Tree-list data from a forest sampling work

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.

Usage

Format

Contains tree-level variables, as follows:

species

Species common name as follows: Olivillo=Aextocicon puncatatum, Tepa=Laureliopsis philippiana, Lingue=Persea lingue, Coigue=Nothofagus dombeyi, Roble=Nothofagus obliqua, Other=Other
