Abstract:
These data represents those polygons included in BLM Resource Management Plans in Arizona to be managed to maintain existing wilderness characteristics. Characteristics of wilderness; including outstanding opportunities for solitude, naturalness, and outstanding opportunities for primitive and unconfined recreation; have been inventoried and have been determined to exist in these areas, and the areas have been determined to be managable to maintain these characteristics, while also meeting the mandate of the Federal Land Policy and Management Act of sustained yield and mulriple use. |

These data represents those polygons included in BLM Resource Management Plans in Arizona to be managed to maintain existing wilderness characteristics. Characteristics of wilderness; including outstanding opportunities for solitude, naturalness, and outstanding opportunities for primitive and unconfined recreation; have been inventoried and have been determined to exist in these areas, and the areas have been determined to be managable to maintain these characteristics, while also meeting the mandate of the Federal Land Policy and Management Act of sustained yield and mulriple use.
For regional analysis and display at 1:45,000. This dataset was prepared/acquired for use in resource management planning processes in various BLM offices throughout Arizona. These data establish a layer that spatially represents those acres that contain the wilderness characteristics of naturalness, solitude, and primitive/unconfined recreation, and have been selected to be included as an allocation to maintain those characteristics in Resource Management Plans.
Data has been compiled by each field office completing a Resource Management Plan after about 2004. Various methods were used to compile the data and any specifics about any particular polygon or attribute should be directed to the local BLM field office having jurisdiction.
ground condition
This data should not be used at a scale larger than 1:45,000. The data and corresponding attributes are only as accurate as the source maps from which they were obtained, and may vary depending on the data and method of acquisition. This data is suitable for regional planning, management decision support at intermediate scales (i.e. 1:45,000 or smaller), and cartographic purposes. The data is not suitable for analysis at scales larger than 1:45,000. If the Receiving Agency (RA) has modified the data in any way, they are obligated to describe the types of modifications they have performed on hardcopy maps utilizing the data. RA specifically agrees not to misrepresent ASDOGID datasets or to imply that any changes made were approved by BLM ASDO or NPS. No warranty is made by the BLM/NPS for use of the data for purposes not intended by BLM/NPS. This information may be updated without notification.

Feature attributes were taken from source material. Code assignments are believed to be representative of the source document.
Data was reviewed for correct topological structure. Duplicate lines have been removed.
This dataset covers BLM field offices with recently completed Resource Management Plans.
The data was developed by screen digitizing polygons using a variety of field maps, photos, and other data sets. Coarse polygons were drawn in the field on maps printed with land status, transportation, and 1:24,000 or 1:100,000 digital raster graphs (DRG). These field maps were drawn to correspond with the wilderness characteristics evaluations that were written while in the field. In the office, information on the field maps was screen digitized using the same data sets in the background that were used in the field maps. Horizontal accuracy is not greater than 1:45,000. Positional accuracy was tested by visual comparison of the source data with the hard copy field maps.
The data set was developed as part of identifying areas where wilderness characteristics would be maintained.
Field data collected and presented by the Arizona Wilderness Coalition (AWC) were reviewed.
One North Central, Suite 800
Field trips were made to evaluate the AWC proposal. Notes were taken, photos were taken, and evaluations were written.
In the office, polygons were screen digitized to correspond with field collected data. This resulted in the data sets wild_nat, wild_sol, and wild_primrec, which represent the wilderness characteristics of naturalness, solitude, and primitive/unconfined recreation. These data were then analyzed by staff and used to create the data set lwc (lands with wilderness characteristics).
The alternative development process was then used to create this data set. This process is described in detail in the Arizona Strip DEIS, Appendix 3D, beginning on page 6.
Original digital data file was created by local GIS staff by converting mwc_alte data to reflect proposed plan changes resulting from public review and comment.

Defines the geographic name assigned to each unique wilderness characteristic unit.
Defines the total numeric value placed on an individual wilderness characteristic unit. The criteria values are as follows: 1. Overlaps with an additional (third) wilderness characteristic polygon. 12 points; 2. Is contiguous to an existing designated wilderness or an NPS proposed wilderness area. 8 points; 3. Any portion of the polygon area is coincidental with a corresponding Semi-Primitive Non-Motorized ROS polygon. 5 points; 4. Contains listed species or other critical T and E plant/wildlife habitat that would be enhanced/protected by MWC status. 3 points; 5. Contains known cultural sites or areas that would be enhanced/protected by MWC status. 2 points; 6. Any portion of the polygon area is coincidental with VRM inventory class 2. 2 points; 7. Contains specific geologic, biologic, or other natural features that are distinctive or exceptional. 2 points
Defines the risk level of each individual wilderness characteristic polygon. Example: the closer the polygon to an urban interface, the greater the risk of losing those wilderness characteristics. A yes answer to any of the statements in this section results in the listed point total for that statement: 1. This area is considered to be at high risk. This may be due to one or more of the following conditions: -a.- The area is in close proximity to a community interface zone (generally less than ten miles) -b.- The area is outside national monument, existing ACEC boundaries, other protective withdrawals, or special designations. -c.- The topography is generally low relief and/or has large sections along the boundary that are conducive to unauthorized motorized access. -d.- The area has high potential for increased visitation over the next twenty years.10 points; 2. This area is considered to be at moderate risk. This may be due to one or more of the following conditions: -a.- The area is within moderate proximity to a community interface zone (generally between 10 and 25 miles); -b.- The area may be either inside or outside national monument, existing ACEC boundaries, other protective withdrawals, or special designations. -c.- The topography is generally low to moderate relief and/or has some sections along the boundary that are conducive to unauthorized motorized access. -d.- The area has moderate potential for increased visitation over the next twenty years. 6 Points; 3. This area is considered to be at low risk. This may be due to one or more of the following conditions: -a.- The area is a considerable distance from a community interface zone (generally more than 25 miles) -b.- The area may be either inside or outside national monument, existing ACEC boundaries, other protective withdrawals, or special designations. -c.- The topography is generally moderate to high relief and/or has few sections along the boundary that are conducive to unauthorized motorized access. -d.- The area has low potential for increased visitation over the next twenty years. 3 Points; 4. This area is considered to be at low risk. This may be due to one or more of the following conditions: -a.- The area is a considerable distance from a community interface zone (generally more than 25 miles) -b.- The area is inside a national monument, existing ACEC boundary, other protective withdrawal, or special designation. -c.- The topography is generally moderate to high relief and/or has no sections along the boundary that are conducive to unauthorized motorized access. -d.- The area has very low potential for increased visitation over the next twenty years.1 Point
Defines the manageability level of each individual wilderness characteristic polygon. Example: a polygon that has few natural barriers to motorized intrusion would have a lower manageability score. A yes answer to any of the statements in this section results in the listed point total for that statement.
