Does the October 2026 State Wildlife Action Plan revision add any species to the Endangered Species Act list?

No. The revision amends the State Wildlife Grants guidance, not the ESA. It changes how states document Species of Greatest Conservation Need, not which species are federally listed.

What the October 2026 state wildlife action revision means for at-risk

Updated 21 October 2026

The revision, published on 14 October 2026 by the United States Fish and Wildlife Service under the authority of the State Wildlife Grants programme at 16 U.S.C. § 669c, replaces the 2015 State Wildlife Action Plan guidance with a binding template that states must follow when they next revise a plan. Service Director Brian N. Latimer signed the document, titled State Wildlife Action Plan Guidance, Revision 4 (2026) , and it appears at 91 FR 60555. The revision does not change the list of threatened or endangered species under the Endangered Species Act. It does change how states must inventory, map, and report on the Species of Greatest Conservation Need, or SGCN, that sit one tier below federal listing and that, in most states, include more animals than the federal lists do. For species that are already listed, the revision does little. For the far larger group that is not, it does a great deal. The plan now obliges states to publish the underlying occurrence records, to use a uniform map standard, and to commit to measurable outcomes in a way that the 2015 guidance did not. That sounds bureaucratic, and it is. It is also the part of United States wildlife law that touches the most individual animals each year, and it is the part that gets the least attention.

The four new elements, nine through twelve

Revision 4 keeps the eight elements in place since 2005 and layers four more on top. Element nine asks every state to publish an occurrence record layer for its SGCN, drawn from museum vouchers, state survey data, and the Biotics database, in a form that other agencies can load. Element ten sets the Biotics 5 standard as the common mapping language, replacing the patchwork of state schema that the 2015 guidance allowed. Element eleven demands a measurable outcome for every conservation action, written so that a reader can tell whether it worked, with a target value, a method, and a time horizon attached to each action so that failure is visible in the same way as success. Element twelve requires a public facing dashboard that shows the state, the species, the action, and the outcome in one place, refreshed on a cycle the Service sets in Appendix D and backed by the same occurrence layer that element nine compels states to publish. Taken together, the four new elements push the plan from a document states write once into a record states keep, and they convert the plan from a narrative into a dataset that other agencies, other states, and the public can query. A worked example sits in Appendix E, where a state freshwater mussel team is shown moving from a 2015 style paragraph to a 2026 style row in the dashboard, with a count of occupied reaches, a target for the next revision cycle, and a link to the Biotics 5 feature class that holds the records.

What changes for listed species and for the far larger group that is not

For species already listed under the Endangered Species Act, the revision does little. The ESA does the work, and Revision 4 leaves the federal list alone. The federal list is short, the rules around it are old, and the obligations it creates are well understood by the agencies that carry them out. For the far larger group that sits one tier below, the SGCN tier, the revision does a great deal, and that is the point. The 2022 National SGCN Review puts the list at around 12,000 species across the states and territories, and the bulk of those species are invertebrates and plants that the ESA reaches only intermittently, because federal listing is slow, expensive, and reserved for the most acute cases. The SGCN tier is where state agencies do most of their daily work, and it is the tier that the 2015 guidance left in a soft focus, with each state free to define its own map standard and free to keep its occurrence data on a server that no one outside the agency could read. The new template gives those species a consistent map, a published record, and a measured outcome, and it does so by tying the twelve elements to the State Wildlife Grants award rather than to a new regulation. A state biologist in 2029 will be able to pull the same data layer that a federal reviewer pulls, and a member of the public will be able to read the same dashboard. A second concrete gain is that the Biotics 5 schema in Appendix D forces a shared vocabulary for habitat codes, threat codes, and action codes, which means a state can compare its own plan to its neighbour's plan without a manual translation, and a service reviewer can compare fifty plans at once. The change is procedural, and the gain is concrete.

Timing, grants, and what to watch next

Plans adopted in 2027 will be reviewed against a transitional checklist published as Appendix C to Revision 4, which lists the four new elements in priority order and gives a state a pass on element twelve if it can show a working draft of the dashboard at the point of adoption. Plans adopted in 2028 and later must meet the full template, with no transitional relief, and the Service has signalled in the preamble that a state that misses the dashboard requirement will be treated as out of compliance with the grant. The State Wildlife Grants formula and match are unchanged, but compliance with the new template will, from fiscal year 2028 awards onward, be a condition of the grant, and the condition is enforced through the award letter rather than through a new rule. That is the lever. A state that wants the money agrees to the terms, and the terms are now the twelve elements, the Biotics 5 schema in Appendix D, and the worked examples in Appendix E. Two practical points follow. First, states that have not yet started a revision should read Appendix E early, because the worked examples for the freshwater mussel, the crayfish, the migratory bird, the bat, and the grassland plant are the most concrete guide to element eleven and the only place in the revision where a state can see, line by line, what a measurable outcome looks like on paper. Second, state records officers should plan for the public facing dashboard in element twelve, because a dashboard that is built at the end of a revision cycle is a dashboard that ships late, and the data feeds from element nine and the schema in element ten both need to be stable before the dashboard can be wired up. The legal weight of Revision 4 is contractual, not regulatory, which is why the publication of the occurrence layer and the dashboard matters more than the text of the plan itself, and which is why a state that treats the revision as a writing task will find itself out of compliance at the moment the award officer opens the dashboard URL and finds a 404.

Quick answers

Does the October 2026 State Wildlife Action Plan revision add any species to the Endangered Species Act list?: No. The revision amends the State Wildlife Grants guidance, not the ESA. It changes how states document Species of Greatest Conservation Need, not which species are federally listed.
When do state plans have to comply with the new twelve-element template?: Plans adopted in 2028 and after must meet the full template. Plans adopted in 2027 will be reviewed against a transitional checklist published alongside the revision.
Are State Wildlife Grants affected?: The formula and match are unchanged. Compliance with the new template will, from fiscal year 2028 awards, be a condition of the grant.
