Timber Harvesting Plans (THPs) approved by the California Department of Forestry and Fire Protection, permitting timber harvest for commercial purposes on non-federal lands. Data and feature representations contribute to assessment of cumulative effects from timber harvesting in planning watersheds and support the planning, regulation, enforcement, and oversight of commercial timber harvesting on non-federal lands in California. For more information, see Subchapter 7, Article 2, Timber Harvesting Plan, of the California Forest Practice Rules. Data from 1997 to present. This data set is in the California Teale Albers NAD83 meters projection (TA83).
