Boggs Mountain Demonstration State Forest Draft Management Plan, June 2008 this management plan. These silvicultural methods will also improve the resiliency of the Forest to catastrophic wildfire. Stand replacing wildfires usually release large amounts of carbon into theatmosphere and also greatly diminish the ability of whatever forest cover remains to sequester new carbon for many decades afterwards. Biomass fuels produced on the Forest also provide an opportunity to replace fossil fuels with an alternative energy source that is close to carbon neutral. The Department is exploring the potential for locating a bio-energy plant on or near the Forest. Fish, Wildlife and Plants Due regard will be given to the preservation of wildlife values. BMDSF has two California Wildlife Habitat Relationship (WHR) System habitat types; ponderosa pine and Douglas-fir. Brush or meadows cover approximately 2 percent of the total landbase. The ponderosa pine habitat type is mainly on the south and west slopes and the Douglas-fir habitat type is mainly on the north and east slopes. Hunting, urbanization, and resource extraction are obvious impacts to wildlife on the State Forest. Because of its easy access and its proximity to large urban areas, BMDSF is heavily used for hunting and target shooting. In addition to the hunting pressures, the Forest is bounded by high density subdivisions on its south and west sides, with the Loch Lomond rural residential area located across Big Canyon to the north. The Forest is open to hunting in accordance with State Fish and Game laws and Section 4656 of the PRC. Although the management of BMDSF has little control over hunting and urbanization pressures placed on wildlife and their habitat, it does have a responsibility to consider the maintenance and enhancement of biological diversity when proposing forest management projects. Biological diversity can be defined as the variety and variability of living organisms and the ecological complexes in which they occur. Biological diversity is an important ecosystem characteristic for a variety of ecological, economic, and aesthetic reasons. For snag recruitment, on case by case basis, trees larger than 40 inches DBH (currently 0.2 per acre on average) will be evaluated for retention based on aesthetic, wildlife, and genetic values. The development of BMDSF as true all-aged forest will provide for a more biologically diverse habitat than is found in the current predominantly young forest. The single tree selection, group selection, commercial thinning, and sanitation-salvage harvesting will improve the forest habitat by developing and maintaining a variety of crown levels, stand densities, and small openings in the Forest. Group selection openings will provide habitat for wildlife species that prefer and need edge cover. The openings themselves will provide feeding habitat for rodents and the predators that feed on the rodents. The multilevel forest canopy will provide habitat for the wildlife that lives in the various levels of the forest canopy. The variable crown canopy density will allow varying amounts of light to reach the forest floor which will determine the amount and types of vegetation which may grow on the forest floor and provide cover, food, and shelter for wildlife that utilizes the forest floor. Rare, Threatened or Endangered Species The BMDSF is type C spotted owl habitat (14 CCR 895.1). Spotted owls do not nest within BMDSF at this time, however a single transient owl has been located in the vicinity of Malo Creek on numerous occasions. Periodic owl surveys will be conducted by Forest staff in accordance with the US Fish and Wildlife Service (USFWS) approved protocol as described in “Guidelines for Surveying Proposed Management Activities that may Impact Northern Spotted Owls”. 32
Boggs Mountain Demonstration State Forest Draft Management Plan, June 2008 In order to satisfy the disclosure requirements of the Forest Practice Rules and CEQA, CAL FIRE has sought from USFWS technical assistance to the Northern Spotted Owl Guidelines. The purpose of the Guidelines is to ensure that THPs submitted within the range of the northern spotted owl will not likely result in take of this federally listed species. The management of Boggs Mountain is aimed at creating mixed structure stands. These stands fit the habitat requirements of the northern spotted owl well. The Natural Diversity Data Base indicates that Rincon Ridge ceanothus (Ceanothus confuses) was identified and last seen in 1940, one+ mile northwest of the Forest along what is now State Highway 175. Botanists working on the BMDSF fauna and flora assessment in 1991-92 (Baad, 1992) have identified squaw carpet (Ceanothus prostratus) on the Forest but have not found Rincon Ridge ceanothus. If this species is present on BMDSF, the ground disturbance and openings in the forest canopy created by the timber harvest will improve its habitat by reducing competition and allowing more light to reach the forest floor. Two sensitive plant taxa were identified during the recent (2006) botanical surveys. Konocti manzanita (Arctostaphylos manzanita ssp. Elegans) and Sonoma manzanita (Arctostaphylos canescens ssp. sonomensis ) are listed as CNPS 1B species that could potentially be impacted by timber harvesting operations. Impacts to this species would primarily occur from construction of new skid trails. The established network of skid trails within the state forest shall be used wherever possible, in order to minimize potential impacts. Considering the large population of these two Manzanita species found throughout the state forest, the proposed silvicultural methods, the use of existing landings, skid trails, and roads, and the lack of herbicide use it appears that no significant adverse impact to the population will occur. Watershed and Fisheries BMDSF lies within four Calwater Planning Watersheds: Big Canyon Creek (5512.300105), Upper Kelsey Creek (5512.300103), Anderson Creek (5512.300101), and Hoodoo Creek (5512.300102). Protection of watershed values will be an integral part of the overall management of the Forest and will be directly correlated with silvicultural practices and logging standards pursuant to Section 4651 of the PRC and the Forest Practice Act. Upper Kelsey Creek, Anderson Creek, and Hoodoo Creek planning watersheds have been designated as within the Evolutionary Significant Unit (ESU) for Chinook salmon, Coho salmon, and steelhead trout within the FRAP Calwater mapping system. However, consultations with DFG personnel indicate that Timber Harvest Plans submitted within these watersheds may operate under the standard rules because of downstream barriers to Anadromous species.
