Projeção diamétrica por razão de movimentação em um fragmento de floresta ombrófila mista no sul do paraná

Abstract

The aim of this research was to simulate the growth in number of trees and basal area of a Mixed Ombrophilous Forest fragment, in level of forest, botanical families and species with the greater importance value. The data are from a continuous inventory in three sample plots of 1 ha each, and one of 0.5 ha, adding up 3.5 ha of sampled area, in São João do Triunfo, Paraná. All trees with diameter at breast height equal or greater than 10.0 cm were identified, measured and, during remeasurements, all recruited and dead trees were counted until the year 2011. The projections with movement ratio model were performed to the individual trees grouped in classes' interval of 10 cm diameter for the prognosis of the years 2013, 2015, 2017 and 2019. The forest as a whole will grow 5,7 m 2.ha -1 in basal area, but not in number of trees, confirming maturation of this fragment.
