Fish & wildlife

We work to protect fish, wildlife, and habitat resources during construction, maintenance, and operation of the state transportation system. The Washington State Department of Transportation (WSDOT) implements standard practices and training, supports wildlife research, and provides additional tools to support this goal.

Policies & procedures

Use the standard practices and protocols developed by WSDOT for their biologists, consultants, and maintenance crews to limit impacts to fish, wildlife, and habitat while following federal and state regulations.

  • Read Chapter 436: Fish, Wildlife, & Vegetation of our Environmental Manual for information on the policies on fish, wildlife, and vegetation.
Learn how wildlife research contributes to the protection of fish, wildlife, and habitat resources during the operation of the state transportation system. WSDOT supports research on the relationships between wildlife and habitat and the transportation system. This includes statewide habitat connectivity analysis, ranking the suitability of existing bridges and culverts for providing wildlife passage, landscape permeability for large carnivores, and wildlife crossings and collisions analysis
Learn about the carcass removal database, where WSDOT tracks wildlife carcasses removed by maintenance staff. Tracking wildlife killed on highways helps identify wildlife collision problem areas, helping WSDOT plan and implement corrective actions to reduce wildlife mortalities and improve highway safety.
To meet the standards, consultants must demonstrate their ability to write BAs through education and experience requirements. You must also attend a training course and achieve a passing score on the exam.
