Coupling modeling landscape graph and biological data

Landscape mapping is widely used to model habitat patch networks. Because little input data is required, these methods are particularly well suited to support land planners’ decisions. However, if these methods are not validated with empirical data from species or communities, their use in an operational environment may be problematic. For this, Paul Savary proposed a coupling modeling method of landscape graph and biological data. This method is mainly used to simulate the patch network of discrete habitats of many species and many geographical environments. In these charts, nodes usually represent patches of habitat for the species under study, and links represent potential migrations. According to the original design, the landscape graph was constructed from a landscape map defined by the species’ habitat needs and mobility. The fact that landscape maps are complemented by landscape maps representing a range of potential habitat patches is another reason to encourage this coupling.
