Data Set Identity: ma
Description:
Land ownership and management of California, distinguishing local, state, and federal jurisdictions from private lands and delineating areas managed for the long-term maintenance of natural ecological processes and biodiversity. This layer therefore contains attributes both for ownership and for the level of biodiversity protection.

Completeness Report:
Base land ownership derived from BLM 1:100,000 scale map sheets. Additional land ownership updated from various sources on published or agency maps. Managed areas added from paper and digital sources from the responsible agency. Set of managed areas incorporated based on lists in Kreissman, B. 1991. California: An Environmental Atlas and Guide. Bear Klaw Press, Davis, CA. Additional managed areas identified from more recent legislation and agency contacts. Managed areas smaller than 200 hectares for upland sites and 80 hectares for wetland sites were not included on the assumption that they contribute little to regional biodiversity conservation. However, where digital map boundaries were readily available, these smaller sites were incorporated as well, but were labeled as a special management level.
Some managed areas are nested within others. Because only one code is permitted per map unit, the one with the highest level of protection is encoded. This means that it may not be straightforward to extract or reselect all areas of a particular category. For instance, some Forest Service Research Natural Areas (RNA) are within Wilderness Areas. To extract all wilderness from the database, a user would have to know which specific RNA's, condor sanctuaries, etc. occur within wilderness.

Source Information:
The ownership data were derived from the 1:100,000 scale Bureau of Land Management Surface Management Status maps. The most recent national forest maps and other sources were used to update the BLM maps prior to digitizing. The managed area boundaries were compiled from many sources. Many larger areas could be found on the USGS 1:100,000 scale topographic maps revised in the 1980s. Fish and Game Ecological Reserves and Wildlife Areas and Nature Conservancy Preserves were provided as digital files from the California Department of Fish and Game's Heritage Program. ARC/INFO coverages of the Santa Monica Mountains National Recreation Area, BLM Areas of Critical Environmental Concern and some other managed areas were obtained from the responsible agency. USFS wilderness area boundaries were obtained from published and unpublished Forest Service maps. The wilderness areas and park designations in the California Desert Conservation Act of 1994 were obtained from the 1991 digital GIS coverage prepared by the BLM state office. Various paper maps were used to delineate state wildernesses and all other managed areas.

Source Distance Resolution (meters): 50
Process Description:
The ownership data were originally digitized by the Forest and Rangeland Resources Assessment Program of the California Department of Forestry and Fire Protection. It was then registered to the Public Land Survey coverage at Teale Data Center so that coincident linework was common. Land owner information was included as an attribute.
Managed areas were incorporated into this base coverage at UCSB. Some boundaries were merged from existing digital coverages (see Source Information above). Others were transcribed from paper maps onto USGS 1:100,000 scale topographic maps and digitized. Attributes were added for the source of data, management status, and a 10 character Heritage Program ID-code for managed areas. For further details, see:

INFO Filename: MA.PAT INFO Item: STATUS
STATUS | DESCRIPTION |
1 | An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a natural state within which disturbance events (of natural type, frequency, and intensity) are allowed to proceed without interference or are mimicked through management. (Fire is usually suppressed in most managed areas in California, however). |
2 | An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a primarily natural state, but which may receive use or management practices that degrade the quality of existing natural communities. |
3 | An area having permanent protection from conversion of natural land cover for the majority of the area, but subject to extractive uses of either a broad, low-intensity type or localized intense type. It also confers protection to federally listed endangered and threatened species throughout the area. |
4 | Lack of irrevocable easement or mandate to prevent conversion of natural habitat types to anthropogenic habitat types and allow for intensive use throughout the tract, or existence of such restrictions is unknown. |
