Slide show - Road Decommisioning

  • logging road Logging roads are the primary source of sediment delivery and landscape instability in forestry activities. Roads interrupt natural drainage, and when located on steep slopes have the potential to cause landslides and mass wasting.
  • wetland Prior to the mid 1980’s little attention was given to the environmental impacts of building roads and they were frequently built in wetlands, along riparian corridors, and on unstable slopes.
  • stream Roads left in the landscape have huge impacts long after logging activities cease. Culverts can become clogged creating washouts that deliver sediment to streams.
  • unstable fill Unstable fill on side slopes can fail, causing landslides and debris delivery to streams and wetlands. This old road failed near the large boulder.
  • heavy equipment Decommissioning requires heavy equipment and involves removing culverts and road fill. Streams are protected during the work by diverting them to bypass pipes and pumping the water around the work zone.
  • stream channel Stream channels are restored and large rock and woody debris are placed along and within the channel to provide habitat complexity. Above the stream, waterbars or large dips are cut to prevent runoff from entering the stream.
  • stream crossing This stream crossing was recently restored. Straw with grass seed is placed over all exposed soil to reduce erosion and encourage revegetation.
  • stream before restoration This old road was built within the stream bed and the stream was placed in a ditch.
  • stream after restoration This is the same section of stream after restoration. The road fill was removed, the stream channel restored with rounded "fish-friendly" rock, and the flood plain restored.
  • road being removed Where roads were built through wetlands, the entire road bed is removed and the wetland is restored. This road is in the process of being removed.
  • road bed reshaped Where road fill does not need to be removed, the road bed is reshaped to improve drainage and reduce the potential for future failures. Waterbars are cut across the road to encourage runoff from the remaining road bed.
  • before & after road decommissioning The top photo shows a road adjacent to and interfering with a wetland. The bottom photo shows the same location immediately after road decommissioning.
