Scripts show the data preparations, modelling area preparation and SDM methods (from Breinman et al). They require downloading external data, eg from range maps from IUCN red list (permission required) and predictor layers. They are intended to show analysis steps.

The extinction risk model follows Thompson et al (2017). Scripts here follow those in supp material of the paper. The first script prepares eBird absence data for estimating study area surveyed in passive surveys.
