About this program

The Department of the Interior Fish and Wildlife Service awards grants under Candidate Species Conservation (CFDA 15.660) to support proactive conservation of candidate and at-risk wildlife and plant species before they warrant federal listing under the Endangered Species Act. The most recent award was issued January 1, 2026, with a current open solicitation (F25AS00228) due September 30, 2025.

The program has funded 267 grants totaling $24.6 million in federal dollars obligated since 2008, with recent activity averaging 20–27 awards per year over the past five years, though 2026 activity appears limited to one award to date. Awards are predominantly Cooperative Agreements (70 percent, 187 awards) paired with Project Grants (30 percent, 80 awards). Funding concentration is substantial: the Department of the Interior Fish and Wildlife Service and its regional offices account for 88 percent of awards by count, with Region 8 leading at $8.7 million federal dollars obligated across 43 awards, followed by Region 1 at $4.1 million across 51 awards. The Department of the Navy Installations Command has contributed $2.2 million on a single award, reflecting occasional non-FWS participation. Combined federal and non-federal dollars obligated total $25.3 million, indicating modest recipient cost-share or matching beyond the federal contribution.

Recent awards span native seed collection and propagation for post-wildfire sagebrush habitat restoration in Nevada and the Pacific Northwest, genetic and population surveys for candidate species including little brown bats, pinyon jays, and western ridged mussels, captive breeding and reintroduction programs for reptiles and land snails, and habitat monitoring and management for species under ESA review. Typical awards range from $15,000 to $765,000, with infrastructure and multi-year projects occupying the upper end. The Great Basin Institute, state fish and wildlife agencies, tribal governments, universities, and conservation nonprofits dominate the recipient base.

The current open opportunity (F25AS00228) accepts applications from federal agencies excluded, all other entity types including state and local governments, tribes, nonprofits, higher education, and individuals through September 30, 2025. Projects must address candidate species listed in FWS annual assessments or at-risk species in conservation plans or spotlight species action plans. Funding must be spent within three years of award. Regional field office contacts direct applicants toward high-priority conservation needs; early coordination with the appropriate FWS Regional and Field Office is advised per program guidance.
