| Arizona Gap Analysis Project | |
| 2002 Full Book | |
Throughout this country, many public and private groups are assessing the status of biodiversity. Most of their efforts deal with local to countywide scales because of the difficulty of dealing with large landscapes. Gap analysis attempts to examine biodiversity status on a statewide scale. This report is the result of a multi-agency effort to gather information on biodiversity of Arizona then organize it into a Geographic Information System (GIS). The analysis reflects the status of the state during the early 1990s. "Gap Analysis" refers to the evaluation of the protection status of plant communities and vertebrate species richness by overlaying biological distribution onto a land ownership map. After compiling this statewide database, GIS tools are used to identify portions of the state that have both high biodiversity and low protection. Even though the GAP data are of low resolution, and in most cases, will not accurately characterize small-scale land management units, they can be used to target areas of the state for immediate protection or more thorough study. The Gap Analysis approach helps managers and conservationists to be proactive about landscape management and produces a set of data that should assist cooperative efforts in protection of biodiversity |
