Situation - 2 Skid Trail Rehabilitation: Skid trails to remove logs from cutting units were developed by 

 cats and skidders during past timber harvest activities. Most of the skid trails developed in the past 20 

 years were waterbarred when the skidding was completed. The waterbarring disperses the water 

 before it is concentrated into a defined flow that causes erosion. Some of the earlier skid trails and/or 

 the log landings where the skid trails converge have had very small streams {skid-streams) develop on 

 them due to soil compaction and intercepted groundwater. These small skid-streams typically only run 

 water during snowmelt or high intensity rainstorms, however, this does increase the peak flow response 

 within the basin. The majority of these skid-streams have eroded away the fine textured soils within 

 their stream bottoms and bank, causing them to be well armored by cobbles and stones, and typically 

 well vegetated. Going back and constructing waterbars at this time would disturb the established 

 vegetation and expose soil to be potentially eroded. Refer to photograph - 8 for an example of a skid- 

 stream. 



However, there are some sites that fine soil materials are still being eroded from. On these sites there 

 are several proposed rehabilitation actions to be done singularly or in combination. The primary work 

 includes dispersing water where it has concentrated on skid trails and landings through actions that 

 may include: the construction of waterbars, the planting of shrubs, the planting of grass, the placement 

 of rock armoring, and/or the construction of small check dams with pieces of wood. Where streams 

 had been rerouted from their natural channel, work can be done to try to return the stream to its 

 historical drainage path.
