Resumo: | Purus National Forest (PNF), located in the municipality of Pauiní, Amazonas state, Brazil, has a high conservation status and a population of about one thousand inhabitants. However, the scarcity of environmental studies in a suitable scale for the PNF management planning demands studies that quantify and qualify the stock of resources, that identify the community demand and set sustainable forest production techniques. Thus, the objective of the present work was to analyze the floristic composition, forest structure and the forest management potential of part of a "terra firme" dense ombrophylous forest located in the Forest Management Unit (UMF-1) of Céu do Mapiá village, the largest populational nucleus of PNF. To do so, a forest inventory was made, sampling in a block of 12 parcels of 50x50m, and all trees with DBH ≥ 10 cm were measured. The floristic composition was carried out and the Shannon-Wiener diversity index and Pielou equability index were used to assess the biodiversity and the uniformity of the community. The structural forest analysis was based on the absolute and relative values of density, dominance, frequency, importance value and diameter distribution of the basal areas and volumetric estimates of the population. A total of 1,764 individuals, pertaining to 35 botanic families, 91 genera and 163 possible specimens were registered, emphasizing that less than 40% (65) were identified at the species level. The UMF-1 is characterized by the high floristic diversity (H'= 4.10), few dominant species (J = 0.81) and many species with low abundance. Out of the commercial species used by the community, three are among the ten species with the greatest importance value, a total of 26 possible commercial species of sustainable exploitation. |

No entanto, a carência de estudos ambientais em escala adequada para o planejamento da gestão da FLONA torna imprescindíveis levantamentos que quantifiquem e qualifiquem o estoque de recursos, identifiquem a demanda comunitária e fundamentem técnicas de produção florestal sustentável. Nesse sentido, o objetivo do presente trabalho foi analisar a composição florística, a estrutura florestal e o potencial de manejo florestal de um trecho de floresta ombrófila densa de terra firme, localizado na Unidade de Manejo Florestal-1 (UMF-1) da Vila Céu do Mapiá, maior núcleo populacional da FLONA. Para tanto, foi realizado um inventário florestal por amostragem aleatória de 12 parcelas de 50x50m, sendo mensurados todos os indivíduos com DAP ≥ 10 cm. Foi realizada a análise da composição florística, bem como utilizados os índices de diversidade Shannon-Wienere de equabilidade de Pielou, para avaliar a diversidade e uniformidade da comunidade. A análise da estrutura da floresta foi baseada nos valores absolutos e relativos de densidade, dominância, frequência, valor de importância e distribuição diamétrica, da área basal e estimativas volumétricas do povoamento. Foram registrados 1.764 indivíduos, pertencentes a 35 famílias botânicas, 91 gêneros, e 163 possíveis espécimes, ressaltando que menos de 40% (65) foram identificadas em nível de espécie. A UMF1 caracteriza-se pela alta diversidade florística acumulada da comunidade arbórea amostral (H'= 4,10), poucas espécies dominantes (J = 0,81) e muitas espécies de baixa abundância. Das espécies comerciais utilizadas na comunidade, três figuram entre as dez espécies com maior valor de importância, em um total de 26 espécies comerciais possíveis de exploração sustentável.Universidade Federal de Santa Maria2020-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1518910.5902/1980509815189Ciência Florestal; Vol. 30 No. 4 (2020); 944-957Ciência Florestal; v. 30 n. 4 (2020); 944-9571980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/15189/pdfCopyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessBrandão, Pedro ChristoSouza, Agostinho LopesQuinet, AlexandreMendonça, Bruno Araujo Furtado de2021-05-20T04:00:48Zoai:ojs.pkp.sfu.ca:article/15189Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:48Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
