A major conclusion is that light detection and ranging (LiDAR)-based sampling combined with an allometric model of tree biomass that uses height measurements is significantly better than simply using the Intergovernmental Panel on Climate Change Tier 1 prescribed forest carbon values (2) for a given area [395 teragrams (Tg) or 1012 grams carbon (C) vs. 587 Tg C].
