Abstract:
TROLL is an individual-based forest growth model, designed to
run for large plots of dense natural forests, with special emphasis
on neotropical rainforests. The space resolution is 1 m, and
the competition for light is spatially-explicit, occuring
within voxels of size 1m x 1m x 0.5m. Growth and mortality modules
are similar to those of a classic gap model. The seed dispersal
module is spatially explicit (eg. each produced seed is dispersed
at a distance drawn from a dispersal kernel). Plot size over 1 square
kilometers have been simulated using a parallel computer (Cray T3E)
and real-time message-passing across processors (MPI). Now, TROLL
is running on the Compaq SC232 of the Commissariat a l'Energie
Atomique (Grenoble, France).
