5.3 Biological Resources 5.3 BIOLOGICAL RESOURCES SUMMARY A total of 18 plant communities were identified and characterized during field investigations of the project site. Two of these communities, coast prickly pear succulent scrub and scalebroom scrub, are considered special-status by the California Department of Fish and Game. In addition, 10 special-status plants and 17 special-status wildlife species were identified as potentially occurring on the site. Four of the potentially occurring special-status plant species are currently listed as Threatened or Endangered by state or federal resource agencies: slender horned spineflower (Dodecahema leptoceras), Nevin’s barberry (Berberis nevinii), San Fernando Valley spineflower (Chorizanthe parryi var. fernandina), and Braunton’s milkvetch (Astragalus brauntonii). One potentially occurring special-status animal species is currently listed as federally Threatened: coastal California gnatcatcher (Polioptila californica californica). In addition, a total of 388 oak trees under the jurisdiction of the Section 17.17.090, Oak Tree Preservation, of the City of Santa Clarita Unified Development Code (UDC) occur on the site. Newhall Creek flows through the southern portion of the project site, and several ephemeral drainages flow southward toward Newhall Creek on the slopes of the project site. The principal direct impact of implementation of the proposed project is to convert approximately 43.5 acres of the project site (about 40 percent) from an undeveloped to a developed condition. A total net loss of 43.5 acres of wildlife habitat/natural open space as a result of conversion of undeveloped property to a developed condition will occur. Significant impacts would occur to one special-status plant community, coast prickly pear succulent scrub, and 14 potentially occurring special-status wildlife species. Additionally, the project proposes to remove 79 healthy oak trees, work within the dripline of 75 oak trees, and work within the 5-foot protected zone of 22 oak trees, all of which are significant impacts to oak trees on the project site. With the implementation of the mitigation measures in this section, project-level impacts to biological resources would be less than significant. However, the cumulative loss of coastal sage scrub habitat in the Santa Clarita region is considered significant and unavoidable with implementation of this project. INVESTIGATIVE METHODS Literature Review To identify special-status plant and animal species (those species considered Rare, Threatened, Endangered, or otherwise sensitive by various state and federal resource agencies) that have historically occurred in the vicinity of the project site, the 2006 update of the California Natural Diversity Data Base (CNDDB) as well as the 2006 California Native Plant Society (CNPS) electronic database were reviewed for the USGS 7.5-minute quadrangle on which the project site is located (i.e., Newhall) and the eight Impact Sciences, Inc. 5.3-1 The Master’s College Master Plan Draft EIR 0112.020 July 2008 5.3 Biological Resources surrounding quadrangles (i.e., Green Valley, Mint Canyon, Oat Mountain, San Fernando, Santa Susana, Val Verde, Warm Springs Mountain, and Whitaker Peak). Other information sources reviewed to determine whether suitable habitat for these special-status species may be available on the project site included (1) the California Wildlife Habitat Relationships System life history accounts for special status species (CDFG 2005); (2) NatureServe’s Explorer database of rare and endangered species (2006); (3) California Department of Fish and Game Species Accounts (CDFG 2006); and (4) Sawyer, Keeler-Wolf (1995), Holland (1986), and Munz (1974) for plant community descriptions occurring within the project vicinity. Field Surveys General Biological Survey General biological field surveys were conducted by qualified biologists on the project site in November and December of 2006 to inventory observable wildlife, map and characterize on-site habitats (plant communities), and to evaluate the potential of the site to support special-status species. During the general surveys, direct observations of reptiles, birds, and mammal species were recorded, as well as wildlife signs such as scat and tracks. In addition to species actually detected, expected use of the site by various wildlife species was evaluated through analysis of existing on-site habitats and known habitat preferences of locally occurring wildlife species. Plant communities within the project site were identified, characterized, and mapped with GIS in November of 2006. Vegetation nomenclature used to describe plant communities is primarily based on the CDFG’s List of California Terrestrial Natural Communities (CDFG 2003), but also on Sawyer, Keeler-Wolf (1995), and Holland (1986), where applicable. Common plant names are taken from J.C. Hickman (1993) and P.A. Munz (1974). Focused Plant Survey The potential for special-status plant species to occur on the project site was determined based on the proximity of the site to recorded occurrences listed in the CNDDB and CNPS databases, on-site vegetation and habitat quality, topography, elevation, soils, surrounding land uses, habitat preferences, and geographic ranges of special-status plant species known to occur in the region. On April 24, 2007, Impact Sciences’ biologists conducted focused special-status plant surveys, with an emphasis on identifying whether any of the ten special-status plants with the potential to occur on the site are present on the subject property. The surveys were performed under clear skies, with temperatures ranging from 60 to 75 degrees Fahrenheit. The site was surveyed by walking transects with Impact Sciences, Inc. 5.3-2 The Master’s College Master Plan Draft EIR 0112.020 July 2008 5.3 Biological Resources special attention to those habitats that would support the special-status plants with potential to occur in the project vicinity. Focused Coastal California Gnatcatcher Survey David Crawford of Compliance Biology, Inc., conducted focused surveys for the coastal California gnatcatcher under the authority of his individual Endangered Species Recovery Permit.Based on US Fish and Wildlife Service survey guidelines, six focused surveys were conducted within and adjacent to potentially suitable on-site coastal scrub and buffer habitats with at least a seven-day interval between surveys. Surveys were conducted on April 25, May 1, 8, 15, 22, and 29, 2007. All potential habitat areas were systematically surveyed on foot by walking along random transect routes. The location of transects and survey points along each transect were based on the vegetation and topographic conditions (size, location, and shape of habitat) of the area to be surveyed to ensure complete coverage. A combination of taped vocalizations and “pishing” sounds were used at each calling point. A detailed description of the survey methodology is included in the Results of Focused Coastal California Gnatcatcher Surveys in Appendix 5.3. EXISTING CONDITIONS The project site covers 107.65 acres and is located on the Newhall 7.5-minute USGS quadrangle map in northern Los Angeles County. The site is located within the City of Santa Clarita and is surrounded primarily by single-family homes and ranches. Newhall Avenue/Railroad Avenue lies to the south and west of the project site. Newhall Creek flows through the southern section of the site. Portions of the master plan component of the proposed project lie to the north of Placerita Canyon Road, but most of the master plan and the remaining four project components involve area to the south of this road. The area to be cleared and graded within the proposed grading limit line is located within the larger portion of the project site between Placerita Canyon Road and Newhall Creek. The analysis of potential impacts to biological resources focuses on this proposed impact area within the primary grading footprint, which encompasses 48.9 acres, the proposed storm drain system locations outside of the primary grading footprint and adjacent biological resources. The topography of the impact area ranges from approximately 1,275 feet above mean sea level at Newhall Creek to approximately 1,455 feet at the highest ridgeline. Several ridges stem from the main east-west trending ridgeline and lead south toward Newhall Creek. The topography is highly variable across the impact area with slopes that are steeper than 23 percent. Impact Sciences, Inc. 5.3-3 The Master’s College Master Plan Draft EIR 0112.020 July 2008 5.3 Biological Resources BIOLOGICAL RESOURCES The project site consists primarily of disturbed or ruderal vegetation with remnant patches of coastal sage scrub. There is evidence of past disturbance, including pedestrian/bike trails and charred vegetation that suggests a brush fire occurred in the past few years. The plant and wildlife resources that characterize the project site are discussed below. Those resources considered “common” are discussed first; resources considered special-status by local, state, and/or federal resource agencies are discussed under the Special-Status Biological Resources heading of this document. Plant Communities There are 18 primary plant communities as classified by CDFG’s List of California Terrestrial Natural Communities on site: Big Sagebrush-Rubber Rabbitbrush Scrub, California Sagebrush Scrub, California Buckwheat Scrub, California Sagebrush-California Buckwheat Scrub, California Sagebrush-Deerweed Scrub, Chamise Chaparral, Chamise-California Buckwheat

  • Species Report for the San Fernando Valley Spineflower (Chorizanthe Parryi Var
    Comments on “Species Report for the San Fernando Valley Spineflower (Chorizanthe parryi var. fernandina)” The report presents a misleading representation of the threat of Argentine ant invasion into the areas planned for development by the Newhall Land Company and inadequate information regarding the pollination biology of the SFVS (San Fernando Valley Spineflower). For these reasons, my professional opinion, which is based on over 20 years of experience studying the Argentine ant in the field in California, is that additional research would have to be conducted to assess how the planned developments would impact the Santa Clarita populations of SFVS. In the sections of the report dealing with Argentine ant invasion, several points require clarification. (1) In the interior portions of southern California, the Argentine ant is limited by soil moisture and tends to occur primarily in riparian woodlands and irrigated areas, which can include urban, suburban and agricultural environments. That said, all of the isolated patches of SFVS in Santa Clarita, if exposed to the development illustrated in Figure 4 of the report, would likely be vulnerable to Argentine ant invasion given that they would be surrounded either by urban development or by the Santa Clarita River riparian corridor. Planned urban and suburban developments would affect (and mostly increase) soil moisture levels in unexpected ways by changing impermeable surface cover, storm water run off, flood control measures, irrigation, and landscaping. These changes will increase the risk that isolated SFVS reserves will become invaded by the Argentine ant but will likely do so in ways that are not easy to predict.

Geo­ graphically, the range is transitional to the San Gabriel Mountains, Inner Coast Ranges, Tehachapi Mountains, and Mojave Desert. A total of 1010 vascular plant taxa was recorded from the range, representing 104 families and 400 genera. The ratio of native vs. nonnative elements of the flora is 4:1, similar to that documented in other areas of cismontane southern California. The range is note­ worthy for the diversity of Quercus and oak-dominated vegetation. A total of 32 sensitive plant taxa (rare, threatened or endangered) was recorded from the range.

Except for the effec's of the weather which are given elsewhere in this report, the year was one of steady and sound development. The building program of the previous year had been completed, and early in 1971 landscaping around the annex was finis3ed and the grounds once again were quiet and serene, suitable for study and contemplation by the thousands of persons who visit the garden each year. Among events which undoubtedly will mark this year in the garden's history are two, especially, which should be mentioned. The botanic garden is a member of the American Association of Museums and durinJ; the year we applied for accreditation by that organization. In August we were notified that we had been granted interim approval until an on-site evalu1tion of the institution could be made by the AAM Accredit1tion Visitin~ Commit­ tee. This visit is expected early in 1972. The second item of interest is that the botanic garden for the first time applied for a plant patent to cover a new hybrid which soon will be released to the horticultural trade.

    Monrovia Nursery Specific Plan and Project 4.9 Biological and Agricultural Resources Draft EIR 4.9 BIOLOGICAL AND AGRICULTURAL RESOURCES SCOPE AND METHODOLOGY This section examines the potential for the proposed project to result in significant adverse impacts to agricultural and biological resources. The existence (or lack) of such resources in the project area and immediate surroundings were identified through consultation with appropriate local, state, and federal agencies, including the United States Army Corps of Engineers (Corps), United States. Fish and Wildlife Service (USFWS), California Department of Fish and Game (CDFG), the California Department of Conservation, and the City of Azusa. Biological surveys of the site were conducted by Glenn Lukos Associates, Inc. (GLA) from April to July 2002 to ascertain the nature of biological resources on the site and the potential for impacts (See Appendix G).1 Previous biological surveys were conducted by Michael Brandman Associates (MBA) in 1992 and 1996. MBA reports provided detailed descriptions of the site, including the nursery areas occupied by native habitats.2 3 4 The focus of the 2002 GLA surveys was determined through a review of the MBA reports, which can be viewed in the Rosedale Specific Plan EIR, also used to prepare this Section. Field studies were conducted and focused on a number of primary objectives: (1) confirmation of previous vegetation mapping; (2) focused plant surveys; (3) general wildlife surveys (including considerations of wildlife movement corridors); (4) focused surveys for the coastal California gnatcatcher (Polioptila californica californica); (5); focused surveys for Bell’s sage sparrow (Amphisipiza belli belli) and rufus crowned sparrow (Aimiophila ruficeps) and (6) raptor surveys, and an oak tree survey conducted in accordance with the Los Angeles County Oak Tree Permit requirements set forth in Title 22, Part 16 of the Los Angeles County Code (see Appendix G).

  • Review of Potential Edge Effects on the San
    REVIEW OF POTENTIAL EDGE EFFECTS ON THE SAN FERNANDO VALLEY SPINEFLOWER (Chorizanthe parryi var. fernandina) Prepared for: Ahmanson Land Company and Beveridge & Diamond, LLP Prepared by: Conservation Biology Institute January 2000 INTRODUCTION The recent discovery of the San Fernando Valley spineflower (Chorizanthe parryi var. fernandina) on the Ahmanson Ranch project site in Ventura County, California prompted preliminary investigations into the biology of that taxon. The purpose of these studies is to develop a conservation strategy to protect, maintain, manage, and, possibly, reintroduce the spineflower into appropriate habitat. While the proposed development would remove a portion of the spineflower population, the majority of the known population is proposed to be conserved onsite. Residential development is planned adjacent to the proposed spineflower preserve area. An effective conservation strategy should emphasize preserve design and habitat and species management. Accepted principles of preserve design include maximizing the width of the buffer between development and sensitive resources, minimizing habitat loss, fragmentation, and edge effects, maximizing genetic diversity and connectivity with other habitat patches, maintaining adequate habitat to allow for spatial and temporal population fluctuations, and maintaining a sustainable population size,1 among others. Habitat and species management may be necessary to mitigate impacts from adjacent development and to maintain the functions and values of the population being conserved. This paper assesses potential impacts to the conserved spineflower population from adjacent development based on a review of the scientific literature on edge effects (adverse effects of land uses on adjacent biological resource areas, such as weed invasions or changes in hydrology). A thorough literature search on edge effects has not been conducted for this paper due to time limitations.
