Existing Condition: Stand is mature old-growth structure beyond CMAI.
Prescriptions: Even-aged system using the clearcut (CC) method. Uneven-aged system (UA) by single-tree selection (STS) method. STS removes up to 33 percent of existing live basal area.
Justification for clearcutting: High level of wind hazard. Moderate levels of wood decay, dwarf mistletoe and yellow-cedar decline.

Planned landings on new temporary road the takes off existing NFS road 6277 will facilitate harvest of settings 1, 4 and 6. Planned landings along existing NFS road 6270 will facilitate harvest of settings 3, 5 and 7.

INVASIVE SPECIES: Eradicate all newly introduced invasive plants prior to closing out temporary roads.
SOILS: Minor exclusions were made due to slope stability concern. Require full suspension on steep slopes in settings 811-1 and 811-3.
WETLANDS: Temporary road is located in wetlands - minimize foot print to the extent possible, follow BMP 12.5.

INVASIVE SPECIES: Eradicate all newly introduced invasive plants prior to closing out temporary roads.
SOILS: Broken topography not well represented by contour lines. Layout to ensure soil quality standards can be achieved.
WETLANDS: Temporary road is located in wetlands - minimize foot print to the extent possible; expect shovel yarding and landing locations to be located in wetlands - minimize disturbance to the extent feasible, follow BMP 12.5.

PLANTS: SENSITIVE & RARE: A rare plant population (Lycopodiella inundata, Site ID 100522P000098) is located in muskeg between the northeastern boundary of setting 814-10 and the northwestern boundary of setting 814-8. Avoid population during project activities. Employ directional falling and yarding of trees in harvest unit away from population. A Forest Service botanist will flag the population prior to initiation of project activities and will monitor implementation of protection measures during and/or after harvest.
SOILS: Broken topography with areas having slope steeper than 72 percent; partial harvest prescription and helicopter logging will mitigate soil impacts.
