The first operational model produced with partial support from the Grassland Biome study was PRONG, a system-level model for the shortgrass prairie developed as a training exercise by a team including several members from the Biome study. This simulation model contained abiotic, autotrophic, and heterotrophic components but it was greatly simplified in detail both in number of state variables and mechanism in the process functions.
