Abstract
GIS-based siting procedures are progressively used to select protected areas (PAs) on the basis of a variety of attributes clustered in main environmental groups including climate, hydrogeology, vegetation cover and various criteria and sub-criteria showing changes in the landscape. However, the suitability of a selecting procedure may be restrained by the aggregate analyses involving the weight and relative importance of the criteria. Here, we integrate a multi criteria decision analysis methodology with geographic information system for selecting a protected region for the vulnerable Kaiser's mountain newt, Neurergus kaiseri, endemic to southern Iran. The process of decision making for selection a PA for N. kaiseri structured in a two-stage. Mask maps are prepared using nine exclusionary criteria including stream density, high ridge density, areas with unsuitable terrestrial vegetation cover, unacceptable land use, harsh climate, inappropriate distance to cities and industries, main roads, railroad, and dam reservoirs. These exclusionary criteria provided an overlay map representing areas grossly suitable for allocating PAs. The initial site screening followed by a multi criteria decision analysis based on ten non-exclusionary criteria including conservation integrity, number of newt localities, MaxEnt suitability score, distance to nearest neighbor habitat, genetic diversity, spring density, distance to protected area, extent of selected patch areas, villages density and distance to main roads. Giving weight and rate to the non-exclusionary criteria all nominated PAs received a numerical evaluation.
