Locating potential places to increase representation is typically done by a systematic selection algorithm over a set of spatial units larger than the landscape units of the vegetation map. The landscape is thus the basic spatial unit at which biodiversity data are compiled for Gap Analysis. However, it is only one of four levels of spatial entity that must be explicitly defined in order to complete a Gap Analysis. We refer to these entities as the planning region, the planning unit, the landscape, and the landscape feature. The objective of this paper is to describe a spatial analytical hierarchy for Gap Analysis based on these four entities. Within this broader theme we also present results of a more focused analysis on the effect of planning unit size on the selection of priority conservation areas in southwestern California. %B Gap Analysis: A Landscape Approach to Biodiversity Planning %I American Society for Photogrammetry and Remote Sensing %C Bethesda, MD %P 15-24 %G eng %0 Book Section %B Gap Analysis: A Landscape Approach to Biodiversity Planning %D 1996 %T A spatial analytical hierarchy for Gap Analysis %A Davis, F.

M. %K habitat suitability %K sensitivity analysis %X Observation and habitat data were compiled and analyzed in conjunction with recovery planning for the endangered California Condor (Gymnogyps californianus). A geographic information system (GIS) was used to provide a quantitative inventory of recent historical Condor habitats, to measure the association of Condor activity patterns and mapped habitat variables, and to examine spatio-temporal changes in the range of the species during its decline. Only five percent of the study area within the historic range is now used for urban or cultivated agricultural purposes. Observations of Condor feeding perching, and nesting were nonrandomly associated with mapped land cover, in agreement with life history information for the species. The precipitous decline in numbers of Condors in this century produced only a small reduction in the limits of the observed species 'range, as individual birds continued to forage over most of the range. Some critical risk factors such as shooting and lead poisoning are difficult to map and bave not been included in the database Besides the applications demonstrated in this case study, GIS can be a valuable tool for recovery planning, in the design of stratified sampling schemes, or for extrapolation of habitat models over unsurveyed regions. We conclude with recommendations from this case study regarding when to consider using GIS and the importance of pilot studies and sensitivity analysis. %B Conservation Biology %V 7 %P 148-159 %8 1993 %G eng %U ://A1993KR98600021 %0 Book Section %B Challenges in the Conservation of Biological Resources: A Practitioner's Guide %D 1991 %T Gap analysis: an application of Geographic Information Systems for wildlife species %A Scott, J.
