In ryanmismith/inventoryfunctions: Forestry Inventory Functions

Kozak Taper Equation

Description

This function allows you to calculate the diameter at any point on tree for common tree species found in the northeastern and acadian forests. All measurements must be entered as metric. Function requires you to gives the specified height on tree for which you want diameter calculated.

Usage

KozakTaper(Bark, SPP, DHT, DBH, HT, Planted = FALSE)

Arguments

Bark	specify if you want measurement inside or outside bark: 'ob' = outside, 'ib' = inside
SPP	Species: use FVS species codes: example 'RO' - Red Oak, 'WS' = White Spruce
DHT	Diameter at Height in cm where diameter measurment is desired
DBH	Diameter Breast Height in cm
HT	Tree Height in meters
Planted	specify if the tree is planted, specify as TRUE or FALSE. Defaults to FALSE.
