Graphab software is devoted to the modelling of ecological networks from the framework of graph theory. It is the only tool able to include construction and visualization of graphs, connectivity analyses and links with external data. It is easily compatible with Geographical Information Systems”.

“Land cover changes resulting from urban sprawl, transport network intensification and agricultural changes contribute to fragment wildlife habitats and may lead to question viability of animal and vegetal populations. Including issues of ecological networks and landscape connectivity in spatial planning and land management proves therefore to be a crucial stake for preserving biodiversity. In this context, the modelling of ecological networks is a suitable approach for achieving diagnoses, prioritizing action to be done (for instance ecological restoration) and comparing prospective scenarios of development or conservation. This kind of modelling is complementary to approaches led by field specialists in ecology”.
