Resumo: | We determined the amounts of timber extracted, the damage caused by mining activity and the reduction of basal area obtained after the application of three systematic thinning intensities in an exploited in the Tapajós National Forest, municipality of Belterra, To area. The forest monitoring was accomplished through permanent plots measured before and after the operation and the application of thinning. The forestry extracted on average 11 árvores.he, 4,5m2.ha 61,0m3.ha1 basal area and volume, occurring large variation between treatments. For each commercial tree explored were lost on average 4.3 individuals with DBH 10cm and approximately 0,5m2 basal area severely affected by exploitation. The reduction in basal area, obtained with the logging and thinning performed by annealing and devitalization of known species without commercial value trees, was approximately 10% lower than planned in all treatments due to presence of large number of species with recesses in the shaft and exudation of latex or resin that hindered the implementation and application of annealing arboricida. |

O monitoramento da floresta foi realizado através de parcelas permanentes medidas antes e apos a exploração e a aplicação dos desbastes. A exploração florestal extraiu em media 11 árvores.he, 4,5m2.ha de área basal e 61,0m3.ha1 de volume, ocorrendo grande variação entre os tratamentos. Para cada arvore comercial explorada foram perdidos em media 4,3 indivíduos com DAP 10cm e, aproximadamente, 0,5m2 de área basal, afetados severamente pela exploração. A redução da área basal, obtida com a exploração de madeira e os desbastes realizados através do anelamento e desvitalização de árvores de espécies sem valor comercial conhecido, foi, aproximadamente,10% inferior ao planejado em todos os tratamentos devido a presença de grande número de espécies com reentrâncias no fuste e exudação de latex ou resina que dificultaram a execução do anelamento e a aplicação do arboricida.Universidade Federal Rural da Amazônia/UFRA2011-05-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/261Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 46 No 1 (2006): RCA; 195 - 214Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 46 n. 1 (2006): RCA; 195 - 2142177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
