Area	Upper Trinity
Topic	Map: 1I. Vegetation Change 1994-1998, Upper Trinity Sub-Basin

 

	This is a map of vegetation change for the years 1994-1998 in the Upper Trinity sub-basin above Trinity Lake, displayed with land ownership, the Trinity River, Trinity Lake, and sub-basins. Each block in the checkerboard pattern of land ownership is approximately one square mile. The orange/red colors in the vegetation layer show canopy losses of 16-100% over a 4 year period and indicate substantial timber harvesting (and possibly some wildfires) in the area. Data were provided by the U.S. Forest Service Spatial Analysis Lab in Sacramento, CA.
