In jbcannon/landecoutils: Utility Functions for the Landscape Ecology Lab

Calculate the single-trunk DBH equivalent of a multi-trunked stem.

Description

This function calculates the single-trunk equivalent DBH of a multi-trunked stem by calculating the sum of the basal area of all stems, then calculuating the single-tree DBH that would produce the same basal area. Following the method of Steward and Salazar, 1992.

Usage

dbh_equiv(dbh, na.rm = TRUE)

Arguments

dbh	numeric - vector representing measure of mulit-trunked stem diameter at breast height
na.rm	boolean - should NAs be ignored.
