Item Open Access 2008-2012 Pre-commercial thinning decision memo(2008-01-30) Umpqua National Forest (Agency : U.S.)Announces decision to approve pre-commercial thinning projects. The purpose of this project is to reduce stand densities, prolong early seral stage stand structure, increase growth rate of dominant trees, and enhance species diversity. Associated hazardous fuels reduction would reduce fuel bed depths along major roads and improve condition class. A total of 3761 acres of plantations have been identified as potentially benefiting from thinning under this proposal.Item Open Access 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.Item Open Access Curtis timber sale project environmental assessment(2008-06) Umpqua National Forest (Agency : U.S.)Proposes commercial thinning of about 1,508 acres of managed plantations and fire-regenerated second-growth using ground-based or skyline logging systems in the Matrix land allocation generating approximately 12.5 million board feet of timber. Thinned acres will include about 825 acres of off-site ponderosa pine 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 constructing and reconstructing roads.Item Open Access D-Bug hazard reduction timber sale project draft environmental impact statement(2009-03) Umpqua National Forest (Agency : U.S.)Proposes project modifying pine beetle habitat conditions in stands containing lodgepole to reduce potential infestation by mountain pine beetles. Includes variable density commercial thinning of 3,165 acres in lodgepole pine stands (leaving 20-70 TPA), thinning 1,145 acres of lodgepole-mixed conifer (leaving 50-200 TPA), and thinning of 2,247 acres in mixed conifer stands (leaving 50-90 TPA) and non-commercial removal of fuels on about 2,026 acres by pre-commercial thinning, mastication, whip felling, chipping, and piling and burning of slash.Item Open Access Doris thin timber sale project decision notice and finding of no significant impact(2008-05-08) Umpqua National Forest (Agency : U.S.)Announces decision initiating project, including: Commercial thinning 1000 acres of timber stands using helicopter, groundbased, and skyline logging systems in both the matrix and riparian reserve land allocations to generate about 13.4 million board feet of timber. No thinning would occur on 282 acres of riparian or unique habitat areas, or where protection of rare plant species and soils is a concern. Treating activity-created fuels on 609 of the thinned acres by underburning, machine piling, and hand pile and burning. Road reconstruction work includes replacement of twenty six 18-inch ditch relief culverts along with three new ditch relief culverts and six stream crossing culverts. Road grading and ditch line maintenance would occur on 38 miles of existing road. Replacement of 11 stream crossing culverts will take place.Item Open Access Doris thin timber sale project environmental assessment(2008-04) Umpqua National Forest (Agency : U.S.)Proposed action includes: Of the 1,282 acre planning area, commercial thinning 1000 acres of timber stands using helicopter, ground-based, and skyline logging systems in both the matrix and riparian reserve land allocations to generate about 13.4 million board feet of timber. No thinning would occur on 282 acres of riparian or unique habitat areas, or where protection of rare plant species and soils is a concern. Treating activity-created fuels on 609 of the thinned acres by underburning, machine piling, and hand pile and burning. Road reconstruction work includes replacement of twenty six 18-inch ditch relief culverts along with three new ditch relief culverts and six stream crossing culverts.

Also includes treating activity created fuels on 1,171 acres by underburning, crushing, machine piling, pruning/chipping, or handpile burning, and construction and reconstruction of roads.Item Open Access Emile timber sale environmental assessment(2008-06) Umpqua National Forest (Agency : U.S.)Proposes commercial thinning of about 1,835 acres of timber stands using helicopter, ground-based, and skyline logging systems in AMA, Matrix and Riparian Reserve land allocations generating about 25 million board feet of timber. Also includes treating activity created fuels on 1,171 acres by underburning, crushing, machine piling, pruning/chipping, or handpile burning, and constructing and reconstructing roads.Item Open Access 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.
