Captured July 27, 2007.Proposes action to develop more quickly late-successional habitat characteristics used by northern spotted owls and marbled murrelets, to reduce erosion and landslide risks, improve aquatic habitat, and to provide a commercial product for the economy. Analyzes alternatives thinning 30 to 80 year old (mid-seral) forests to develop late-successional habitat and improve riparian habitat, as well as selling wood for commercial purposes. Watershed enhancements would improve 52 miles and decommission 4 miles of road to reduce sedimentation, would remove, replace or upgrade between 22 and 30 culverts that are barriers to fish passage, would enhance approximately 15 miles of stream habitat through placement of logs or boulders, and would cut, girdle, and/or remove hardwoods to accelerate conifer development in riparian areas.en-USWatershed restoration -- Oregon -- Roseburg RegionFish habitat improvement -- Oregon -- Roseburg RegionLogging -- Oregon -- Roseburg RegionForest thinning -- Oregon -- Roseburg RegionPublic lands -- Oregon -- Roseburg RegionUpper Umpqua Watershed plan environmental assessmentEnvironmental assessment: Upper Umpqua Watershed planOther
