CorridorDesigner includes an ArcToolbox toolbox for creating habitat and corridor models with ArcGIS and an ArcMap extension for evaluating corridors. All tools and supplentary materials are works in progress, and undoubtedly contain bugs, typos, and other occasional screw-ups. If you experience a problem with the tools, please send us an email so we can help you figure out how to fix it. Also, a lot of great tools have been created since we started this website in 2007. Don't forget to check out our resources page to find tools that might better meet your needs.

The CorridorDesigner toolbox aids the user in 1) creating habitat suitability models & identifying potential habitat patches, 2) creating corridor models, and 3) transforming a DEM into a topographic slope position raster. The CorridorDesigner toolbox currently only works within ArcCatalog, not ArcMap, and requires all data to be in the same meters (UTM) projection.

Important! If you're having problems with the toolbox, here are some common errors and solutions.
The Arizona CorridorDesigner toolbox provides an easy entry point to the corridor design process for those performing corridor analyses within the state of Arizona, USA. It provides parameterized models for 25 species modeled in the Arizona Missing Linkages project, including bighorn, pronghorn, mountain lion, desert tortoise, black bear, black-tailed jackrabbit, elk, mule deer, javelina, coati, and others.
The Arizona CorridorDesigner toolbox includes the general CorridorDesigner toolbox available separately above. In order to use the Arizona toolbox, you must also download the GIS dataset which works in conjunction with the tools. If you already have a 30m DEM, a roads shapefile, and an ownership/stewardship file for Arizona in NAD UTM z12 projection, you can just download the customized land cover layer. Otherwise, you should download the full GIS dataset.

The ArcMap extension allows the user to evaluate and compare alternative corridor designs by calculating metrics such as: 1) Width and bottlenecks throughout a corridor, 2) Distances between habitat patches within a corridor, and 3) General statistics such as histograms of habitat suitability within a corridor. The CorridorDesigner evaluation extension is designed to work with the output from the ArcGIS extension to evaluate potential wildlife corridors.
