1 Sequoia Ecological Consulting,Inc. CaIVTP Project-Specific Analysis and Addendum C i6 Augustin Bernal Community Park Fuel Reduction November 2025 • Manual and Herbicide Treatment Activities o Scrub would be retained in a natural mosaic through the removal of invasive species,thinning out dead branches from shrubs, and limbing up large shrubs o Small encroaching trees(under 6 inches DBH) may be removed,and limbs would be removed from larger trees up to 6 feet, as appropriate o Cut vegetation would be lopped and scattered,chipped and broadcast, pile burned,or hauled off- site o Broom plants or other invasive shrubs and noxious weeds would either be uprooted and pulled or cut low to the ground and spot treated with herbicide o Herbicide spot treatment of invasive species and noxious weeds would be hand-applied • Prescribed Herbivory Treatment o Goats, cattle, or other grazing animals would be installed strategically within areas with wildlife- safe fencing or existing barriers o A professional shepherd would coordinate animal movements to prevent excessive grazing and ground disturbance • Biomass Disposal o Biomass from non-invasive, non-noxious plants would be left to naturally decompose (e.g., lop and scatter, chip and broadcast), pile burned, or hauled off-site o Poison oak would be cut and left in place(lop and scatter) o Where chipper access is not practical, cut material would be piled strategically for later burning o Within suitable habitat for Alameda whipsnake, piles left in place for a critical length of time as determined by a professional would be dismantled and reconstructed prior to burning Tree Fuel Type Treatment Activities Tree fuel types would include habitat classified by the CWHR as blue oak woodland and coastal oak woodland.The general approach to tree fuel types would be designed to prevent fire from approaching or departing the fuel break, prevent fire from laddering into the tree canopy, and promote establishment of native trees. Selective thinning would result in a shaded fuel break that retains the tree canopy.This would be achieved through removal of select trees, branches, shrubs, and both living and dead vegetation that could facilitate the upward spread of fire from surface fuels to the forest canopy.The shade of the retained canopy would reduce the potential for rapid re-growth of understory, and the selectively treated areas would provide firefighters an opportunity to access lower-intensity ground fires, should they occur. Within all wooded areas,vegetation removal would be addressed primarily with manual treatment activities to preserve a natural appearance. Other treatment activities used within forest fuel types would include mechanical equipment, herbicides, prescribed herbivory, and prescribed burning. • Manual Treatment Activities o Hand-held tools would remove and thin understory shrubs and brush, as well as dead and dying trees and small (less than 6 inches DBH) non-native, invasive trees o Lower tree limbs would be pruned, and most ground vegetation would be removed to break up the horizontal and vertical continuity of flammable vegetation o Invasive species and noxious weeds would be strategically removed first, followed by fire-prone native species, such as oak, pine, coffee berry(Frangula spp.), sage, etc.
