Range - 3 Meadows (dry or wet) shall not be used for landings, staging areas, or contractor camping. No planting is proposed in site preparation and planting or salvage units that overlap meadows (dry or wet).

Meadows are defined as a non-forested, herbaceous opening, ¼ acre or larger with at least 50 percent herbaceous groundcover and/or riparian shrubs of alder and willow. Openings covered in ferns

(Pteridium spp.), corn lily (Veratrum spp.), marlahan mustard (Isatis tinctoria) or other weedy species are exempt. Openings characterized by greater than 50 percent barren ground are also exempt.

Watershed - 4 Tractors and mechanical harvesters will be excluded from all riparian reserves associated with stream channels, active landslides, inner gorges, and toe zones of dormant landslide deposits. In

Roadside hazard tree units the equipment will be restricted to the road surface. Equipment will be excluded from wetlands or wet meadows (excluding small springs and seeps). To limit slope disturbance, inner gorge terrain (> 65% slope) that

Watershed - 9 In site preparation units (where no salvage will occur) skidding equipment will be restricted to slopes less than 35% on granitic and schist soil types, and up to 45% on all other soil types. Site preparation treatments in Riparian Reserves will be by hand only.

5300019 Soil types with granitic or schist parent material are most susceptible to rutting and displacement of soil organic matter. See

S&G 3-3.

Watershed - 11 Site preparation treatments would be designed to meet soils management direction in the Forest Plan.

Site preparation will be used to reduce fuels where the sum of one-hour, ten-hour, and 100-hour fuels exceeds 7 tons per acre.
