<br /> greater than 40 percent grade with equipment that can reach target vegetation from existing road infrastructure.
<br /> No mechanical treatment would occur on slopes above 50 percent grade. Mowing activity would avoid Alameda
<br /> whipsnake habitat, state or federally jurisdictional waters, and riparian habitat by a no-work buffer, as defined in
<br /> later sections of this document.
<br /> Typical mechanical treatments would require a team with up to 20 workers and equipment such as riding lawn
<br /> mowers, bucket trucks, tow chippers, and track chippers. Typical mechanical treatments would require several
<br /> days to several months to complete, depending on the size of the treatment area, steepness of terrain, and type
<br /> and density of vegetation.
<br /> PD-3.2.3:Manual Treatment
<br /> Ground crews would use hand tools and hand-operated power tools, including chainsaws, hand saws, pole saws,
<br /> McLeods, Pulaskis, weed pullers, weed eaters (e.g., string, plastic blades, or circular blades), brush cutters, and
<br /> loppers to cut, clear, and/or prune trees, herbaceous vegetation, and woody shrubs. Where feasible, treatments
<br /> would prioritize removal of invasive plants and noxious weeds.Within suitable Alameda whipsnake scrub habitat,
<br /> hand-removal would prioritize removal of dead woody vegetation, dead branches, and invasive weeds. Manual
<br /> treatment activities would avoid state or federally jurisdictional waters and riparian habitat by a standard buffer,
<br /> as described in a later section.
<br /> Manual treatments within the project area would require several days to several months to complete, depending
<br /> on the size of the treatment area, steepness of terrain, and type and density of vegetation. Manual treatment
<br /> typically clears 0.3 acres or more per day, per team. Manual treatments typically require 1 or 2 hand crew teams
<br /> with a total of 20 to 40 crew members present on-site.
<br /> PD-3.2.4: Prescribed Herbivory
<br /> Prescribed herbivory involves transporting, releasing, herding, and moving grazing animals, such as cattle, sheep,
<br /> goats, or horses,to designated sites. Herds would be installed strategically within areas with wildlife-safe fencing
<br /> and a professional shepherd, who would coordinate animal movements to prevent excessive grazing and ground
<br /> disturbance. Moving livestock from one grazing ground to another would occur at a frequency based on numerous
<br /> site-specific factors, including slope, density and type of vegetation, stocking rate, type of livestock, and
<br /> precipitation/moisture content of vegetation. Stocking rate would vary based on species of grazer(e.g., a herd of
<br /> cattle would require a larger acreage than a herd of goats of the same size). Site conditions (e.g., relative density
<br /> or quantity of the vegetation to be treated, etc.)would determine herd size and the grazing time to complete the
<br /> job.
<br /> Prescribed herbivory would require temporary wildlife-safe fencing where natural barriers are not present,
<br /> temporary water facilities and other infrastructure(e.g., corrals,fences), and guard animals and/or a shepherd to
<br /> be present on-site. Any areas identified as sensitive to grazing activity would be clearly marked on project maps,
