This bill designates the High Plains Research Station and Arboretum in Laramie County as a state historic site, managed by the Department of State Parks and Cultural Resources. It mandates the development of a strategic master plan for the site's preservation and operation, allowing the department to enter into agreements with various entities for its administration. The bill also authorizes the department to impose fees beyond standard permit fees to cover expenses related to the site's maintenance and operations, with collected fees deposited into the state parks account.

Additionally, the bill appropriates $3,338,756 from the general fund for the High Plains Research Station and Arboretum, which must be used exclusively for the site until June 30, 2026. The appropriation will be reduced by any amount spent from previously allocated funds for the same purpose. The department is required to initiate the strategic master plan within one year of the bill's effective date and report its progress to the relevant legislative committee by October 1, 2026. The act takes effect immediately upon completion of the necessary legislative processes.
