vol.w = TRUE, vol.wo = TRUE)

Arguments

dbh.mm	tree dbh in mm
height.dm	tree height in dm
tree.sp	tree species following the same codification as the Norwegian NFI
kom	municipality code
vol.reduksjon	volume reduction in 100
vol.w	TRUE/FALSE if volume with bark needs to be calculated
vol.wo	TRUE/FALSE if volume without bark needs to be calculated

Value

It returns a list with up to two elements:

vol.w.tr.m3	volume with bark per tree in m3
vol.wo.tr.m3	volume without bark per tree in m3

Examples

volume.norway(dbh.mm = c(50,70), height.dm = c(17,20), tree.sp = c(1, 10), kom = c(623, 623))
