Maxent software for species habitat modeling

Most current version: 3.3.3k (see new features below).

Use this site to download software based on the maximum-entropy approach for species habitat modeling.  This software takes as input a set of layers or environmental variables (such as elevation, precipitation, etc.), as well as a set of georeferenced occurrence locations, and produces a model of the range of the given species.

Further description of this approach can be found in:
