Surface erosion, sedimentation, and shallow-seated slope failures in Idaho present a significant challenge to roadway construction and maintenance. Soil losses from such slopes deplete an important natural resource, induce excessive maintenance such as ditch and culvert clean-outs, and may cause adverse effects on the quality of surface waters in the state. The proposed research will help Idaho Transportation Dept. address specific revegetation site requirements and determine the most effective ways to provide for the long term establishment of desirable perennial vegetation to reduce surface erosion and sedimentation.
The goal of this project is to investigate revegetation techniques for erosion control, sediment reduction, and slope stability and to provide training for ITD personnel responsible for design, construction, maintenance, and environment.
Expected outcomes were
- Two in-depth training modules were developed for in-house training for ITD personnel. Revisions to Roadside Revegetation Guidebook were completed, and
- The publication, Application of Various Nurse Crop Treatments for Establishment of Long-Lived Perennials 2000--2001, was delivered to ITD.
