Amazon, Floristic, Ecological groupsAbstract
This work was carried out in a stretch of Dense Rain Forest in the lowland county of Carauari, Amazonas, aiming to estimate the species composition of tree layer and classify the species in their ecological groups in order to obtain information about the current situation of the forest fragment, to be the basis for strategies for conservation and preservation as well as the basis for formulating research aimed at the dissemination of knowledge and its application to sustainable production. The forest inventory was conducted in an area of 275 ha, crossed by three transects (822 m, 1,265 m and 2,349 m), totaling 4.436 m. Plots were installed in 20 m x 25 m, 50 m equidistant, merged to the right and left of the line transect, totaling 66 sampling units. All tree individuals trees that had a circumference of 1,30 m above the ground (CAP) ≥ 25 cm were identified and measured. There were 3,050 individuals distributed in 133 species, 93 genera and 49 families. It was observed that the species of early succession (pioneer + early secondary) were more numerous, showing characteristics of a forest in early successional stage.
