    Abstract: The aim of this paper was to analyze tree structure and value a secondary low floodplain forest. The study area is located at EMAPA forest lands, in the county of Afuá, in the state of Pará. The inventoried area presents 12.5 ha, where all the tree specimens with DBH 〉 or = 15.0 cm were measured. A total of 73 species were identified, corresponding to 357.7 individuals/ha and a 23.4 m²/ha basal area, the most important being Virola surinamensis, Symphonia globulifera, Eschweilera coriacea, Pentaclethra macroloba and Astrocaryum murumuru. Among the categories, the non-commercial species showed the highest number of marketable boles (24.3/ha), followed by the commercial (16.2/ha) and potential ones (12.9 boles/ha). The boles and the heartpalms provided a potential income of US$ 501.70/ha and US$ 68.50/ha, respectively.

    Manejo sustentado para floresta de várzea na amazônia oriental

    Abstract: The aim of this study was to define tree cut options in a sustainable basis for floodplain forests in the Amazonian Estuary. Data were obtained from the survey carried out in the forest lands of Wood Exports of Pará Ltda. - EMAPA Enterprise, located in Afuá County, North of Pará State. Sampling was performed in 29 plots of 5.000 m². There were surveyed all trees, including palm trees with diameter at 1.30m above ground level (dbh) 〉 45 cm. Trade species with possibility to be harvested for presenting best phytossociological and qualitative indexes were: Virola surinamensis, Carapa guianensis and Hymenaea oblongifolia; among potential species Terminalia dichotoma was chosen; while in the non-trade species group, Eschweilera coriacea, Swartizia racemosa and Licania macrophylla were selected. Results showed that the forest management can be done by adopting a harvesting plan with a De Liocourt value 50% higher than the original (q = 2,61) one and removal of 30% of basal area, which corresponds to a potential income of US$ 3.945,40/ha.

    Estrutura e potencial futuro de utilização da regeneração natural de floresta de várzea alta no município de Afuá, estado do Pará.

    Abstract: O presente estudo teve como objetivo analisar a estrutura e indicar as probabilidade de utilização futura da regeneração natural de uma floresta não-explorada de várzea alta localizada no município de Afuá (0° 09' 24" S e 50° 23' 12" W), ao norte do estado do Pará. Foram amostradas 29 subparcelas de 100 m2 nas quais se mediu a altura (h) de árvores e palmeiras com h 〉 0,30 m até o diâmetro a 1,30 m do nível do solo (DAP) 〈  15 cm,  e o diâmetro das árvores compreendidas entre h  〉 3,0 m até DAP 〈  15 cm.  A densidade total foi 30.969 indivíduos/ha, pertencentes a setenta espécies, 57 gêneros e 25 famílias botânicas, com índice de diversidade de Shannon (H') de 2,68. As espécies mais importantes foram: Virola surinamensis, Euterpe oleracea, Astrocaryum murumuru, Geonoma laxiflora e Guarea guidonia. Muitas espécies são utilizadas como alimento pela fauna local, além de servirem como fonte de madeira e/ou, de produtos florestais não-madeireiros; algumas destas funcionam como complementação à dieta alimentar dos ribeirinhos, tais como: Eschweilera coriacea, Gustavia augusta, Inga Alba, Nectandra cf. risi e Protium spruceanum.

    Composição florística e estrutura da regeneração natural de floresta secundária de várzea baixa no estuário amazônico

    Abstract: This paper aimed to analyze the natural regeneration structure of an exploited low floodplain forest located at EMAPA forestlands, Afuá County, in northern Pará. Sampling was accomplished in 25 sub-plots of 100 m². In each sub-plot of 100m², all individuals with height (h) 〈 FONT FACE=Symbol 〉 ³ 〈 /FONT 〉 0.30 m and diameter at 1,30m above ground level (DBH) 〈 FONT FACE=Symbol 〉 £ 〈 /FONT 〉 15.0 cm were surveyed and were botanically identified, as well as all the plants with (h) 〈 FONT FACE=Symbol 〉 ³ 〈 /FONT 〉 3.0 m and diameter at 1.30 m above ground level (DBH) 〈 15.0 cm. A total of 13.380 individuals/ha distributed in 63 species, 51 genera and 23 botanical families were sampled. The most important species of the phytocenosis were: Euterpe oleracea, Astrocaryum murumuru, Crudia bracteata, Gustavia augusta and Inga edulis. Over 60% of the species studied in the area showed a clustering distribution pattern and a Shannon-Weaver index (H´) of 3.05.
