The image above shows USFS vegetation stand types for the riparian zone of the Billings Creek Calwater planning watershed based on a 1994 Landsat image. The stand types are only accurate at the one-hectare scale and the buffer width is 90 meters. Much of the riparian shows as Non-Forest, Saplings and Small Trees as a result of Central Belt Franciscan geology which gives rise to natural grasslands and oak woodlands. Although some Saplings (<5" diameter) may be in part associated with grasslands, in combination with Small Trees (5-11" diameter), they may also represent some areas of recent timber harvest. See Info Links for more information. Taken from the KRIS Gualala Map project.

Very little of the riparian zone of the Billings Creek Calwater showed timber harvest effects between 1994 and 1998 according to Landsat images as derived by the California Department of Forestry FRAP division. From the KRIS Gualala Map project
