Mount Pinos Forest Health Project Proposal Mount Pinos Forest Health Project Los Padres National Forest Mount Pinos Forest Health Project Proposal Introduction The Los Padres National Forest proposes to implement a Forest Health project in the Mount Pinos area on the Mount Pinos Ranger District. The project area encompasses approximately 1,682 acres on the eastside shoulder of Mount Pinos between the Cuddy and Lockwood Valleys. The project area is located in both Ventura and Kern Counties, California (figure 1). The Mount Pinos Forest Health Project area lies within an Insect and Disease Treatment Designation Area1 where declining forest health conditions put the area at risk for substantial tree mortality. The purpose of this project is to reduce existing stand densities and alter stand structure and species composition to create landscapes more resilient to impacts of drought, insects, and disease.2 Figure 1. Mount Pinos Forest Health Project vicinity map This project would improve forest health by reducing existing stand densities and the risk of tree mortality through the removal or on-site treatment of small-diameter, less than 24-inch and dead trees from overstocked stands. Treatments would consist of either mechanical and/or manual thinning methods. 1 https://www.fs.usda.gov/managing-land/farm-bill/area-designations 2References are available at: www.fs.usda.gov/main/lpnf/landmanagement/planning or are on file at the Mt. Pinos Ranger District in Frazier Park, California. 1 Mount Pinos Forest Health Project Los Padres National Forest Prescribed fire and pile burning would be used as needed. The proposed treatments would also benefit fire and fuels management by reducing surface, ladder, and crown fuels. High tree density levels, overlapping tree crowns, and a dense understory contribute to resource competition, leaving trees at risk from drought, insects and disease, and wildfire. Treating these areas will reduce competition, improve the health of the remaining trees, and increase the average stand diameter. The project, located in proximity to Cuddy Valley, extends to the upper slopes of Mount Pinos. The project area is approximately 1.5 miles southwest of the community of Pinon Pine Estates and approximately 2 miles southeast of the community of Pine Mountain Club. The legal description for the project area is T8N, R21W, Sections 3, 4, 5, 8, 9 and T9N, R21W, Sections 26, 33, 34, 35, 36 San Bernardino Meridian; Kern and Ventura County, California (Figure 2). Figure 2. Mount Pinos Forest Health Project area The project area lies within a designated Insect and Disease Treatment Area where declining forest health conditions put the area at risk for substantial tree mortality over the next 15 years. In the 2014 Farm Bill, Congress authorized the United States Department of Agriculture (USDA 2003, amended 2018) Forest Service to prioritize work in these designated areas, and to expeditiously plan and implement those projects. The Farm Bill also specified that certain projects within insect and disease infested areas would be categorically excluded from the requirements of the National Environmental Policy Act (NEPA). The law specified that these categorical exclusion projects are exempt from the pre-decisional administrative review objections process, and to be considered the project must fall within the wildland-urban interface; or Condition Classes 2 or 3 in Fire Regime Groups I, II, or III, outside the wildland urban interface. This 2 Mount Pinos Forest Health Project Los Padres National Forest project falls within the areas to be considered as defined by the Healthy Forest Restoration Act (USDA 2003, as amended 2018). The Healthy Forest Restoration Act authority (USDA 2003, as amended 2018) would be used for this project. The purposes of the act relevant to this project include actions to: • reduce risk or extent of, or increase the resilience to, insect or disease infestation; • enhance efforts to protect watersheds and address threats to forest and rangeland health, including catastrophic wildfire, across the landscape; • reduce wildfire risk to communities, municipal water supplies, and other at-risk Federal land through a collaborative process of planning, prioritizing, and implementing hazardous fuel reduction projects; • protect California spotted owl habitat (Forest Service Sensitive Species) to the north of the treated area from the effects of catastrophic wildfire. Figure 3 shows the vegetation within a 1,500-foot buffer around the project area in relation to wildlife habitat (California Spotted Owl), created by a wildlife suitability model (Zeiner et al. 1998 and 1990). Figure 3. Wildlife suitability habitat map for the Mount Pinos Project 3 Mount Pinos Forest Health Project Los Padres National Forest Existing Condition (Affected Environment) and Desired Conditions Existing Conditions Vegetation A century of fire suppression, logging and grazing has influenced the present condition of vegetation in the Los Padres National Forest (Nigro and Molinari, 2019). As a result, many conifer forests now have tree densities that are much higher than pre-settlement levels (LMP Part 1 pages, 13, 21, 23; Taylor, 2007; Goforth and Minnich 2008). Additionally, species composition is trending away from shade-intolerant species, such as Jeffrey and ponderosa pine toward shade-tolerant species, such as white fir and incense cedar when compared to historic abundances. (USDA 2005, LMP Part 1). Densification has been occurring in southern California (Minnich et al, 1995; Taylor, 2007; Goforth and Minnich 2008) since the suppression of fire began at least 100 years ago. Adult tree density and basal area in the San Bernardino Mountains were nearly double that of the Sierra San Pedro Martir3. Because of this densification, exacerbated by drought conditions, there were three times as many standing dead Jeffrey pine and white fir in southern California as in Baja California. As a result of previous management actions, most trees in southern California established in the last 100 years; the maximum age of Jeffrey pine was around 285 years in southern California, whereas the oldest Jeffrey pine tree in the Sierra San Pedro was 448 years old (Gucker, FEIS report, 2007). Figure 4 (LMP Part 1 page 24) is an example of a representation of shade-intolerant Jeffrey and ponderosa pines. It illustrates the past versus the present conditions throughout its range. The current conditions in the project area are consistent with this trend of a higher percentage of the shade-tolerant white fir in present- day forests. Note: JP and PP = Jeffrey pine and ponderosa pine; WF = white fir; BO = black oak; SP = sugar pine, and IC = incense cedar Figure 4. Historic and current percentages of tree species in western mixed conifer forests 3 The San Pedro Martir area of northern Baja, Mexico, has received minimal management activities unlike southern California and is used as a reference condition. 4 Mount Pinos Forest Health Project Los Padres National Forest Site reconnaissance of the project area showed a patchy, mosaic stand structure with some of the project area already similar to historic conditions with respect to desired stand density and structure. During project implementation, these areas would receive minimal or no treatment to the existing overstory trees (Figure 5). Figure 5. Example of area already at desired structure needing little or no overstory treatment However, approximately thirty eight percent4 of the project area is in excess of what was present historically (Minnich et al. 1995) due to densification (Figure 6). Overcrowding has accelerated and aggravated drought- caused mortality, making conifer forests susceptible to widespread insect and disease outbreaks that, combined with excessive fuel loading, has the potential for more large-scale mortality as a result of insects and disease, drought, and stand-replacing wildland fires. 4 Derived from stand exam data collected in the project area. 5 Mount Pinos Forest Health Project Los Padres National Forest Figure 6. Example of area needing treatment due to densification Stand exams taken in the project area coupled with walk-throughs by certified silviculturists and other Forest professionals5 confirm that existing stand density and structure put the area at risk from insects and disease as well as from wildfire. Historically, mixed conifer stands in southern California had approximately 93 trees greater than 4 inches DBH per acre (Minnich et al. 1995). Stand exam data show the project area averages 145 trees per acre greater than 4 inches DBH in mixed conifer stands, exceeding the historic level. Figure 7 is a good representation of forest densification at the Mt. Pinos snow play area that is within the project area. High stocking levels, overlapping tree crowns, and a dense understory contribute to competition that leaves trees and especially large trees more susceptible to bark beetle attacks (Fettig et al, 2012; Bennet et al, 2015; Bradford and Bell, 2017). The existing understory, close tree crowns, understory ladder and downed fuels and continued periods of drought also place the area at risk for wildfire. The existing conditions of the timbered stands do not meet the goals and desired conditions of the Los Padres National Forest Plan. Specifically, the existing conditions do not meet Forest Plan Goal 1.2: Restoration of Forest Health, Goal 1.1: Community Protection, with Forest Plan desired conditions for FH 2: Restoration of Forest Health and FH 4: Insect and Disease Management, and finally, National Strategic Plan Goal 1 – Reduce the risk from catastrophic wildland fire. 5 Mount Pinos Community Wildfire Protection Plan, National Insect and Disease Forest Risk Assessment, Strategic Fuelbreak Assessment, and the 2014 Farm Bill. 6 Mount Pinos Forest Health Project Los Padres National Forest Figure 7. Mount Pinos snow play area showing dramatic increase in density of trees, 2020 and 1963 7 Mount Pinos Forest Health Project Los Padres National Forest The project area has approximately 1,543 acres of Jeffrey pine, mixed conifer, and pinyon-juniper dominated stands. These stands are experiencing elevated levels of bark beetle activity and associated increasing tree mortality, which has been exacerbated by the ongoing drought.

These four mountains supportislands of coniferousforest separated by otherhabitats at lower elevations. Little information on the birds of the first three has been publishedpreviously. From 1981 to 1993, I, withthe helpof a numberof observers,censused the summer residentbirds of these four mountains,paying particular attentionto the speciesrestricted to highelevations. By comparingthese avifaunaswith each other, as well as with those of the San Gabriel,San Bernardino,and San Jacinto mountains, and the southernSierra Nevada, I hopeto addto currentknowledge of thestatus and distribution of montane birds in southern California. VEGETATIO51AND GEOGRAPHY The patternof vegetationin the surveyareas is typicalof thatfound on manysouthern California mountains. Generally, the south- and west-facing slopesof the mountainsare coveredwith chaparralor pinyon-juniper woodlandalmost to the summits.On the north-facingslopes, however, coolertemperatures and more mesic conditions support coniferous forest, which often reaches far down the mountainsides. Because the climate is arid, few creeksor streamsflow at high elevations,and most water is availablein the form of seepsor smallsprings. BothFigueroa (4528 feet, 1380 m) andBig Pine (6828 feet,2081 m) mountainsare locatedin the San RafaelRange, the southernmostof the CoastRanges (Figure 1, Norrisand Webb 1990).

While deer densities are low in the Southern Desert bioregion, some of the largest bucks in the state are taken each year in these arid environments. Photo by Mark Hoshovsky H. Southern Desert 1. Deer Habitats and Ecology The Mojave and Sonoran deserts of California support some of our driest and hottest habitats in the state. It comes as no surprise, then, that these areas support some of our lowest deer densities. The deer that inhabit our southern deserts are also the least understood ecologically in California. These animals, while not migratory like those in the Sierra Nevada, do move long distances in response to changes in the availability of water and forage. Summer rains in the desert cause the germination of annual grasses and forbs, and deer will move to take advantage of this forage. Desert washes and the vegetation in them are especially important for providing cover and food, and free-standing water in the summer seems to be essential for maintaining burro mule deer.

Niemi,1 Jamie T. Buscher,2 James A. Spotila,3 Martha A. House,4 and Shari A. Kelley 5 Received 21 May 2013; revised 21 October 2013; accepted 28 October 2013; published 20 December 2013. [1] The San Emigdio Mountains are an example of an archetypical, transpressional structural system, bounded to the south by the San Andreas strike-slip fault, and to the north by the active Wheeler Ridge thrust. Apatite (U-Th)/He and apatite and zircon fission track ages were obtained along transects across the range and from wells in and to the north of the range. Apatite (U-Th)/He ages are 4–6 Ma adjacent to the San Andreas fault, and both (U-Th)/He and fission track ages grow older with distance to the north from the San Andreas. The young ages north of the San Andreas fault contrast with early Miocene (U-Th)/He ages from Mount Pinos on the south side of the fault. Restoration of sample paleodepths in the San Emigdio Mountains using a regional unconformity at the base of the Eocene Tejon Formation indicates that the San Emigdio Mountains represent a crustal fragment that has been exhumed more than 5 km along the San Andreas fault since late Miocene time. Marked differences in the timing and rate of exhumation between the northern and southern sides of the San Andreas fault are difficult to reconcile with existing structural models of the western Transverse Ranges as a thin-skinned thrust system.

    75. Sawmill Mountain (Parikh 1993b) Location The Sawmill Mountain recommended Research Natural Area is on Los Padres National Forest in N. Ventura and S. Kern counties. It lies immediately W. of Mount Pinos, SE. of Cerro Noroeste (Mount Abel), just W. of San Emigdio Mesa, and occupies parts of sects. 25 and 36 T9N, R22W; sects. 30 and 31 T9N, R21W; sects. 1, 2, 11, 12, 13, and 14 T8N, R22W; and sects. 7 and 17 T8N, R21W MDBM (38°48'N., 119°10'W.), USGS Sawmill Mountain quad (fig. 151). Ecological subsection – Northern Transverse Ranges (M262Bb). Target Element Jeffrey Pine (Pinus jeffreyi) Forest Distinctive Features The flora here is mainly derived from the Sierran forest of the West American element of the Arcto-Tertiary geoflora. The pine belt in S. California is similar to the S. Sierra Nevada: many of the high-elevation, montane species with disjunct distributions have affinities with the Sierran flora. Many other species present here are transitional between drier, interior desert flora and montane flora from wetter, cooler regions. Figure 151— Rare Plants: Monardella linoides ssp. oblonga is on CNPS List 1B; Delphinium parishii Sawmill Mountain ssp. purpureum (D. parryii ssp. purpureum in Hickman [1993]), Frasera neglecta rRNA (Swertia n. in Hickman [1993]), and Lupinus elatus are all on CNPS List 4. Rare Fauna: The region is a part of the breeding habitat of the Federally- and State-listed endangered species California condor (Gymnogyps californianus). Physical Characteristics The area encompasses about 3800 acres (1539 ha). Elevations range from 6250 feet to 8750 feet (1905-2667 m) at the summit of Sawmill Mountain.

The species also occurs in the foothills of the Sierra Nevada from El Dorado County to Madera County and on South Farallon, Santa Catalina, Los Coronados, and Ano Nuevo islands off the coast of California (Petranka 1998, Stebbins 1951, Stebbins 1985). Arboreal salamander occurs from sea level to an elevation of about 5,000 feet (1,520 meters) (Stebbins 1985). Distribution in the Planning Area Arboreal salamander reportedly occurs in the foothills and lower elevations of every mountain range on National Forest System lands, although it is seldom seen (Stephenson and Calcarone 1999). There are records of occurrence for this species on the Los Padres National Forest near upper San Juan Creek and on the Cleveland National Forest near Soldier Creek (USDA Forest Service file information), San Gabriel foothills east to Day Canyon, and in the San Jacinto Mountains (Goodward pers. comm.). Systematics There are four species in the genus Aneides in the western United States, three of which occur in California (Stebbins 1985). Of these three, only arboreal salamander ranges into southern California. Most of the Aneides salamanders climb (Stebbins 1985). Arboreal salamander consists of two chromosomally differentiated groups that intergrade in south and east-central Mendocino County, about 56 miles (90 kilometers) north of the San Francisco Bay region (Sessions and Kezer 1987).

It is easy to believe that the fluctuations in type are due to the subspecies being still in a formative process. But it is not possible to imagine that cotlesi and bryanti could maintain their separate status in the same area. Sala Diego, California, June 28, 1933. DESCRTPTTON OF A NEW GROUSE FROM SOUTHERN CALJFORNTA By DONALD R. DICKEY and A. J. VAN ROSSEM ROUSE have long been known to occur on Mount Pinos,’ in Kern and Ventura counties, California, but only recently have specimens become G available for study. Comparison of the series secured during the last few years indicates a geographic variation of Dendragapus obscurus in the southwestern part of its range that is deemed worthy of subspecific recogni- tion. The form may be known as follows: Dendragapus ’ ObSCUIWS howardi, new subspecies Mount Pinos Grouse Type.-Male adult; no. K 238, collection .of Donald R.

Diagltosis.-Nearest to Dendragapus obscurus sierrae, but differing from that form in paler dorsal coloration, and in coarser and more conspicuous ver- miculation and barring. Underparts darker, a brownish suffusion replacing the clearer gray of sierrae. The white median shafting and terminal pattern of the feathers of flanks and sides reduced in area and entirely lacking on anterior part of body, whereas in sierrae traces of this pattern extend for- ward to the shoulders.
