Description of a forest stand.

Description

exampleforest is an example of forest stand description, whereas exampleforest2 is an alternative forest description where leaf area index and crown ratio are supplied instead of structural (density, DBH and cover) parameters.

Format

An object of class forest contains the description of the woody (tree or shrub) cohorts and herb layer of a forest patch. It has the following structure (see details):

Details

The structure presented above for forest objects corresponds to the required data elements. A forest object can contain additional information when this is available. Data frames treeData and shrubData can contain additional columns:

Similarly, one can define forest list elements herbLAI, herbFoliarBiomass or herbFuelLoading. All these values are used to override allometry-based estimates of those variables when initializing inputs for functions spwb or spwb_day. Note that leaf area index, foliar biomass and fuel loading are related entities, and they are treated as such in medfate. Therefore, users are expected to supply one or the other, and not all of them at the same time.
