Removal of snags or large wood may re-suspend sediments into the stream. 

Removal of shade-producing canopy will lead to an increase in surface water temperature, especially during low flows.

Depending on species, availability of food sources may be lost with removal of in-stream materials.

Depending on species, availability of cover will be lost with removal of in-stream materials.

Clearing of bank vegetation and in-stream wood generally increases flow velocities and decreases slow-water habitat complexity.

Removing woody debris from stream reduces aquatic habitat.
