Do you want to design a corridor within one habitat type? Then our tools and methods probably won't help you too much. How about a 30-m urban greenway? Again, GIS modeling might not be the best approach. Our methods, together with the CorridorDesigner ArcGIS tools, are best suited for designing corridors in a heterogenous landscape at a regional (e.g. 2 - 500 km long) scale. We have found GIS-based corridor modeling to be a useful tool which helps us design the best corridors we can, but it's certainly not the only game in town!
