Description:

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. All trees 6 cm DBH and greater and considered “in” were identified by species and DBH measured. Heights were imputed using a Height – Diameter curve and the heights measured on the big BAF plots. The big BAF plots had the same plot design as the horizontal point samples and a 27-M BAF angle gauge was used to select trees for height measurement. All four plot types were center of the 100 m grid intersections. Grids do not align with EFI cells because the 100 m grid was established independently and prior to the EFI cells. The X – Y variables are the locations (in m) of the cell center (for Femel_EFI_GTV) and the plot centers (for Noonan_FemelPlot_GTV) with {0,0} being the SW corner of the study area.
