The original CBI Protected Areas Database was the product of a collaborative effort between the Conservation Biology Institute and World Wildlife Fund, USA. This Second Edition of the PAD represents an updated version of the first database, and contains boundaries of most federal and state owned/managed protected areas in the coterminous United States and Alaska, and includes county, city, and private reserves when data were available. The database also contains boundaries of all provincially owned protected areas in Canada. Protected areas are defined as parcels with a Gap Analysis Program (GAP) code of 1, 2, 3, or 4. We added an additional GAP code of “5” to designate bodies of water. (Please note that MN GAP has assigned some additional GAP codes which are described in their metadata file). The database also contains information about parcel type, ownership, size, and protection level.

Gap Analysis Program (GAP) code indicating level of protection for each parcel under the GAP criteria
| Value | Definition |
|---|---|
| 1 |
Area has an active management plan in operation to maintain a natural state and within which natural disturbance events are allowed to proceed without interference or are mimicked through management |
| 2 |
Area is generally managed for natural values, but may receive use that degrades the quality of existing natural communities |
| 3 |
Most non-designated public lands. Legal mandates prevent the permanent conversion of natural habitat types to anthropogenic habitat types and confer protection to populations of Federally listed endangered and threatened species. |
| 4 |
Private or public lands without an existing easement or irrevocable management agreement to maintain native species and natural communities and which is managed for intensive human use. |
| 5 |
This is not a standard GAP code. We used this code to classify open bodies of water (e.g. lakes, ponds, reservoirs) for which GAP protection was unknown. |

This dataset was created to provide natural resource managers with a large-scale digital dataset that can be used to assess the protection status of natural ecosystems and individual biodiversity elements throughout the United States and Canada.
The CBI Protected Areas Database was developed from many existing datasets. However, most work was done on a state-by-state basis and then combined to produce the final PAD. Statewide coverages were developed using the following procedures: For each state, all the relevant datasets were combined using the UNION command. Linework was cleaned up, sliver polygons removed, and labelerrors corrected. Attributes for the CBI PAD (see Entity_and_Attribute_Information) were added and all others were removed. The finished statewide datasets were re-projected from the source projection into Lambert Azimuthal (see Spatial_Reference_Information for specific parameters). Protection codes (GAP and IUCN) were assigned to each parcel in every statewide coverage and Canadian province. GAP Codes National Gap Analysis Program (GAP) codes were assigned to each polygon in every statewide coverage in the following manner. Existing GAP codes were used when these were available from the GAP Program. The following states had existing GAP codes: Arizona Arkansas California Colorado Florida Georgia Idaho Illinois Indiana Iowa Kentucky Louisiana Maine Michigan Minnesota Missouri Montana Nevada New Mexico North Carolina Oklahoma Oregon Pennsylvania Tennessee Utah Virginia West Virginia Wyoming GAP codes for the remaining states were assigned according to criteria defined by the National GAP Program (Scott et al. 1993). Because there was no practical way to contact each manager of every protected area to determine management practices, we were forced to assign protection levels categorically by parcel designations. In general, codes were assigned in the following manner: GAP CODE DESIGNATIONS ******************************************************************************** 1 National Park, National Monument, Wilderness Area, Nature Reserve/Preserve, Research Natural Area 2 State Parks, State Recreation Areas, National Wildlife Refuge, National Recreation Area, Area of Critical Environmental Concern, Wilderness Study Area, Conservation Easement, Private Conservation Land, National Seashore 3 BLM Holdings, Military Reservations, National Forests, State Forest, Wildlife Management Areas, Game and Fish Preserves, Fish Hatcheries, State Commemorative Area, Access Area, National Grassland, ACOE Holding 4 Private Land, Tribal Land, City Park, Undesignated State Land, County Land, City Land There were hundreds of different designation types in the statewide coverages. Designations not mentioned above were assigned GAP codes determined by the usual management strategy for that land type. We consulted state officials when we were unsure of the management status of a given designation type. In some cases, we were unable to determine the management type for a given designation using the above strategies. In these cases, we assigned a GAP code by consensus of several CBI scientists who are knowledgable about land use issues within the U.S. The WWF Canada dataset had existing IUCN codes assigned to the polygons. We assigned GAP codes in the following manner: IUCN categories I-III corresponded to GAP code 1; IUCN categories IV and V corresponded to GAP code 2; and IUCN category VI was assigned a GAP code of 3. IUCN Codes For the United States, we assigned IUCN codes based on the IUCN's categories for conservation management (IUCN 1994). In general, parcels with a GAP code of 1 corresponded to IUCN categories I-III; GAP code 2 corresponded to IUCN categories IV and V; some GAP code 3 parcels corresponded to IUCN category VI, while others with intensive extractive uses (e.g. National Forest) are not covered under the IUCN's conservation management categories, and therefore did not receive an IUCN code. The WWF Canada dataset came with IUCN codes already assigned and we used them as they appeared. Additionally, a subset consisting of the southern and eastern states of the PAD was selected with ArcGIS 8.2.

Acknowledgement of products derived from this data set should cite the following: The Conservation Biology Institute's Protected Areas Database (PAD), Second Edition The individual source(s) for the portion of the data used (available by state). The data used to compile the finished database came from a variety of sources and were produced at different map scales. Most of the data were at a scale of 1:100,000 or finer. Therefore, this dataset can be used appropriately for coarse-scale analyses at the state or ecoregion level. Appropriate uses include: Statewide biodiversity planning Regional planning or biological assessments Coarse-scale (e.g. national) evaluation of ecosystem representation within existing protected areas Inappropriate uses include: Resource planning at a scale smaller than statewide Establishing exact legal boundaries of protected areas Establishing definite presence or absence of any protected area Determining exact areas for parcels
