Ecosystems Northwest was established in 1994 in Corvallis, Oregon and relocated to Mount Shasta, California in 1999. The firm was founded by Kim Gerard Mattson to pursue independent, applied ecological work outside the constraints of institutional research.

Kim holds a Ph.D. in ecology and has conducted foundational research on forests, soils, and ecosystem carbon dynamics. His work bridges basic science and real-world management, with particular depth in carbon cycling, forest offset protocols, and Pacific Northwest aquatic systems.

Ecosystems Northwest takes on projects that require rigorous science delivered in a form that is useful to land managers, regulatory agencies, communities, and private landowners. The firm draws on a network of experienced field scientists who join on a project-by-project basis, keeping the operation nimble and expertise-matched to each engagement.

"Ecosystems Northwest can bring in the best options to help you craft your environmental solutions."
