This dataset contains individual tree-level structural data collected during the forest inventory. It records taxonomic species classifications, health status, stem dimensions (DBH, height, crown features), bark thickness across cardinal directions, specific damage codes, and local spatial coordinates (Easting, Northing, Distance, Elevation) for canopy-forming and sub-canopy individuals.

CondClass values like 9), variables such as Ht_m, CBH_m, and bark configurations are left blank. This reflects standard protocol when structural deterioration prevents accurate measurement.
