The basal area of stands

Description

The basal area is the cross sectional area of the bole or stem of a tree at breast height.

Usage

basal(dbh, area, k = 100)

Arguments

dbh	numeric, vector of diameter.
area	numeric, area of a plot (see details for unit).
k	numeric, used to convert diameter unit. Default is 100 (see details)

Details

If area is expressed in ha and dbh expressed in cm, the basal area unit is cm\u00b2/ha when k = 1. In order to convert centimeter (cm) to meter (m) for dbh, set k = 100. Because 1m = 100 cm. Then, basal area unit will be m\u00b2/ha.

If dbh is in meter (m), and area in in hectare (ha), setting k = 1 returns basal area in m\u00b2/ha.

If dbh is in feet, and area in acre, setting k = 1 returns basal area in ft\u00b2/ac.

If dbh is in inch, and area in acre, setting k = 12 returns basal area in feet\u00b2/acres (ft\u00b2/ac).

Value

A vector of basal area of stands.
