Impact model: ED2

The Ecosystem Demography model version 2.1 is a terrestrial biosphere model that couples plant community dynamics to biogeochemical models of associated soil fluxes of carbon, water, and nitrogen. ED2 is explicitly designed to scale from the individual level to the regional level and to account for community-level processes such as disturbance and resource competition in a manner analogous to forest gap models.
