Little Topashaw Creek - Use of willow cuttings for riparian zone rehabilitation - Soaking |
Results from the first growing season clearly indicated that soaking enhanced willow post survival. Percent survival of soaked posts (64%) was significantly greater than survival of unsoaked posts (53%) six weeks after planting, ten weeks after planting, and 34 weeks after planting. Study plots with highest survival rates (81% - 94%) were characterized by moderate elevation above the stream and soils containing moderate amounts of sand. Lowest survival (0% - 31%) generally occurred in plots located at lower elevations. Soils at low survival plots ranged from sandy to finer-grained. Plots where soaked posts had at least 25% higher survival rates than unsoaked posts were generally characterized by higher elevation and moderate to high sand content. Back TD <> |
