Geospatial Tools for Analysis MARXAN (SPEXAN) www. ecology. uq. edu. au/marxan. htm Developed by S. Andelman, I. Ball, F. Davis, D. Stoms National Center for Ecological Analysis and Synthesis Santa Barbara, California Site Selection Module developed by I. Ball and H. Possingham University of Adelaide, Australia Channel Islands Spatial Support and Analysis Tool (CI-SSAT) www. csc. noaa. gov/pagis Developed by NOAA’s Coastal Services Center

Developing Reserve Designs MARXAN (SPEXAN) • Develops a portfolio of reserve designs that meet particular targets. • Uses simulated annealing to develop a large number of alternative designs. • Attempts to minimize the total cost (boundary length) of the reserve network. • Allows the analyst to control the spatial configuration of the reserve designs.
