  2. Dead/Dying Douglas-fir • Harvest up to 95% of dead/dying trees <35” DBH • Harvest green Douglas-fir with extensive budworm damage and/or evidence of successful beetle attack • Leave all Douglas-fir snags >36” unless they present a safety hazard Granite Creek area

  3. Green Douglas-fir and Mixed Conifer • Thin Douglas-fir from below to average residual basal area of 80 ft2/ac • Basal area would vary from 20 – 120 ft2/ac depending on site conditions California Creek area Historic Douglas-fir savannah with second growth understory

  4. Green Douglas-fir and Mixed Conifer • Harvest all live lodgepole pine infested with bark beetles and 90% of dead/dying lodgepole • Harvest subalpine fir • Leave Engelmann spruce if in small patches (<1 acre) or in streamside management zone • If in patches >1 acre, patch cut up to ½ acre Mixed conifer stand in Fletcher Creek area

  5. Green Douglas-fir and Mixed Conifer California Creek area

  6. Pre- and Post-treatment Basal Area(Barton Gulch timber sale) • Pre-treatment • Basal area ~ 200 ft2/ac • Silvicultural prescription • Thin from below • Post-treatment • Basal area averaging 80 ft2/ac • Varies from 40 to 140 ft2/ac depending on site conditions Barton Gulch timber sale

  7. Average 80 ft2/ac Residual Basal Area Barton Gulch timber sale

  8. Previously managed Douglas-fir(primarily in the Meadow Creek area) • Harvest recent dead/dying trees as needed • Leave all existing snags unless they present a safety hazard Previously harvested stand in Meadow Creek area
