SAEM (Species, Area, Environment Model) is a step-wise regression model which predicts species or taxa for a specified area given the environmental characteristics. It can index biodiversity based on regional area using multiple regression to examine certain environmental components that effect species diversity or species complexes.

Model inputs include mean and annual precipitation, insulation, DEM, human population density, and total number of species (derived from species lists), standard surveys are used to obtain much of this information. Output data include the number of species expected in an area, and the location of species areas. SAEM can be used in conjunction with any statistical package.
