Structure of the woody component of an Atlantic forest Fragment, Moreno - PE

Abstract

The aim of this study was to evaluate the phytosociological structure of an adult woody component in an Atlantic Forest fragment known as Mata da Onça, Municipality of Moreno - PE. Fifteen plots of 10 x 25 m were established, in three rows of five plots 25 m apart, while the rows were 50 m apart. The adult woody individuals with CBH (circumference at 1.30 m above ground level) ≥ 15 cm were identified to the species level, and the diameter and height were measured. 444 individuals belonging to 76 species were sampled, with an estimated density of 1,184 ind.ha -1 and estimated absolute dominance of 28 m2.ha -1. The most representative species were Parkia pendula,Tapirira guianensis, Albizia saman, Schefflera morototoni, Miconia prasina, Inga thibaudiana, Eriotheca crenulaticalyx, Cupania racemosa and Cecropia pachystachya. The diversity index was 3.61 nats.ind -1 with an evenness of 0.87. Therefore, the results observed are similar or high compared to others Atlantic Forest fragments within the region despite its anthropized situation, which emphasizes the importance of conserving this area.
