| Popis: | The aim of this paper was to analyze the structure and describe the future potential of use of the natural regeneration in an non-exploited upland floodplain forest located at EMAPA forestlands, Afuá County (0° 09 24 S and 50° 23 12 W), North of Pará State. The sample consisted of 29 sub-plots of 100 m2. In each sub-plot, all trees and palms with height (h) ³ 0.30 m and diameter at 1.30 m above ground level (DBH) < 15 cm were identified and measured. All trees with h ³ 3.0 m and DBH < 15.0 cm were measured too. The total density was 30,969 individuals/ha distributed into 70 species, 57 genera and 25 botanical families, with a Shannon Index (H) of 2.68. The most important species were: Virola surinamensis, Euterpe oleracea, Astrocaryum murumuru, Geonoma laxiflora e Guarea guidonia. There are many species used for the local fauna as feeding, and many that also provide timber and non-timber forest products; some of them function as an addition to the diet of the riverine people, such as: Eschweilera coriacea, Gustavia augusta, Inga Alba, Nectandra cf. risi e Protium spruceanum. |
