T. Harvey & Associates i Special-status Plant Surveys August 2015 Section 1.0 Introduction This report summarizes the methods and findings of rare plant surveys conducted on the Tenaya Lodge Explorer Cabins Project (Project) site. The results of these surveys supplement the analysis provided by the Project’s Biotic Report (H. T. Harvey & Associates 2014) and are intended to support Project compliance with the California Environmental Quality Act and other applicable regulations. The Project involves constructing a high-end camping facility on approximately 24 acres in the community of Fish Camp, Mariposa County, California. The Project site lies on the western slope of the central Sierra Nevada, approximately 2.8 miles south of the southern entrance to Yosemite National Park and 12.6 miles north of Oakhurst (Figure 1). Its elevation ranges from 4970 to 5050 feet above sea level. The site is bounded to the south by Tenaya Lodge at Yosemite, a resort operated by Delaware North Companies Parks & Resorts; to the west by State Route (SR) 41; and to the north and east by private property. The Sierra National Forest surrounds the community of Fish Camp. Tenaya Lodge Explorer Cabins H. T.

It is bordered by wetlands, including a wet meadow at the south end of the site, Big Rainier Creek, and a 1-acre permanent freshwater pond at the northwestern end of the site. Nine habitat types are present on the site: lower montane coniferous forest, alder/white fir/incense cedar riparian complex, willow shrub riparian/wetland, aspen forested wetland, wet meadow, freshwater pond, perennial stream, intermittent stream, and drainage channel (Figure 2). 1.2 Special-status Plant Species with Potential to Occur Of the 45 special-status plant species identified in the background review, 23 have potential to occur on the Project site (Table 1). Twelve of these species have the potential to occur in the forested areas on the site: Bacigalupi’s yampah (Perideridia bacigalupii), chaparral popcornflower (Plagiobothrys torreyi var. perplexans), Coleman’s rein orchid (Piperia colemanii), Fresno ceanothus (Ceanothus fresnensis), Jepson’s dodder (Cuscuta jepsonii), mountain lady’s slipper (Cypripedium montanum), oak-leaved nemophila (Nemophila parviflora var. quercifolia), oval- leaved viburnum (Viburnum ellipticum), short-bracted bird’s-beak (Cordylanthus rigidus ssp. brevibracteatus), short- leaved hulsea (Hulsea brevifolia), sierra clarkia (Clarkia virgata), and Small’s southern clarkia (Clarkia australis). Ten species may occur in the wet meadow, forested/shrub wetlands, or in and along Big Rainier Creek: Bolander’s bruchia (Bruchia boladeri), Bolander’s clover (Trifolium bolanderi), Bolander’s woodreed (Cinna bolanderi), brook pocket moss (Fissidens aphelotaxifolius), flaming trumpet (Collomia rawsoniana), grey-leaved violet (Viola pinetorum ssp. grisea), mud sedge (Carex limosa), slender stemmed monkeyflower (Mimulus filicaulis), yellow-lip pansy monkeyflower (Mimulus pulchellus), and western waterfan lichen (Peltigera gowardii). Ribbonleaf pondweed (Potamogeton epihydrus) has potential to occur in the pond. Information on the life history and distribution of these plant species is included in the Project’s Biotic Report (H. T. Harvey & Associates 2014), or in Section 4.0 below. Tenaya Lodge Explorer Cabins H. T.
