Aquatic Biodiversity Responses to Wildfire in Oregon

Wildfires change the structure and function of forests and may influence their ability to support biodiversity and cool, clean water. In 2020, multiple megafires spread through western Oregon and burned public and private forestland, often at high severity. To understand the effects of these wildfires on aquatic ecosystems, NCASI, PNW Research Station, Weyerhaeuser Company, and numerous other partners sampled aquatic biodiversity across 25 watersheds.
