OK HB1822

Requires Oklahoma Department of Transportation to establish and implement a program for systematic identification, removal, and management of invasive woody species within rights-of-way under its jurisdiction.

Program must include surveys to identify invasive species presence and extent, development of a prioritized eradication plan, use of best management practices minimizing harm to native vegetation and soil erosion, monitoring to prevent reestablishment, and collaboration with local, state, and federal agencies and nongovernmental organizations.

Becomes effective November 1, 2025.
