- Relative Abundance of Red Fir Forest In Seral Stages Other Than Mature

- Each Unit (number)
-
Of the total amount of undisturbed vegetation in the Tahoe Basin maintain 15 to 25 percent of the red fir forest in seral stages other than mature.
- Relative proportion of yellow pine and red fir forest tree stands dominated by small diameter trees less than 10.9-inches diameter at breast height.
- This Indicator is reported in the following LT Info areas:
Estimated percent cover of red fir forest, displayed in light red on the chart, as tree size-class <11 inches diameter at breast height. Data is from LTBMU EcObject, a forest-wide Region 5 Remote Sensing Lab vegetation data set that incorporates Light Detection and Ranging (LiDAR) into the mapping process. It is created from a multi-resolution segmentation of LiDAR-derived tree approximate objects and a 1-m canopy height model, which were then aggregated by stand and tree-level ecologic relationships.

Approach
For this evaluation, stands dominated by trees less than 10.9-inches diameter at breast height (dbh) were enumerated from the following California Wildlife Habitat Relationship (CWHR) Types (CWHR, 2011) attributed in the U.S. Forest Service - Remote Sensing Lab Pacific Southwest Region TMU_Strata_07 map layer (published 2009). Every five years, the Tahoe vegetation map is updated with new satellite data (if available) and/or modeled 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).
