A checklist of the basics:
Species distribution models (SDMs) combine observations of species occurrence or abundance with information about environmental variables to gain ecological insights and to predict species’ distributions across landscapes. SDM outputs usually include:
(i) a document describing the data and statistical modelling process used to generate the SDMs,
(ii) a summary of the resulting numerical or statistical model, and
(iii) a map of the probability of a species’ occurrence over a region of interest (or the relative likelihood of occurrence in different parts of the region in the case of models that use only presence records).
