occ.landscape

Sample random landscape graph, with species occupancy data (occupancy rate - 50%). Simulated data.

datasets

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). References: Mestre, F., Canovas, F., Pita, R.,
