Vegetation types associated with meadows and wetlands (California Wildlife Habitat Relationship type “WTM” [wet meadow] and “PGS” [Perennial Grassland]) are queried and enumerated from the most recently available vegetation map (U.S. Forest Service - Remote Sensing Lab Pacific Southwest Region: TMU_Strata_07 [published 2009]). The Tahoe vegetation map is periodically updated with new satellite data (if available) and/or modelled and calibrated using field-based forest inventory and analysis data to assess the extent of different vegetation types and associated forest structure characteristics for the Region (USDA, 2009; Warbington et al., 2011).
