The forest stand growth simulator FORET was developed by adapting the
northeastern forest growth model
for modeling the diverse forests of the southern United States. Several major
modifications were made:
- 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).
- Removal of subroutines SITE (produced indices of the quality of the site
for growing trees) and CUT (simulation of tree logging).
- 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.
