ABSTRACT
The dynamics of
forest growth are related to the succession stage, the quality of the
environment and the degree of anthropism. The growth of a forest is given by
the activity of live trees, mortality, and trees that are cut or recruited
during the growing period. A way of representing the growth dynamics of a
forest is by the Transition Matrix, with the divisibility of the population in
states, with probabilities of movement from one state to another, over time.
Forest dynamics studies are carried out by means of a continuous forest
inventory, allowing the calculation of gains and losses in basal area,
mortality rates and ingrowth. In this study, the measurements were performed
with a 5-year interval, on 27 plots distributed in 12 sites. The methodology
correlated parameters of the forest dynamics with canopy, soil, relief and
hydrographic parameters. An indicator of forest growth dynamics was proposed
and it was tested. It was confirmed that the density factor interferes in
growth dynamics of the forest.
