Distribuição de indivíduos de três espécies arbóreas da caatinga provenientes da regeneração natural.

Abstract

Study on Caatinga natural regeneration allows to preview forest behavior and future development, as it furnishes a list of species, and the quantity and distribution of each species that compose the forest community. The objective of the present study was to monitor Amburana cearensis, Myracrodruon urundeuva and Handroanthus impetiginosa individuals in a preserved forest remnant located at the Fazenda Tamanduá RPPN (Private Reserve of the Natural Patrimony), in Santa Terezinha (PB). Data on height, basal diameter and breast-high circumference were collected fortnightly in order to classify the plants of each species according to these parameters. Regeneration was monitored in a 30m radius around three isolated trees of each species. A total of 116 regenerating individuals observed around the isolated trees showed to be evenly distributed in the five height and diameter classes used in this study. This shows that the natural regeneration of the three tree species is satisfactory, probably due to no antropic pressure in the area.
