It is bisected by Soda Springs Road and surrounds the community of Serene Lakes. The study area is within portions of Sections 21, 23 through 28, 34, and 35, Township 17N, Range 14E and Section 3, Township 16N, Range 14E of the Soda Springs and Norden 7.5 minute USGS quadrangles (Figure 1). Approximate latitude and longitude of the center of the study area are 39º 18’ 36”north and 120º 23’ 02” west. Figure 2 is an aerial photograph showing the Royal Gorge Area. Study Objectives This study represents a preliminary analysis of the literature and existing site conditions on the Royal Gorge study area. The purpose of the work is to provide a broad analysis of biological resources on the study area for planning purposes. The objectives of this study are to: • Identify and describe the biological communities present on the project site, • Record plant and animal species observed on the project site, and • Evaluate and identify sensitive resources and special-status plant and animal species that could occur in the project area. METHODS Literature Review A variety of resources were used in this assessment. Aerial photographs and boundary and topographic mapping were supplied from Andregg Geomatics. Soil information was obtained from the Soil Survey, Tahoe National Forest Area, California (USDA, NRCS 2002, electronic edition), and geological information was obtained from the Geologic Map of California, Chico Sheet (California Department of Conservation 1962). The following publications were reviewed to provide information on life history, habitat requirements, distribution, and conservation status of regionally occurring plant and animal species: Jepson Manual; Higher Plants of California (Hickman 1993), California Vegetation (Holland and Keil 1995), A Field Guide to Western Reptiles and Amphibians (Stebbins 1985), A Field Guide to the Birds of North America (National Geographic Society 1999), Mammals of the Pacific States (Ingles 1965), and California’s Wildlife: Volumes I (Amphibians and Reptiles), II (Birds), and III (Mammals) (Zeiner et al., 1988, 1990). In addition to these references, the following environmental documents were reviewed: Nevada County Natural Resources Report (Nevada Royal Gorge Biological Resources Assessment 1 Project Site Not Part of Study Area Serene Lakes Project Site 0 1000 2000 Approximate scale in feet Figure 1 Area: Royal Gorge Holdings: ± 2,896 acres N W E SITE & VICINITY S Royal Gorge Base map: Norden & Soda Springs, CA, USGS 7.5 minute topographic quadrangles Placer & Nevada Counties, California Project Site Not Part of Study Area Figure 2 ± NOTES: Aerial photo provided by: Andregg Aerial photo date: 2005 AERIAL MAP 0 750 1,500 3,000 Royal Gorge Scale in Feet Placer & Nevada Counties, California County 2003), Draft Initial Study/Environmental Assessment for the Placer 80 Roadway Rehabilitation Project (Caltrans 2004), Royal Gorge Lodge and Homesites at Summit Valley Draft EIR (Nevada County 2004), Blue Canyon Deer Herd Management Plan (Fowler and Wagner 1982), as well as species lists from the Sagehen Creek Field Station - Biological Inventories. North Fork staff’s review did not identify local ordinances or habitat conservation plans, with the exception of applicable Nevada and Placer County policies. Furthermore, North Fork staff is not aware of any such ordinances or plans that are not embodied in County policies.” Special Status Species Reports North Fork Associates queried the California Natural Diversity Database (CNDDB) for a list of special status plant and animal species known to occur in the region. The following USGS quadrangles were included in the query: English Mountain, Webber Peak, Indian Lake, Norden, Granite Chief, Royal Gorge, Duncan Peak, Cisco Grove, Truckee, and Tahoe City. In addition, NFA reviewed lists of special status species in Nevada and Placer counties maintained by the U.S. Fish and Wildlife Service, Tahoe National Forest, and the California Native Plant Society. Appendix A is a table of special status plant species resulting from these information sources. Appendix B is a similar table of special status wildlife known to occur in the region. For the purposes of this report, special status species are those that fall into one or more of the following categories: • listed as endangered or threatened under the federal Endangered Species Act (or formally proposed for listing), • listed as endangered or threatened under the California Endangered Species

DATE: November 2009 APPROVED BY: DATE: _____________ Name, Forest Botanist, Lake Tahoe Basin Management Unit SUMMARY OF EFFECTS DETERMINATION AND MANAGEMENT RECOMMENDATIONS AND/OR REQUIREMENTS One population of a special-status bryophyte, three-ranked hump-moss (Meesia triquetra), was observed in the survey area during surveys on June 30, 2008 and August 28, 2008. The proposed action will not affect the moss because the population is located outside the project area where no action is planned. The following species of invasive or noxious weeds were identified during surveys of the Project area: cheatgrass (Bromus tectorum); bullthistle (Cirsium vulgare); Klamathweed (Hypericum perforatum); oxe-eye daisy (Leucanthemum vulgare); and common mullein (Verbascum Thapsus). The threat posed by these weed populations would not increase if the proposed action is implemented. An inventory and assessment of invasive and noxious weeds in the survey area is presented in the Noxious Weed Risk Assessment for the Upper Truckee River Sunset Stables Restoration Project (ENTRIX 2009). Based on the description of the proposed action and the evaluation contained herein, we have determined the following: There would be no significant effect to plant species listed as threatened, endangered, proposed for listing, or candidates under the Endangered Species Act of 1973, as amended (ESA), administered by the U.S.

The trail would be constructed, managed, and maintained by the Bear-Yuba Land Trust, a private non-profit organization. The project would expand an existing small, primitive trail and construct a new segment of trail on Sugarloaf Mountain, just north of Nevada City. The trail begins near the intersection of State Route 49 and North Bloomfield Road and terminates on Sugarloaf Mountain. The proposed trail includes a quarter-mile segment on an easement through private land. The project drawings are provided in Appendix A. Trail tread width will vary from 36 to 48 inches, depending on location and physical constraints, and constructed using a mini excavator, chainsaws, and a variety of hand tools.

  • Washington Flora Checklist a Checklist of the Vascular Plants of Washington State Hosted by the University of Washington Herbarium
    Washington Flora Checklist A checklist of the Vascular Plants of Washington State Hosted by the University of Washington Herbarium The Washington Flora Checklist aims to be a complete list of the native and naturalized vascular plants of Washington State, with current classifications, nomenclature and synonymy. The checklist currently contains 3,929 terminal taxa (species, subspecies, and varieties). Taxa included in the checklist: * Native taxa whether extant, extirpated, or extinct. * Exotic taxa that are naturalized, escaped from cultivation, or persisting wild. * Waifs (e.g., ballast plants, escaped crop plants) and other scarcely collected exotics. * Interspecific hybrids that are frequent or self-maintaining. * Some unnamed taxa in the process of being described. Family classifications follow APG IV for angiosperms, PPG I (J. Syst. Evol. 54:563?603. 2016.) for pteridophytes, and Christenhusz et al. (Phytotaxa 19:55?70. 2011.) for gymnosperms, with a few exceptions. Nomenclature and synonymy at the rank of genus and below follows the 2nd Edition of the Flora of the Pacific Northwest except where superceded by new information. Accepted names are indicated with blue font; synonyms with black font. Native species and infraspecies are marked with boldface font. Please note: This is a working checklist, continuously updated. Use it at your discretion. Created from the Washington Flora Checklist Database on September 17th, 2018 at 9:47pm PST.
