Should federal agencies be required to act faster on endangered species protections?
The Center for Biological Diversity, Alabama Rivers Alliance and Black Warrior Riverkeeper filed a notice of intent to sue U.S. Fish and Wildlife Service on Thursday. The groups say the agency failed to meet a 90-day deadline to determine whether protections may be warranted for the Birmingham darter, petitioned for in November 2025.
Why it matters
The Birmingham darter exists in only six known populations in the Valley Creek system in Jefferson County, and the groups argue its limited range makes endangered status clear. The dispute could determine whether habitat threatened by industrial pollution, poor water quality and urban growth in Alabama receives federal protection.
The record shows a 90-day federal review deadline that was missed and only six known Birmingham darter populations, all in the Valley Creek system. It remains unclear whether the agency will issue a determination within the 60 days it has to respond to the notice.
The players
U.S. Fish and Wildlife Service
The federal agency responsible for administering the Endangered Species Act for freshwater fish and wildlife, including decisions on whether species qualify for protection.
Center for Biological Diversity
A nonprofit conservation organization that frequently litigates to secure Endangered Species Act protections for imperiled plants and animals.
The details
The groups filed the notice after submitting a protection petition in November 2025 and cite the agency's failure to act. The fish faces threats from industrial pollution, poor water quality and increasing urbanization, and the Northern Beltline highway project around Birmingham and a Project Marvel hyperscale data center near Bessemer are proposed developments affecting it.
Timeline
November 2025: Groups submitted the Endangered Species Act petition for Birmingham darters.
90 days after petition: Fish and Wildlife Service deadline to decide whether protections may be warranted passed.
Thursday, November 2026: Conservation groups filed notice of intent to sue the agency.
60 days after notice: Agency deadline to respond or face legal action.
Legal Context
The dispute turns on the Endangered Species Act's requirement that the Fish and Wildlife Service issue a 90-day finding on whether a petition presents substantial information warranting a status review. Missed deadlines like this one have historically led conservation groups to file notices of intent to sue under the Act's citizen-suit provision.
Whether the Birmingham darter receives federal protection could affect how development projects such as the Northern Beltline and the Bessemer data center proceed in the Valley Creek area. Residents and businesses near the affected waterways may face new review requirements depending on the agency's decision.
The takeaway
The case shows how Endangered Species Act deadlines can become the central point of a dispute, since a missed federal timeline is what triggered the threatened lawsuit. Readers following Alabama development projects should watch whether the agency responds within the 60-day window.
What happens next
The Fish and Wildlife Service has 60 days from the notice to respond or face legal action from the conservation groups.
