Tree species diversity distribution

How to use the r.series.diversity addon for GRASS GIS to generate maps of the tree species diversity across the contiguous USA. tags: GRASS GIS, biodiversity, biogeography

This short tutorial shows how to use the r.series.diversity addon for GRASS GIS to compute the tree species diversity distribution patterns in the contiguous USA, based on tree distribution data from Barry Tyler Wilson et al. (2013). It shows how to compute a number of diversity indices, including the Renyi entropy index and a number of specialized cases of the Renyi enthropy, viz.the species richness, the Shannon index, the Shannon based effective number of species (ENS), the Simpson index (inverse and gini variants), and Pielou’s eveness (Legendre and Legendre 1998).
