Resumo

O objetivo deste trabalho foi descrever a fisionomia e a estrutura de um fragmento de Floresta Ombrófila Densa localizado no município de Catende, Pernambuco. Foram mensuradas todas as árvores com de DAP (diâmetro a altura do peito) ≥ 4,77 cm em quarenta parcelas (10 x 25 m), instaladas sistematicamente em cinco transectos. Observou-se 1.049 indivíduos, distribuídos em 91 espécies, 64 gêneros e 37 famílias botânicas. Mimosaceae e Lauraceae foram as famílias com maior número de espécies enquanto que Anacardiaceae e Moraceae tiveram o maior número de indivíduos. O índice do Shannon (H') foi de 3,83 nats/ind. A área basal total, a altura e o diâmetro (médio e máximo) foram 23,59 m2/ha, 13,57 m (±7,13), 45 m, 13,20 cm (±10,60) e 127,32 cm respectivamente. As dez espécies de maior valor de importância foram Tapirira guianensis check for this species in other resources Aubl., Dialium guianense check for this species in other resources (Aubl.) Sandwith, Helicostylis tomentosa check for this species in other resources (Poepp. & Endl.)

A distribuição diamétrica apresentou curva semelhante à forma de J-invertido, prevista para uma floresta ineqüiânea em estágio de sucessão secundária.

Abstract

This work aimed to describe physiognomy and structure of a Dense Ombrophyllous Forest fragment located in Catende, Pernambuco. All trees with DAP (breast height diameter) ≥ 4.77 cm were measured in 40 10 x 25 m plots, systematically installed in five transects. A total of 1049 individuals were observed, distributed in 91 species, 64 genera and 37 botanical families. Mimosaceae and Lauraceae were the families with higher species number, while Anacardiaceae and Moraceae had the highest individuals numbers. Shannon index (H') was 3.83 nats/ind. Total basal area, height and diameter (average and maximum) were 23.59 m2/ha, 13.57 m (± 7.13), 45 m, 13.20 cm (± 10.60) and 127.32 cm, respectively. The species with higher importance values were Tapirira guianensis check for this species in other resources Aubl., Dialium guianense check for this species in other resources (Aubl.) Sandwith, Helicostylis tomentosa check for this species in other resources (Poepp. & Endl.) Rusby, Thyrsodium spruceanum check for this species in other resources Benth., Plathymenia foliolosa check for this species in other resources Benth., Brosimum discolor check for this species in other resources Schott, Parkia pendula check for this species in other resources (Willd.) Benth. ex Walp., Schefflera morototoni check for this species in other resources (Aubl.) Maguire, Steyerm. & Frodin, Eschweilera ovata check for this species in other resources (Cambess.) Miers and Cecropia palmata check for this species in other resources Willd. Diametric distribution had an inverted-J-like curve, predicted for a forest unequal in ages in a secondary succession stage.
