Species distribution models (or SDM's) are used to explore how the occurrence of a species is related to the environment, and how a species might respond to changes in its environment. This can help find new locations where a rare species might be found, or understand the potential threats to a species due to urban encroachment, climate change, or other causes.For example, here is a model of the distribution of the Sydney Red Gum (Angophora costata) in the Sydney basin, as a function of climate variables and fire history. The model was constructed using a Poisson...more
