Timber Production Zone Lands

This layer was created to show lands taxed as 'Timber Production Zones (TPZ)' timberlands across the NCRP region of the Northern California area of California. For Sonoma, Trinity, Del Norte, Siskiyou, Humboldt, Mendocino, and Modoc Counties, TPZ parcels were identified from county parcel and zoning datasets. Once the TPZ parcels across the region were identified, they were merged together. Areas mapped in the 2022b California Protected Areas Database as public lands (along with a 60 meter buffer on these lands) were removed from the TPZ layer.
