Description
Find approximately reasonable default values for tree size parameters
Usage
1
solve_tree(dbh = NA, height = NA, crown_radius = NA, region = "nw")
Arguments
dbh
Diameter at breast height, in meters.
height
Bole height, in meters.
crown_radius
Crown radius, in meters.
region
Currently ignored. Exists to allow future expansion of
parameters, to let functions more realistically scale trees for a given
region.
Value
A named list with default values for dbh, height, and crown_radius.
