    About the Models

    These models were developed for use by forestry researchers and practitioners interested in modeling growth and yield/carbon balance for the three most important southern pine species: loblolly pine, slash pine, and longleaf pine. Model development was funded by several agencies including the Department of Defense Strategic Environmental Research and Development program; the USDA-NIFA PINEMAP project; and the UF/IFAS Dean for Research Office through the University of Florida (UF) Carbon Resources Science Center.

      model for longleaf pine plantation

      Example of Model Output: Left: Average C stock (Mg C per hectare) for a 500 years simulation for a longleaf stand with Rotation length=80 years, SI=80 ft, PD=600 trees per acre, thinned at BA=75 ft2 per acre when BA reached 110 ft2 per acre. Right: Time series of In Situ (upper panel) and Ex Situ (lower panel) C Pools.

      This model allows the user to simulate stand dynamics of planted loblolly, longleaf and slash pine forests under different management scenarios. This research was supported by the U.S. Department of Agriculture Forest Service Grant and the Florida Department of Agriculture and Consumer Services, Florida Forest Service.
