Timber volume
Estimates of stem wood volume over and under bark, bark volume, and standard National Forest Inventory tariff models for both individual trees and per-hectare aggregates.
Plot-level variables
-
Volume_over_bark(VOL) —decimal•m3/ha•output: Vob•multi-species: sp1, sp2, sp3Wood volume over bark.
Simulation breakdown: This variable is automatically expanded for each target stand species (
Volume_over_bark_SP1,Volume_over_bark_SP2,Volume_over_bark_SP3). -
Volume_under_bark(BOLE_VOL) —decimal•m3/ha•output: Vub•multi-species: sp1, sp2, sp3Wood volume under bark.
Simulation breakdown: This variable is automatically expanded for each target stand species (
Volume_under_bark_SP1,Volume_under_bark_SP2,Volume_under_bark_SP3). -
Bark_volume(BARK_VOL) —decimal•m3/ha•output: V_bark•multi-species: sp1, sp2, sp3Bark volume.
Simulation breakdown: This variable is automatically expanded for each target stand species (
Bark_volume_SP1,Bark_volume_SP2,Bark_volume_SP3). -
