This layer depicts montane meadow vegetation on National Forests in the Sierra Nevada range. Meadows are wet and dry grassland types and short emergent meadow types maintained by man-made dams. Vegetation consists of a mixture of grasses, perennial herbs, rushes, and sedges. Woody vegetation is typically associated with riparian meadows. Riparian vegetation can be shrub or tree form, such as willow, alder, cottonwood, and aspen types. Meadow types are coded as wet or dry, with or without woody vegetation, or short emergent wetland. Meadow polygons are mapped to a minimum of 5 acres. California Vegetation (CALVEG) types within a meadow polygon are mapped to a minimum of 2.5 acres.
This dataset is a compilation of native grassland vegetation from the California Gap dataset and CALVEG (WHRTYPE = PGS). In this Existing Vegetation tile, the CALVEG classification system was used for vegetation typing and cross-walked to other classification systems in this database. The USGS Land Use / Land Cover Anderson 1 classification system was also used. Mapping standards meet requirements of the USDA Forest Service (FS) as defined by the FS GIS data dictionary, FGDC Vegetation standards, FS Existing Vegetation Classification and Mapping Technical Guide. Regional add-ons are retained for the California Wildlife Habitat Relationship System (CWHR). This layer also contains polygons for Sequoia and Kings...
