what we do

Biological Sciences & ESA

Delivering pragmatic, science-based strategies to benefit our environment

Our team of biologists, ecologists, and environmental planners blend practical experience with scientific understanding to develop solutions that work. Our approach includes developing a range of strategies to manage risks, building on best practices, and streamlining the permitting and mitigation process. We help our clients comply with the Endangered Species Act (ESA) and achieve policy goals and directives, reduce regulatory compliance delays, reduce risk, improve stakeholder relationships, and improve the health and resiliency of our environment.

Inland Avian Predation Management Plan | Parametrix
Inland Avian Predation Management Plan
​​Columbia River Basin, Washington
Client: ​U.S. Army Corps of Engineers, Walla Walla District
Partner: Normandeau Associates

Parametrix prepared a Biological Assessment and an Environmental Assessment to collaboratively assist the Corps and partner agencies—Bonneville Power Administration, Bureau of Reclamation—in determining methods to protect listed fish from avian predators (such as Capian Terns) along inland areas of the Columbia River. In addition to supporting the overall management plan, the Environmental Assessment satisfies all NEPA requirements and serves as a decision-making document for determining actions that are environmentally acceptable and economically justified.
