Description :
Seven small watersheds with various levels of land disturbance (burned, post-fire salvage logged, unburned) were instrumented and monitored for 4 years to measure stream discharge, sediment concentration, and sediment yields for a range of dominant flow periods characteristic of the region (baseflow, spring melt, and stormflow). Results and discussion. Because of increases in wilfire frequency and severity over recent decades, understanding the rage of impacts from both wildfire and post-disturbance management strategies such as salvage logging is likely to become increasingly important for land managers.
