The aim was to study forest dynamics - the rates of recruitment, growth and mortality - in addition to carbon storage in an area of primary forest, without any intervention. The surveys were conducted in the years 2005, 2007 and 2010 in 15 permanent plots of 1 hectare each. There, all trees with diameter at breast height (DBH) above 10 cm were measured. We calculated the rates of recruitment and mortality, the periodic annual increments (PAIs) in terms of DBH, basal area and volume, fresh and dry biomass above the soil and total carbon storage in the vegetation. The recruitment rates were 2.0 percent and 1.8 percent, and mortality were 0.95 percent and 1.3 percent for the periods between 2005 and 2007 and 2007 and 2010, respectively. The volume was 345.62 m3 ha-1 for the year 2005, rising to 360.67 m3 ha-1 in 2010 with PAIs of 4.32 m3 ha-1 yr-1 between 2005 and 2007 and 1.31 m3 ha-1 yr-1 between 2007 and 2010. The total carbon storage increased from 173.63 t C ha-1 in 2005 to 181.01 t C ha-1 in 2010, confirming that the forest accumulated carbon in the period, acting as a sink. Este trabalho analisou dados de três inventários florestais realizados na área da Floresta Experimental, pertencente à Embrapa Amazônia Ocidental e localizada no km 54 da BR-174, em Manaus/AM. O objetivo foi estudar a dinâmica da floresta - taxas de incremento, recrutamento e mortalidade - além do estoque de carbono, em uma área de floresta primária, sem qualquer tipo de intervenção. Os inventários foram realizados nos anos de 2005, 2007 e 2010, em 15 parcelas permanentes de 1 hectare cada, onde foram mensuradas todas as árvores com diâmetro a 1,3 m de altura do solo (DAP) superior a 10 cm. Foram calculadas as taxas de recrutamento e mortalidade, os incrementos periódicos anuais (IPAs) em termos de DAP, área basal e volume, as biomassas fresca e seca acima do nível do solo e total e o estoque de carbono da vegetação. As taxas de recrutamento foram de 2% e 1,8% e as de mortalidade foram de 0,95% e 1,3% para os períodos entre 2005 e 2007 e 2007 e 2010, respectivamente. O volume foi de 345,62 m3 ha-1 para o ano de 2005, aumentando para 360,67 m3 ha-1 em 2010, com IPAs de 4,32 m3 ha-1 ano-1 entre 2005 e 2007 e 1,31 m3 ha-1 ano-1 entre 2007 e 2010. O estoque de carbono total teve um acréscimo de 173,63 t C ha-1 em 2005 para 181,01 t C ha-1 em 2010, confirmando que a floresta acumulou carbono no período, atuando assim como sumidouro. 2020-04-24T15:29:48Z 2020-04-24T15:29:48Z 2012 Artigo https://repositorio.inpa.gov.br/handle/1/13545 10.1590/S0044-59672012000400007 pt_BR Volume 42, Número 4, Pags. 501-506 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica |
