Description

Tree-level variables measured within three sample plots in a forest sampling effort. This sort of work is commonly referred as a forest inventory. Notice that plots might have different areas. The sampling was carried out in a secondary forest of Nothofagus obliqua in the Rucamanque experimental station, near the city of Temuco, in southern Chile.
