Streams cannot be filled with logs and dirt to build a crossing. If equipment fords a stream channel it must go straight across and the stream bottom should be hard or graveled. Stream banks should not be disturbed at a stream crossing. A buffer of grass and trees should be left along streams to trap sediments before they enter the water. If the slope is steep or erosion results then more must be done to stop any mud from entering the water.
Trees shade a stream and maintain normal temperature.
Clearing the natural vegetation along a streamside can lead to streambank destabilization and severe erosion. There should be no use of skidders or other logging equipment in streams or in an SMZ or in streams or drainages. Streams and drainages should not be used as skid trails. Skid trails from equipment that drags logs to a log landing should be gradual and not allow any erosion. Debris from logging should not be left in the stream.
