This is the second release of a BII tutorial. The document gives an example of how to model and project the Biodiversity Intactness Index (BII) using a subset of the PREDICTS (Projecting Responses of Ecological Diversity in Changing Terrestrial Systems) database and highlights some of the advantages, extensions, assumptions and limitations of the approaches used.
This version uses a different compositional similarity measure than used previously, to account for changes in community structure as well as species identity.
