The Budget for Deciding What's Endangered Fell 66%. A Reorg Line Alone Is Worth 24 of It.

Summary

Fish and Wildlife's Listing program — the office that decides which species qualify for Endangered Species Act protection — falls from $22.0 million to a requested $7.4 million in two budget cycles, as agency staff overall drops 18%. The same request would move $178.0 million of NOAA's marine-species duties into the identical account.

Somewhere inside the U.S. Fish and Wildlife Service there is a single budget line whose entire job is to decide whether a plant or animal qualifies for Endangered Species Act protection. It is called, plainly, "Listing." In the agency's own FY2027 congressional budget justification, that line falls from $22.0 million in FY2025 to $14.0 million enacted for FY2026 to a requested $7.4 million for FY2027 — a 66% cut in two budget cycles, with the staff assigned to it falling from 100 to 60 to 27. Zero species have been added to the endangered list in the second Trump administration, compared with 22 in the first. The same budget document that guts Listing also proposes folding $178.0 million of marine-species work into the identical Ecological Services account — a transfer large enough, on paper, to make the account's bottom line look like it grew.

The line that decides, three budgets in a row

Listing is not conservation spending in the usual sense — it doesn't restore habitat or breed a species back from the brink. It funds the biologists and reviewers who read petitions, run the five-factor legal test in the statute, and issue the findings that make everything else — recovery funding, habitat protection, take permits — possible. Cut that line and nothing downstream starts.

FY2026 (enacted)$14.0M60 FTE, -36% vs FY2025
FY2027 (requested)$7.4M27 FTE, -66% vs FY2025

The FY2025-to-FY2026 cut alone — $22.0 million to $14.0 million — is a 36% reduction, the same figure independently cited by the Center for Biological Diversity and Defenders of Wildlife in an April 2026 letter urging Congress to raise the Service's broader endangered-species conservation budget from $299 million to $870 million. The FY2027 request cuts the same line by another 47%, on top of that. Staff assigned to Listing falls in step: 100 in FY2025, 60 in FY2026, 27 requested for FY2027 — a 73% reduction in the people doing the work, tracking almost exactly the 66% cut in the money that pays them.

Meanwhile, the Service's own Candidate Notice of Review — published October 31, 2025 (90 FR 48912) — puts the formal candidate count, species has already determined warrant listing but hasn't yet proposed, at 16 as of September 30, 2024. Outside trackers, working from 's own species database, count a much larger population of roughly 400 species with petitions pending some stage of review, per Daily Montanan reporting sourced to Center for Biological Diversity and data — the gap between the two counts is itself a measure of how much of the process happens before a species ever reaches the formal "candidate" stage the Listing program is funded to move through.

Where the rest of the money went

The FY2027 request's total for the whole Ecological Services activity — $427.96 million — is actually larger than FY2026's $277.53 million, a 54% nominal increase. Read the budget document's own program breakdown and the reason is specific: it proposes consolidating National Marine Fisheries Service's marine-mammal and marine-species ESA/MMPA duties into 's Ecological Services account, adding $178.0 million of entirely new money that has nothing to do with 's existing terrestrial and freshwater listing backlog.

Line up the five program elements and Listing — the function that actually puts a species on or off the list — is the smallest of the five, at $7.4 million against a $178.0 million transfer that doesn't fund a single new listing decision. The transfer alone is worth more than 24 Listing programs. It is real money for a real function — marine mammal and marine species conservation is not manufactured work — but it is also money that, folded into the same account, makes the section of the budget request that guts the listing pipeline read, in the topline, as growth.

The workforce doing what's left

The Listing cut sits inside a larger agency contraction. employed 9,957 people in 2024; by the end of May 2025 that had fallen to 8,179 — an 18% loss, roughly 1,778 positions, according to 'd internal agency data obtained by the Center for Biological Diversity and cited independently by Sens. Jack Reed and Sheldon Whitehouse in a December 2025 letter, and separately reported (also "at least 18%") by E&E News. More than 500 of the departures were biologists — the job category that writes the species status assessments the Listing program depends on.

"Every lost biologist is a lost lifeline for an endangered animal or plant," Stephanie Kurose of the Center for Biological Diversity said in the April 2026 letter. The Service's own budget document doesn't dispute the staffing math — it proposes to keep cutting it, along with the dollars, for the one program whose entire function is to say which species are running out of time.

The takeaway

  • The Listing budget was cut 66% in two years — $22.0 million to a requested $7.4 million — with staff falling 73%, from 100 to 27. This is 's own figure, from its own budget justification.
  • A single accounting move — folding $178.0 million of marine duties into the same account — makes the total Ecological Services request look 54% larger, while the part that actually lists species keeps shrinking.
  • Agencywide, lost 18% of its staff — 9,957 to 8,179 — between 2024 and May 2025, over 500 of them biologists, the exact job category the Listing program runs on.
  • Zero species have been added to the endangered list in the second Trump term, against 22 in the first — a fact independent of any single budget line, but consistent with what these budget lines fund.

Budget figures are fixed fiscal-year appropriations and requests as published; staffing counts are point-in-time snapshots (2024 and end of May 2025) and will have moved further by the time you read this.
