Fraga ABSTRACT: We present an annotated catalogue of the vascular flora of the upper Santa Ana River watershed, in the southern San Bernardino Mountains, in southern California. The catalogue is based on a floristic study, undertaken from 2008 to 2010. Approximately 65 team days were spent in the field and over 5,000 collections were made over the course of the study. The study area is ca. 155 km2 in area (40,000 ac) and ranges in elevation from 1402 m to 3033 m. The study area is botanically diverse with more than 750 taxa documented, including 56 taxa of conservation concern and 81 non-native taxa. Vegetation and habitat types in the area include chaparral, evergreen oak forest and woodland, riparian forest, coniferous forest, montane meadow, and pebble plain habitats.

    Sierra Nevada Framework FEIS Chapter 3

    table of contrents Sierra Nevada Forest Plan Amendment – Part 4.6 4.6. Vascular Plants, Bryophytes, and Fungi4.6. Fungi Introduction Part 3.1 of this chapter describes landscape-scale vegetation patterns. Part 3.2 describes the vegetative structure, function, and composition of old forest ecosystems, while Part 3.3 describes hardwood ecosystems and Part 3.4 describes aquatic, riparian, and meadow ecosystems. This part focuses on botanical diversity in the Sierra Nevada, beginning with an overview of botanical resources and then presenting a more detailed analysis of the rarest elements of the flora, the threatened, endangered, and sensitive (TES) plants. The bryophytes (mosses and liverworts), lichens, and fungi of the Sierra have been little studied in comparison to the vascular flora. In the Pacific Northwest, studies of these groups have received increased attention due to the President’s Northwest Forest Plan. New and valuable scientific data is being revealed, some of which may apply to species in the Sierra Nevada. This section presents an overview of the vascular plant flora, followed by summaries of what is generally known about bryophytes, lichens, and fungi in the Sierra Nevada. Environmental Consequences of the alternatives are only analyzed for the Threatened, Endangered, and Sensitive plants, which include vascular plants, several bryophytes, and one species of lichen. 4.6.1. Vascular plants4.6.1. plants The diversity of topography, geology, and elevation in the Sierra Nevada combine to create a remarkably diverse flora (see Section 3.1 for an overview of landscape patterns and vegetation dynamics in the Sierra Nevada). More than half of the approximately 5,000 native vascular plant species in California occur in the Sierra Nevada, despite the fact that the range contains less than 20 percent of the state’s land base (Shevock 1996).

    Checklist of Ventura County Rare Plants (Twenty-second Edition) CNPS, Rare Plant Program David L. Magney Checklist of Ventura County Rare Plants1 By David L. Magney California Native Plant Society, Rare Plant Program, Locally Rare Project Updated 4 January 2017 Ventura County is located in southern California, USA, along the east edge of the Pacific Ocean. The coastal portion occurs along the south and southwestern quarter of the County. Ventura County is bounded by Santa Barbara County on the west, Kern County on the north, Los Angeles County on the east, and the Pacific Ocean generally on the south (Figure 1, General Location Map of Ventura County). Ventura County extends north to 34.9014ºN latitude at the northwest corner of the County. The County extends westward at Rincon Creek to 119.47991ºW longitude, and eastward to 118.63233ºW longitude at the west end of the San Fernando Valley just north of Chatsworth Reservoir. The mainland portion of the County reaches southward to 34.04567ºN latitude between Solromar and Sequit Point west of Malibu. When including Anacapa and San Nicolas Islands, the southernmost extent of the County occurs at 33.21ºN latitude and the westernmost extent at 119.58ºW longitude, on the south side and west sides of San Nicolas Island, respectively. Ventura County occupies 480,996 hectares [ha] (1,188,562 acres [ac]) or 4,810 square kilometers [sq. km] (1,857 sq. miles [mi]), which includes Anacapa and San Nicolas Islands.
