This shapefile shows the four proposed Areas of Critical Environmental Concern (ACEC), present in Alternative C, only, each of which is proposed because the habitat supports the federally proposed Gila chub. ACECs are a type of Special Area Designation. One of the four areas, Lousy Canyon, also contains the federally listed Gila topminnow and desert pupfish. For clarity, alternatives B and D are also included, attributed as "not allocated." From the alternatives, one set will be selected to be proposed as the geographic area to which particular management actions will be applied, to manage the resource upon adoption of the Resource Management Plan (RMP).
This shapefile contains RMP Alternatives for the Agua Fria National Monument only. Overall, the RMP Alternatives comprise Alternative A, also known as the no-action or current management alternative, and four action alternatives: Alternative B, which plans for increased public use while ensuring resource protection; Alternative C, which provides visitors with opportunities to experience the natural landscapes and cultural resource setting of the Monument, generally with more restrictive decisions than Alternative B; Alternative D, which emphasizes the preservation of undeveloped, primitive landscapes on the Monument, resulting in limited public use and the withdrawal of authorized grazing; and Alternative E, the preferred alternative.
In a particular alternative, the key "alternative (e.g. Alt A) attribute" has a domain that represents the several possible designations for each polygon. A particular polygon is assigned the designation that planners deemed appropriate. For this resource, if a particular area is a place where this resource will not be one of the "multiple uses" of the land, the designation is "not allocated." The entire "allocation" of the resource in each alternative is the sum of the acres, throughout the extent, for which the land has a management designation (other than "not allocated").
This data set was prepared for use in the BLM Phoenix Field Office (PFO) Agua Fria National Monument and Bradshaw-Harquahala planning areas Resource Management Planning (RMP) process. The RMP process was initiated by the publication of the Notice of Intent (NOI) in the Federal Register on April 24, 2002 (67 FR 20148), and was ongoing when the consultant (Jones & Stokes) datasets were submitted to BLM PFO in March, 2004. The shapefile is intended for regional analysis and display at a scale of 1:24,000. Abstract and corresponding spatial domain (extent) indicate the area covered by the shapefile, within or outside the planning areas.
