Assessing soil erosion and its potential to degrade water quality

Author(s): Younie, Michael (Ministry of Environment)
Subject: Integrated resource management
Series: Forest Investment Account (FIA) - Forest Science Program


Soil erosion and sedimentation from forest roads can adversely impact drinking water quality as well as the water quality upon which aquatic life is dependent. A recent audit (Younie 1999) of forest roads indicated that the majority of soil erosion field assessments were not being completed when required by the Forest Practices Code of BC Act. The lack of completion was attributable to a lack of guidance around soil erosion field assessments.
The objectives of this project were (i) to examine the critical factors for assessing soil erosion and sedimentation from forest roads in the coastal BC area, (ii) to explore the strategies and techniques for mitigating soil erosion and sedimentation that could be reasonably expected to be incorporated into road design prescriptions and (iii) to develop extension products and disseminate this information to personnel involved with designing and constructing forest roads in coastal BC. Forest Renewal BC funding was secured to address objectives (i) and (ii) while Forestry Innovation Investment funds were secured to address the third objective.
A hypertext presentation regarding all aspects of assessing soil erosion and sedimentation in coastal BC was produced. The presentation also included information on coastal hydrology and mitigation techniques. Two hundred copies of the CD were produced and will be distributed free of charge to personnel involved with designing and constructing forest roads in coastal BC. Articles and other presentations were also produced to raise awareness of soil erosion issues. It is expected that this product will form one of the tools available to practitioners in the new “results-based” regime.
