Fire Succession Model (FIRESUM) is a deterministic ecosystem process model that
simulates long-term stand dynamics of forests in the Northern Rocky Mountains.
The model simulates tree regeneration, growth and mortality given stochastic
fire events. In the model, individual trees are grown deterministically using
an annual time step. Tree growth is affected by light, water and nutrients.
Fuel loadings are calculated annually and fire is simulated by reducing litter,
duff, and down woody fuels. The model simulates forest stand dynamics.
The model requires species parameters as input as well as site parameters, such
as weather, elevation, and soil characteristics. Output includes the average
basal area for each tree species simulated, fuel values of forest components
and fire behavior statistics.

VI. Additional remarks
In a climate scenario involving dryer climates in the Rocky Mountains, this model could be useful in examining the effects of increased fire due tothe drier climate.
