    Curtis timber sale decision notice and finding of no significant impact
    (2008-09-09) Umpqua National Forest (Agency : U.S.)
    Announces decision choosing Alternative 4 of project EA, initiating commercial thinning of about 1,508 acres of managed and natural stands (second growth) using ground-based or skyline logging systems in the Matrix land allocation generating approximately 12.7 million board feet of timber. Thinned acres will include about 825 acres of off-site ponderosa pine harvesting or girdling to remove non-localized conifers and to restore to native plant communities. Also includes treating activity created fuels on about 878 acres by underburning, grapple or excavator piling (with machines remaining on pre-designated skid trails), lopping and scattering, chipping, jackpot burning, or handpiling and burning, and construction and reconstruction of roads.

    Kincaide's lupine habitat restoration project decision memo
    (2008-09) Umpqua National Forest (Agency : U.S.)
    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.
