This package allows to perform the Ecological Niche Factor Analysis, calculate habitat suitability maps and classify the habitat in suitability classes. Computations are executed in a throw-away GRASS environment from R in order to be able to perform analysis with large data sets. 

Tools to generate random landscape graphs, evaluate species occurrence in dynamic landscapes, simulate future landscape occupation and evaluate range expansion when new empty patches are available (e.g. as a result of climate change).
