- Abstract
The objective of this study was to analyze the structure and income expectation generated by tree species, considering timber and non-timber forest products in the municipalities of Santarém and Placas, Pará (PA). The study area was in the São Mateus community, the Settlement Project of INCRA Moju I and II, municipality of Placas, PA. The study area was in the São Mateus community, the Settlement Project of INCRA Moju I and II, municipality of Placas, PA. A forest inventory was used with systematic sampling of 11 sample units of fixed area of 50 m x 200 m, totaling 11 ha. All individuals with DBH ≥ 10 cm were measured, considering different size classes (CT) and sub-samples. A total of 903 individuals with DBH ≥ 10 cm (501.6 tree-ha-1) were distributed in 48 families and 143 botanical species. The botanical families with the highest species richness were Fabaceae (36), Sapotaceae (13), Lecythidaceae (10), Malvaceae (7), Moraceae (7), Annonaceae (5), Burseraceae (5) and Lauraceae . The families represent 61.5% of the number of species, confirming that few botanical families represent a large number of species in DenseOmbrophylousForest. The Jentsch mixing coefficient (QM) presented, on average, 6.31 individuals per species; the basal area was 28.77 m².ha-1; the Shannon Weaver index (H ') 4.28; the Maximum diversity (H'max) 4.96 and the Pielou Equability (J) 0.86. The unmanaged forest presented stock of species with potential lumber and not timber. Logging activities and NTFPs can generate profits per hectare above the minimum wage and help supplement the incomes of settled families.
