Temporary Stabilization Specification Improvements
Seed variety performance data for establishing temporary vegetative cover was collected at four Illinois locations at four planting seasons. Current Illinois Department of Transportation (IDOT) standard specifications call for a mixture of perennial rye and spring oats for temporary vegetative cover, with no variation for time of year or site conditions. That mixture has demonstrated some success; however, for every location and time of year, this study identified at least one seed variety that demonstrated performance superior to the specified mix. Temporary seeding specifications currently employed by nearby states were reviewed and compared with Illinois’ specifications. In addition to seed variety, the effectiveness of seed bed preparation using a power rake and the effectiveness of straw-mat and loose wheat-straw mulching methods were investigated. Based on the observed results, the research team has proposed modifying temporary seeding recommendations to reflect seeding date and site location. Adoption of these research-based temporary seeding specifications will likely result in improved temporary vegetative cover establishment, reduced erosion, and improved water quality.
