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.
