Provides funding authority and spending rules for the Department of the Interior and related agencies for fiscal year 2026 and imposes government‑wide spending, reporting, procurement, and program rules. It creates or adjusts several specific program authorities (for example, inspection fees, long‑term wild horse and burro contracts, and salmon hatchery marking), restricts some uses of funds, requires new reports and transparency on land/conservation actions, and authorizes amounts to be appropriated from the Treasury for FY2026.

Sets agency-level limits and deadlines (including availability of funds, fee payment timing, and requirements to update certain federal records to use the name “Denali”), adds centralized reporting and congressional notification requirements for conservation/restoration spending decisions, places restrictions on use of funds for specified activities (e.g., lobbying, certain leasing or mining patent processing), and applies Buy American iron/steel requirements to specified drinking‑water projects. Two sections (EPA and Related Agencies) were not provided in the upload and therefore their detailed provisions could not be summarized here.
