canFuel: Canopy Fuel Stratum Characteristics Calculator

Description

Canopy parameters estimated by Cruz, Alexander & Wakimoto (2003).

Usage

canFuel(ba, ht, tph, type)

Arguments

ba

a numeric vector of stand basal areas (m2/ha)

ht

a numeric vector of average stand tree heights (m)

tph

a numeric vector of stand densities (trees/ha)

type

a character vector of forest cover types, either: "df" for Douglas-fir (Pseudotsuga menziesii); "pp" for ponderosa pine (Pinus ponderosa); "lp" for lodgepole pine (Pinus contorta); "mc" for mixed conifer

Value

a data frame with canopy base height (m), canopy fuel load (kg/m2), and canopy bulk density (kg/m3)
