eq_biomass_cudjoe_2024: Biomass equations for 2 species in Castille and León (Spain)

Description

Allometric equations adjusted for Quercus petraea, and Pinus sylvestris in Castille and León (Spain)

Usage

eq_biomass_cudjoe_2024(species, component = "AGB", return_rmse = FALSE)

Value

A S7 list of parameters

Arguments

species

A character string specifying the scientific name of the tree species. It can be a column name if all the species are included in this model. See Details for available species.

component

A character string specifying the tree component for biomass calculation (e.g., "stem", "branches"). See Details.

return_rmse

A logical value. If TRUE, the function returns the root mean squared error (RMSE) of the selected model instead of the biomass value.

Details

There are three species options in this model:

• Quercus petraea

• Pinus sylvestris

• Mixed: stands with Quercus petraea and Pinus sylvestris

The tree components include some AGB components:

• leaves: only for P. sylvestris

• stem: for all species

• medium branches and small brances: for all species

• thick branches: for all species

• AGB: total biomass, results of summing the previous components
