How the data was generated

Species distribution maps and threat vulnerability maps are developed through collecting species occurrence records, identifying environmental predictor variables, modelling species distributions for current and future climate scenarios, evaluating models for their stability, and lastly, validating resulting distribution maps by species experts and through literature.

Methods vary slightly between different geographies. Methods are described in detail in these publications:
