3. R functions for computing tree stem volumes. Run the following script in R to load functions for computing volumes for a tree stem, or any part of a tree stem (note if you copy the text to R, the quotes may not copy correctly):
Or download the script here (right-click, save as…).
The computations employ volume integrals of tree stem taper, which makes it possible to easily compute the volume for any part of a tree stem, if tree diameter and intact height are known. Functions are included for Abies balsamea and Picea mariana (Quebec), and Pinus sylvestris, Picea abies, and Betula spp. (Finland).
