Captured March 18, 2009.The proposed action is to reduce conifer encroachment by commercial thinning on approximately 3 acres. No trees over 20" DBH will be cut. Trees up to 20 inches in diameter would be removed to create an opening dominated by California black oak and only a few conifers. The primary prescription is to retain 10-12 dominant conifers with crown ratios greater than 40%. Douglas-fir and ponderosa pine are the preferred species. In all thinning areas California black oaks, Oregon white oaks, and Pacific madrone will be left standing. The treatments would occur alongside the existing Kincaid's lupine population, but would not disturb this area.en-USLupines -- Oregon -- Umpqua National ForestEndangered plants -- Oregon -- Umpqua National ForestLogging -- Oregon -- Umpqua National ForestForest thinning -- Oregon -- Umpqua National ForestForest management -- Oregon -- Umpqua National ForestOther
