Program
Each Unit (number)
1. Of the total amount of undisturbed vegetation in the Tahoe Region – maintain at least four percent deciduous riparian vegetation
2. A non-degradation standard to preserve plant communities shall apply to native deciduous trees, wetlands, and meadows while providing for opportunities to increase the acreage of such riparian associations to be consistent with the SEZ threshold.
Percent of the “undisturbed” vegetation dominated by deciduous riparian vegetation.
This Indicator is reported in the following LT Info areas:
Status

Estimated percent of land area occupied by deciduous riparian vegetation in the Lake Tahoe Region relative to TRPA adopted numeric target (blue line). Changes in the percent cover are a result of different interpretations of the baseline amount of undisturbed vegetation and changing mapping techniques/resolution, not necessarily actual changes in vegetation type.

General

Program Deciduous Riparian Vegetation Monitoring

Approach

Vegetation types associated with deciduous riparian vegetation (montane riparian, aspen, and mix hardwood/conifer) were 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 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).
