Candidate Species Conservation Program

Columbia spotted frog
Candidate species are plants and animals for which the Service has sufficient information on their biological status and threats to propose them as endangered or threatened under the Endangered Species Act, but for which development of a listing regulation is precluded by other higher priority listing activities.

The Candidate Conservation Program provides a means for conserving these species. Early conservation preserves management options, minimizes the cost of recovery, and reduces the potential for restrictive land use policies in the future. Effective candidate conservation may reverse the species' decline, ultimately eliminating the need for ESA protection.

Candidate Species and the Endangered Species Act

Candidate Notice of Review

The Service periodically publishes an updated Candidate Notice of Review primarily to solicit new information on the status of candidate species and threats to their survival. Service biologists rely on a variety of sources to determine whether a species may require listing under the Act, including contributions from private, university and government scientists and other citizens, as well as local, state and federal land management and planning agencies.

There are currently 16 candidate species which occur within the geographic boundary of the Nevada Fish & Wildlife Office. The Nevada Fish & Wildlife Office geographic responsibility boundary includes some portions of California along the Nevada border. To learn more about these species, click on the links provided.

Conservation Agreements and Strategies

Conservation agreements and strategies (CAS) are developed as a collaborative and cooperative effort among local, state, federal resource agencies, and private sector partners to expedite the implementation of conservation measures needed to ensure the continued existence and recovery of a species.
