This report presents the results of 5 separate special status plant surveys conducted on approximately 9.85 acres to be developed as Fountaingrove Lodge (Study Area) in Santa Rosa, Sonoma County, California (Figure 1). The purpose of this study is to identify the location and presence of potentially occurring sensitive plant species. Focused special status plant surveys were conducted on October 5 and 14, 2005, June 16, 2006 and February 16, April 9, 2007 by WRA botanists. These surveys coincided with peak blooming periods of all potentially occurring special status species. These surveys did not locate any special status plant species.

1.1 Study Area Description

The Study Area is approximately 9.85 acres and is located in the Santa Rosa USGS 7.5 minute quadrangle, north of Fountaingrove Parkway (also known as Fountain Grove Parkway), northeast of Santa Rosa in central Sonoma County, California (Figure 1). It is bounded by the Fountaingrove Golf Course to the east, Leaf Ranch and a City Park Site to the west, and residential housing to the north and south. The site elevation is approximately 450 feet and the soils are predominantly volcanic in nature. Volcanic outcrops and talus slopes cover a majority of the site. The majority of the Study Area was historically used as rural residential. Land use for the Study Area is currently managed as an undeveloped portion of the golf course. No portions of the Study Area are located within the 100-year floodplain (www.fema.gov).

The Study Area is dominated by oak woodlands with scattered coyote brush (Baccharis pilularis). A stream bisects the southern corner of the Study Area. Man-made stormwater ditches run along the western edge the Study Area, eventually entering culverts running beneath Thomas Lake Harris Drive.

1.1.1 Vegetation

Dominant vegetation in the Study Area was classified according to Holland (1986) in the Biological Resources Assessment Report for Fountaingrove Lodge prepared by WRA (2007) and can be characterized as oak woodland and ruderal annual grassland with scattered coyote brush. In addition, an area of riparian vegetation occurs along the banks of a stream located in the southern portion of the Study Area. The observed plant communities are discussed in detail below and shown in Figure 2.

Oak Woodland

The majority of the Study Area consists of historically disturbed oak woodlands with scattered stands of coyote brush. The overstory is comprised of three oak species, coast live oak (Quercus agrifolia), California black oak (Quercus kelloggii) and blue oak (Quercus douglasii), as well as other tree species such as California bay (Umbellularia californica), Pacific madrone (Arbutus menziesii) and European olive (Olea europaea). The understory consists of poison oak (Toxicodendron diversilobum), snowberry, (Symphoricarpos sp.) and grasses such as California canary grass (Phalaris californica), foxtail barley (Hordeum murinum), rattlesnake grass (), and hedgehog dogtail (Cynosurus echinatus).

An area of riparian vegetation was observed occurring along a stream bisecting the southern corner of the Study Area. Riparian vegetation included scattered cattail (Typha latifolia), rush (Juncus sp.), and knotweed (Polygonum sp.) individuals growing in the stream bed, as well as a few small ash trees (Fraxinus latifolia) on the upper banks.

Ruderal Annual Grassland

Ruderal annual grassland with scattered shrubs occurred between oak woodland stands (Figure 2). Commonly observed species included weedy forbs such as bristly ox-tongue (Picris echioides) and fennel (Foeniculum vulgare), and annual grasses, such as slender wild oat (Avena barbata), false brome (Brachypodium distachyon), rattlesnake grass (Briza maxima), Harding grass (), soft chess (Bromus hordeaceus), and Italian ryegrass (Lolium multiflorum).

1.1.2 Soils

The Sonoma County Soil Survey (USDA 1972) indicates that the Study Area has five native soil types: Goulding cobbly clay loam, 15 to 30 percent slopes; Raynor clay, 9 to 15 percent slopes; Felta very gravelly loam, 15 to 30 percent slopes; Felta very gravelly loam 30 to 50 percent slopes; and Spreckels loam, 9 to 15 percent slopes. These soil types are described in detail below and their extents and locations within the Study Area are shown on Figure 3.

Goulding cobbly clay loam, 15 to 30 percent slopes. This Goulding series consists of well- drained clay loams, underlain by metamorphosed basic igneous and weathered andesitic basalt of old volcanic formations at a depth of 12 to 24 inches. This soil series occurs on mountainous uplands. In a typical profile the surface layer is brown and dark-brown, clay loam about 11 inches thick. The surface layer of this soil contains as much as 25 percent cobblestones and stones and ranges in depth from 16 to 20 inches. The subsoil is dark-brown, very gravelly clay loam about 11 inches thick. Fractured basalt occurs at a depth of about 22 inches. Included in this map unit are small areas of Boomer loam, Spreckels loam, and Toomes loam. Runoff is medium to rapid, and the hazard of erosion is moderate to high. This soil is mainly used for range purposes. In the Study Area, this soil is found throughout the center of the site.

Raynor clay, 9 to 15 percent slopes. The Raynor series consists of well-drained clays underlain by volcanic and andesitic rocks at a depth of 20 to 60 inches. These soils are on rolling hills. In a typical profile the surface layer is black and olive-gray, slightly acid to moderately alkaline clay about 47 inches thick. At a depth of about 47 inches it is pale-olive, very cobbly and stony clay. Basaltic cobblestones and stones are present at a depth of 56 inches. On steeper slopes, this soil is typically only 20 to 40 inches deep. Included in this map unit are small areas of Cotati fine sandy loam, Diablo clay, and Goulding cobbly clay loam. Raynor clay is primarily located along the northern edge of the Study Area.

Felta very gravelly loam, 15 to 30 percent slopes. The Felta series consists of well-drained very gravelly loams that have a very gravelly clay loam subsoil. These soils formed from material from

In a typical profile the surface layer is grayish-brown, very gravelly loam about 5 inches thick. At a depth of about 24 inches this soil is a mixed volcanic tuff, river sediment, metamorphosed basic rock, and grayish- brown, strongly acid, sandy clay loam. This soil type is 50 to 60 percent gravel by volume throughout the profile. Included in this map unit area small areas of Guienoc gravelly silt loam, Spreckels loam, and Toomes rocky loam. Felta very gravelly loam, 15 to 30 percent slopes is located along the northern edge of the Study Area.

Felta very gravelly loam, 30 to 50 percent slopes. This soil type is similar to Felta very gravelly loam, 15 to 30 percent slopes, but has more rapid runoff and higher erosion hazard. The depth to sub-stratum is 14 to 18 inches, and there is less clay in the subsoil on these steeper slopes. Felta very gravelly loam, 30 to 50 percent slopes is located in a small region along the southwestern edge of the Study Area.

Spreckels loam, 9-15 percent slopes. The Spreckels series consists of well-drained loams that have a clay subsoil. They are underlain by volcanic tuffs mixed with uplifted river sediment and weathered, basic igneous rock. In a typical profile the surface layer is grayish brown loam and light gray clay loam. This layer is about 18 inches thick. The subsoil is brown and pale brown clay about 19 inches thick. The substratum is about 37 inches deep and consists of clay. This soi ltype occurs on uplands with short and abrupt slopes. In the Study Area, Spreckels loam, 9-15 percent slopes occurs through the center of the site.

2.0 METHODS

2.1 Background Data

Rare are defined here to include: (1) all plants that are federal- or state-listed as rare, threatened or endangered, (2) all federal and state candidates for listing, (3) all plants included in Lists 1 through 4 of the CNPS Inventory (Skinner and Pavlik 1994), and (4) plants that qualify under the definition of "rare" in the California Environmental Quality Act, section 15380.

Background information searches were conducted prior to all site visits to identify potential rare plant species or sensitive plant communities recognized by the California Department of Fish and Game (CDFG) that may occur in the Study Area vicinity. A table of these species, and their protection status, habitat requirements, and likelihood to occur in the Study Area is provided in Appendix B. Sources for this search included the California Department of Fish and Game (CDFG) Natural Diversity Database (CDFG 2005, 2006 and 2007) records, the California Native Plant Society (CNPS) Electronic Inventory of Rare and Endangered Vascular Plants of California (CNPS 2005, 2006 and 2007), and the U.S. Fish and Wildlife Service species lists for the USGS Santa Rosa, Sebastopol, Mark West Springs, Calistoga, Kenwood, Glen Ellen, Cotati, Two Rock, and Healdsburg quadrangles.

2.2 Field Survey

Focused rare plant surveys were conducted on October 5, and October 14, 2005, June 16, 2006, and February 16, April 9, 2007. During these surveys, the entire Study Area was traversed on foot in a meandering transects fashion. These rare plant surveys corresponded to peak blooming periods for observing and accurately identifying all of the 64 rare plant species with potential to

6 occur within the vicinity of the Study Area. The field survey was conducted by botanists (Amy Parravano, Ann Huber, and Julie Rentner) who have experience performing rare plant surveys and identifying the rare plant species that could occur in the area. The surveys followed the protocol for plant surveys described by Nelson (1987). This protocol complies with recommended resource agency guidelines (CNPS 2001, CDFG 2000, USFWS 1996). All plants were identified using The Jepson Manual (Hickman 1993), to the taxonomic level necessary to determine whether or not they were rare. A list of observed plant species is provided in Appendix C.

3.0 RESULTS

3.1 Background Data Search Results

Based upon a review of CNDDB (CDFG 2005, 2006 and 2007), USFWS species lists, and CNPS Electronic Inventory (CNPS 2005, 2006 and 2007) records, it was initially determined that 64 special status plant species were documented to occur in the vicinity of the Study Area (Appendix B). These species were the focus of protocol-level special status plant surveys conducted in 2005, 2006 and 2007.

3.2 Field Survey Results

One hundred two (102) plant species were observed within the Study Area during the rare plant surveys. The surveys coincided with peak blooming periods for all special status plant species with potential to occur in the Study Area. No special status plant species were detected during these surveys.

4.0 CONCLUSIONS

No special status plant species were found on the Study Area during the rare plant surveys conducted during 2005, 2006, and 2007. Site visits coincided with peak blooming periods for all of the 64 potentially occurring special status plant species identified in the literature.
