The forest stand growth simulator FORET was developed by adapting the northeastern forest growth model JABOWA for modeling the diverse forests of the southern United States. Several major modifications were made:

  1. Installation of additional subroutines: SPROUT (simulates stump and root sprouting) was installed, because vegetative reproduction can be the dominant mode of reproduction, particulary for hardwood species. GAUSS (a normal random number generator) returns a value of DEGD (growing degree days).
  2. Removal of subroutines SITE (produced indices of the quality of the site for growing trees) and CUT (simulation of tree logging).
  3. Other modifications: increase in the number of tree species from 13 to 33 and change from 10 m x 10 m square plot to circular plot with size of 1/12 ha.
