Guideline volume curves from diameter only by Laasasenaho 1982.

Description

"The accuracy of equations based on diameter at breast height alone is in any case poor, and the equations are material specific. In some inventory tasks guideline volume curves, based on diameter only, are required. The following equations....can be used for this type of task."

Usage

Laasasenaho_1982_tree_volume_Finland(diameter_cm, species = "Picea abies")

Arguments

diameter_cm

Diameter at breast height 1.3 m in cm.

Details

Pine relative SE = 17.2 percent.

Spruce relative SE = 18.7 percent.

Birch relative SE = 18.8 percent.
