Calculate tree height from DBH using allometric equations

Calculates tree height using asymptotic exponential growth curves: height (m) = 1.3 + a * (1 - exp(-b * DBH))

Usage

calc_height(dbh, species, allometric_params = get_default_allometric_params())

Arguments

dbh

Numeric vector. Tree diameter at breast height (cm)

species

Character vector. Species codes

allometric_params

List. Allometric parameters

Value

Numeric vector. Tree height (m)

Examples

# Single tree
calc_height(20, "PIED")
#> [1] 8.421164

# Multiple trees with different species
calc_height(c(10, 20, 30), c("PIED", "JUSO", "JUMO"))
#> [1]  5.648462  7.621206 11.083281

# Ponderosa pine
params <- get_ponderosa_allometric_params()
calc_height(40, "PIPO", params)
#> [1] 23.42422
