Watershed Responses to Disturbance

As climate change intensifies, natural disturbances are dramatically reshaping ecosystems. This is especially prevalent across the western United States, particularly in vulnerable mountain regions with complex landscapes and tightly linked land-water systems. In this study, we examine how disturbances—whether sudden events like wildfires and bark beetle outbreaks, or ongoing pressures like reduced snowpack and gradual vegetation changes—affect the chemistry and flow of streams in temperate montane watersheds.

Stream Chemistry Response to Fire

Wildfires are increasingly affecting the wet forests of the Pacific Northwest, a trend expected to intensify with climate change. These fires disrupt water quality and streamflow, threatening aquatic ecosystems and drinking water supplies. While the impacts of high-severity wildfires on streams are relatively well-studied, less is known about low- and mixed-severity fires. To address this, researchers studied the mixed-severity 2020 Holiday Farm Fire in two watersheds within the H.J. Andrews Experimental Forest.
