BAPH: Basal Area Per Hectare

In ryanmismith/inventoryfunctions: Forestry Inventory Functions

Basal Area Per Hectare

Description

This function calculates the Basal Area Per Hectare for each plot within your data set.

Usage

BAPH(Stand, Plot, BA, EXPF)

Arguments

Stand	The unique Stand ID for each Plot.
Plot	The unique Plot ID for each Plot.
BA	Diameter at breast height in cm.
EXPF	Expansion factor for each tree.

Details

This function requires that you calculate the Basal Area and the Expansion Factor for each tree in your inventory. See the EXP.F and BA functions if you need to do this.

Basal Area Per Hectare is a dependency for a number of other functions that may be useful in your analysis, so using a standard naming convention, while always good practice, will help when applying to additional functions. (ex: BAPH, BA.PH, BasalAreaPerHectare, BAPerHectare).

Value

Returns a vector of the length N with the basal area in sq meters per hectare for each plot.
