- Title
The Effects of Wildfires on Aquatic Ecosystems.
- Authors
WUERTHNER, GEORGE
- Abstract
WILDFIRE, STREAM CHANNEL ALTERNATIONS, AND SEDIMENTATION Fire-induced vegetation loss can also affect stream flow and timing. After the fire, subsequent heavy summer thunderstorms contributed to major changes in stream channel combined with significant sediment flow that initially led to a decline in aquatic insects and fish. When a watershed burns, the loss of plant cover and subsequent changes in sediment flow, changes in water temperature, changes in debris flow, and the release of nutrients into the system often alter streams. Indeed, a recent study of wildfire effects on trout in the Rio Grande found that initially, there was some fish kill due to post-fire sediment loads, but stream conditions had stabilized within three years.
