Series: Boletim de Pesquisa - EMBRAPA. Centro de Pesquisa Agropecuaria do Tropico Umido (Brasil).Publisher: Belem, PA (Brasil) 1981Description: 34 p.Subject(s): CRECIMIENTO | DIAMETRO | VOLUMEN | DISTRIBUCION DE LA POBLACION | BOSQUE TROPICAL HUMEDO | AMAZONIA | BRASIL | GROWTH | DIAMETER | VOLUME | POPULATION DISTRIBUTION | TROPICAL RAIN FORESTS | AMAZONIA | BRAZIL | CROISSANCE | DIAMETRE | VOLUME | DISTRIBUTION DES POPULATIONS | FORET TROPICALE HUMIDE | AMAZONIE | BRESIL In: Summary: This work studies, in a area of a tropical rain forest, the frequency of trees, the volume and the composition of the forest at various diameter classes. It will be very important for studying and planning the management to the high forest of the plateau, where does not occur the "babacu" palm, in the region of Tapajos river. Twenty-two families and about 140 species were examined. All of the trees, with diameter of 15 cm and above, were measured an distributed in 15 diameter classes. Some species occurred up to 10 classes, other occurred only at one class. The conclusions are: there is variation of frequency in different species; the species of long life are very frequent at all of the classes; the volume is connected with the frequency of tree for species; and the general form of distribution of the diameter classes in the Amazon rain forest, probably presents a curve line nearly balanced with higher frequency in the larger classes.

This work studies, in a area of a tropical rain forest, the frequency of trees, the volume and the composition of the forest at various diameter classes. It will be very important for studying and planning the management to the high forest of the plateau, where does not occur the "babacu" palm, in the region of Tapajos river. Twenty-two families and about 140 species were examined. All of the trees, with diameter of 15 cm and above, were measured an distributed in 15 diameter classes. Some species occurred up to 10 classes, other occurred only at one class.
