Barro Colorado Island Tree Counts
Description
This dataset, lifted from vegan, contains tree counts in 1-hectare plots in Barro Colorado Island, Panama.
Usage
data(BCI.count)
Format
A data frame with 50 plots (rows) of 1 hectare with counts of trees on each
plot with total of 225 species (columns). Full Latin names are used
for tree species.
Details
Data give the numbers of trees at least 10 cm in
diameter at breast height (1.3 m above the ground) in each one hectare
square of forest. Within each one hectare square, all individuals of
all species were tallied and are recorded in this table.
The data frame contains only the Barro Colorado Island subset of the
original data.
The quadrats are located in a regular grid. See examples for the
coordinates.
