Acadian Forest Volume Estimates Derived from Airborne LiDAR, Big BAF Sample Plots, and Fixed Area Plots on the Noonan Research Forest

The data are located on a 100 m N-S/E-W grid on the 80-ha Femelschlag Research Site on the Noonan Research Forest in New Brunswick, Canada. “Femel_EFI_GTV” contains the gross total volume (GTV; m3ha-1) estimates derived from airborne LiDAR scanning as part of the government of New Brunswick’s Enhanced Forest Inventory program. “Noonan_FemelPlot_GTV” contains the GTV estimates using four different plot types: fixed area plots with all trees measured for height; fixed area plots with 3P subsampling of heights; horizontal point sampling with all trees measured; and big BAF sample plots.

The fixed area plots were circular with an 11.28 m radius and all tree 6cm DBH and greater were identified by species and measured for DBH and height. The 3P subsampling was simulated using a Height – Diameter curve as prediction and a target subsample size of 100 trees across the 83 plots. The horizontal point samples used a 2-M BAF angle gauge to select count trees for measurement.
