The objectives of the modelling efforts in the US/IBP Grassland
Biome were to stimulate the precise formulation of ideas about the
behavior of the system, help direct the research effort through the
identification of critical areas for study, and produce a tool for
investigating the consequences of management alternatives.
The objectives of the model were to simulate biomass dynamics in
a variety of grassland types and the response of the system to
irrigation, fertilization, and cattle grazing. The model was
constructed over a period of several years by a team of
investigators, each of whom assumed responsibility for one of the
component submodels: i.e., abiotic, producers, mammals, grasshoppers,
decomposere, nitrogen, and phosphorus. The primary information source
used in developing this model was the US/IBP Grassland Biome intensive
study site, Pawnee.
