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.
