This file provides data describing the density and configuration of sample tree neighborhoods for calculation of competition indices. The distance to and diameter at breast height (DBH; 1.3 meters above root crown) of all neighboring trees within a 15 m radius of the sample or target tree were measured. A total of 10 sample trees had empty neighborhoods (no neighbor trees within 15 meters). File headings include:
Sample tree ID: Identification code for the sample or target tree
Sample tree species: Species of sample tree
Neighbor tree species: Species of neighbor tree
Neighbor tree DBH: Diameter at breast height of neighbor tree in centimeters
Distance to neighbor tree: Distance from sample to neighbor tree in meter
