quadrat3_rect.df

A dataset containing tree measurements from 25 rectangular quadrats
(20 × 10 m each) sampled in a seasonal semideciduous forest fragment
in the State of Sao Paulo, Brazil. The dataset includes total height and
commercial bole height of trees, along with the spatial coordinates of the
lower-left corner of each quadrat. It is organized to demonstrate the use
of the function <code>BAplot()</code> with rectangular quadrats.

datasets

Provides functions and example datasets for phytosociological
analysis, forest inventory, biomass and carbon estimation, and visualization
of vegetation data. Includes functions to compute structural parameters
[phytoparam(), summary.param(), stats()], estimate above-ground biomass
and carbon [AGB()], stratify wood volume by diameter at breast height (DBH)
classes [stratvol()], generate collector and rarefaction curves [collector.curve(),
rarefaction()], and visualize basal areas on quadrat maps [BAplot(), including
rectangular plots and individual coordinates]. Several example datasets are provided
to demonstrate the functionality of these tools. For more details see FAO
