The Across Trophic Level System Simulation (ATLSS) is a suite of computer models used for restoration assessments. Researchers compiled a baseline of information and methods for the development of ATLSS models. Investigative reports included studies of spatially explicit trophic interactions, the interactions of fire and soil nutrients, and vegetative succession with seasonal hydroperiods. Standard methods included using 1) a landscape structure model that features a map layer of higher resolution topography than that of the South Florida Water Management Model (the primary interagency simulation model of south Florida hydrology used at that time.)in south Florida known as the, and 2) a layer of vegetative communities defined by the Florida Gap Analysis Project (FGAP). Completed models included spatially explicit species index models of the Cape Sable seaside sparrow, snail kite, short- and long-legged wading birds, white-tailed deer, fish, and alligators, and PANTRACK, which analyzes Florida panther radio-telemetry data.
