CAL FIRE Nonindustrial Timber Management Plans and Notices TA83

Nonindustrial Timber Management Plans (NTMPs) and Notices of Timber Operations (NTOs) approved by the California Department of Forestry and Fire Protection for landowners with less than 2,500 acres of land not primarily engaged in the manufacture of forest products. NTMPs are living documents that do not expire, but may be withdrawn. 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 6.5, NTMP Administration, of the California Forest Practice Rules. Actual timber operations are conducted under NTOs. Data from 1991 to present. This data set is in the California Teale Albers NAD83 meters projection (TA83).
