FORECAST is an ecosystem-based, stand-level,
forest growth simulator. The model was designed to accommodate a
wide variety of harvesting and silvicultural systems in order to
compare and contrast their effect upon forest productivity, stand
dynamics, and various biophysical indicators of non-timber values.
The model uses a hybrid approach whereby local growth and yield
data are combined with other data to derive estimates of the rates
of key ecosystem processes related to the productivity and resource
requirements of selected species. FORECAST uses relatively simple
measures of decomposition, nutrient cycling, light competition,
and other ecosystem properties to simulate forest growth and ecosystem
dynamics under changing management conditions. Growth occurs in annual time
steps. Depending upon the species, plant populations within the
model can be initiated from seed and/or vegetatively, and stand
development can occur with or without competition from non-target
tree species and understory populations.
The user interface of FORECAST consisting
of soil, tree, plant, and moss setup information, as well as management
and output options.
