Click on image to enlarge (135K). Click here to display a larger version (380K).The image above shows USFS vegetation stand types for the Berry Gulch Calwater planning watershed, which is the same as the Little North Fork Big River basin, based on a 1994 Landsat image. The stand types are only accurate at the one-hectare scale. Patches of the basin show as Non-Forest and Saplings (<5" diameter trees), likely as a result of recent clear cuts. Young forest shows as Small and Small/Medium trees. See Info Links for more information. Taken from the KRIS Big River Map project.
