Tree size, competition, and diameter growth increment of
Metrosideros polymorpha trees collected in the Kilauea Volcano, Hawaii.
Data containing 64 observations at the current annual growth
rate (defined as dbh increment within one calendar year) of each tree.
Measurements were made from 1986 to 1988.
data(hawaii)The dataframe has the following columns:
Tree number identification. The first letter of the ID represents a cohort. Six cohorts representing a chronosequence were sampled.
Diameter at breast height, in cm.
Total height, in m.
Crown outline area, in square meters.
Competition index (Basal area of nearest neighbor divided by square of distance to nearest neighbor plus basal area of second nearest neighbor divided by square of distance to second nearest neighbor).
Current annual stem diameter increment during 1986, in mm.
Current annual stem diameter increment during 1987, in mm.
Current annual stem diameter increment during 1988, in mm.
