    Vegetation - Lassen Foothills [ds564]

    Metadata Updated: March 23, 2026

    The Tehama County Resource Conservation District contracted with the California Native Plant Society (CNPS) and Aerial Information Systems (AIS) to produce a fine-scale, spatially and floristically accurate vegetation map of the Lassen Foothills project area. This area encompasses a 108,400 acre portion of eastern Tehama County and covers three large parcels: South Denny Ranch, Tehama Wildlife Area, and Dye Creek Preserve. The project area represents a biologically diverse mix of vegetation types including grasslands, riparian, foothill chaparral, and oak woodlands. Vegetation resources were assessed through new and previous field surveys, classification analysis of 35 vegetation alliances, and mapping of 37 vegetation map units. To validate the vegetation map, an accuracy assessment with field verification was conducted by CNPS field staff.

    The minimum mapping unit (MMU) for the study area is approximately 1/2 hectare. Small wetlands were delineated in many incidences below the MMU. The 1/2 hectare MMU applied for all floristic and structural breaks as required by the contract.

    More information can be found in the project report, which is bundled with the vegetation map published for BIOS here: https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/500_599/ds564.zip
