I am looking for a tool in ArcGIS to help in identifying priority areas for conservation based on the output of species distribution models (maxent, GLM, BRT,..). Something maybe similar to the zonation algorithm.
This website has links to dozens of connectivity tools https://conservationcorridor.org/corridor-toolbox/programs-and-tools/
FunnConn and Linkage Mapper both run in ArcGIS. Others run in R or are stand-alone tools. Each has its own assumptions about which patches are "better" so whichever one you choose to use you'll want to read up on it quite a bit. I'd start from what you want the tool to do rather than the software that you want to run it in. Many of these are open source and are freely downloadable.
