CAL FIRE Forest Practice Roads TA83

Road features mainly derived from plans approved by the California Department of Forestry and Fire Protection. Features include both public and private roads. For information on classifications, see the California Forest Practice Rules. Data do not represent the complete roads network. Existing roads within the harvest area which are not being utilized for timber harvesting are not required to be mapped as part of a plan, and therefore may not be included. Skid trails and tractor roads are not included. Not all roads within a given plan’s harvest area are necessarily in use under that plan and may be associated with a previous plan. Refer to maps submitted with plans on the CalTREES website for clarification on a specific plan’s roads. Data from 1983 to present, but primarily from 1997 onward. This data set is in the California Teale Albers NAD83 meters projection (TA83).
