The image above shows USFS vegetation stand types for the Dark Gulch Calwater planning watershed based on a 1994 Landsat image. The stand types are only accurate at the one-hectare scale. Large patches of Non-Forest and Saplings (<5" diameter trees) occur throughout the basin areas are likely the result of timber harvest. Medium-Large Trees (20-29.9") occur in patches in upper Gates Creek. Patches of young forest show as extensive patches of Small and Small/Medium trees. See Info Links for more information. Taken from the KRIS Big River Map project.

The image above comes from the KRIS Big River Map project and shows changes in vegetation between 1994 and 1998 according to CDF FRAP change scene detection. Not much of the South Fork Big River watershed experienced appreciable loss of canopy except for the western Mettick Creek CalWater. One patch in northeastern Dark Gulch CW also shows result of timber harvest between 1994 and 1998.
