Title: DEVELOPING A SUITABILITY MODEL FOR CONSERVATION PRIORITIZATION: THE PARCEL PICKER |
Abstract/Description: An analysis tool has been developed by The Nature Conservancy (TNC) to aid staff in the preliminary site planning process by prioritizing parcels for protection. The tool, dubbed ‘The Parcel Picker’, is a spatially-enabled extension for the ArcGIS® ArcMap application, a popular GIS program produced by Environmental Systems Research Institute. The extension utilizes a spatial analysis technique commonly referred to as a Weighted Linear Combination, where various factor maps are weighted and combined to produce a relative suitability score. Individual parcels can then be assigned a single suitability score. Users can choose inputs from the provided list of factors, all related in some manner to targets and threats, and produce an output map of priority areas based on a subjective assignment of weights. This process can be performed multiple times using various weighting schemes, thus allowing evaluation of the effects of different combinations of factors and weights. An important component of the model is that full documentation is written into the output itself which describes the data and weighting scheme used. Because the model is based on user-defined values and accepts an array of input datasets, the tool can be used across multiple regions.
