LSCorridors v. 1.0.0 is now released!
LandScape Corridors (LSCorridors) is a free software package which aims to model multiple possible ecologically functional corridors between large sets of source and target areas at once, in order to maximize the possibilities for species movement. LSCorridors introduces a new approach for ecological corridor design by including 1) stochastic variation in the resistance surface and 2) landscape influence on organismal perception in the simulations. LSCorridors is Python-based and runs within GRASS GIS environment.
