LANDIS is a forest landscape model designed to simulate forest growth, competition, seed dispersal succession, and disturbances (including fire, wind, harvesting, insects, global change), across large (>1 million ha) landscapes. LANDIS represents landscapes as a grid of cells and tracks age cohorts of each species (presence/absence or biomass) rather than individual trees. LANDIS simulates distinct ecological processes, allowing complex interactions to play out as emergent properties of the simulation.
Background
LANDIS was developed beginning in the late 1990s with partial funding from the Northern Research Station, Rhinelander, Wisconsin. Development was a joint effort among Dr. David Mladenoff (University of Wisconsin), Dr. Hong He (University of Missouri), Dr. Robert Scheller (Portland State University), Dr. Eric Gustafson (NRS) and Dr. Brian Sturtevant (NRS). The current version (LANDIS-II) was designed using modern software engineering techniques and allows users to select from an extensive library of process-based modules (extensions) to customize the model for specific applications.
