Florística, classificação sucessional e síndromes de dispersão em um remanescente de Floresta Atlântica, Moreno-PE

Abstract

The objective of this study was to evaluate the floristic, the successional classification and the dispersion syndromes of the arboreal component in an Atlantic Forest remnant. The area is located in Engenho e DestilariaDourado in Moreno, Pernambuco, Brazil. Fifteen plots of 10 × 25 m for the adult component (CBH e" 15 cm) and 15subplots of 1 × 25 m for the regeneration (CBH ≤ 15 cm and H ≥ 1 m) were located. The sampled individuals were classified into family, genus and specie, and the species classified for the succecional group (pioneers, early secondary and late secondary) and the dispersion syndrome (anemocorous, autochorous and zoochorous). Four hundred and forty-four adult individuals and 407 regenerants, belonging to 31 families, 47 genera and76 species, were sampled. The families with the highest species richness were Melastomataceae and Myrtaceae. This fragment is in early succession, since 82% of the species are pioneers or early secondary. The dispersion predominant was the zoochorous. The knowledge of the species presents in these areas, as well as the succession stage and the dispersion syndrome, is of utmost importance in the development of conservation and restoration intervention of these areas in the Atlantic Forest.
