a base level of protection (a “safety net”) for all species listed as threatened while retaining the option for the Service to adopt a species-specific 4(d) rule.

Both agencies are committed to applying the best available science when implementing the Endangered Species Act — including when making listing and delisting decisions, designating critical habitat, developing protective regulations for threatened species, and consulting on federal actions.

The Endangered Species Act has been overwhelmingly successful in preventing the extinction of over 99% of the species it has protected over its 50-year history. Throughout the year, the Departments of the Interior and Commerce will celebrate these successes and highlight the continued importance of this statute in addressing today’s environmental challenges, promoting the recovery of wild plants and animals, and conserving the habitats upon which they depend.

The proposed rules will be subject to public review and comment, and all comments will be carefully considered before a final rule is published.

The agencies encourage any interested parties to provide input and substantive comments on each of the three separate proposed rules during the 60-day public comment period from June 22, 2023 to Aug. 21, 2023. The notice will be available in the Federal Register on June 22, 2023. The proposed rules will be placed on public inspection on June 21, 2023 at
