Estoque E Dinâmica De Biomassa Arbórea Em Floresta Ombrófila Densa Na Flona Tapajós: Amazônia Oriental

Abstract: A análise das oscilações dos estoques de biomassa em florestas tropicais permite descrever o comportamento desses ecossistemas diante de alterações naturais ou antropogênicas. O objetivo deste trabalho foi avaliar o estoque e a dinâmica de biomassa no período (2007-2010) em Floresta Ombrófila Densa de duas áreas de pesquisa na FLONA - Tapajós: Amazônia oriental, denominadas Área 1 e Área 2, distantes aproximadamente 45 km uma da outra. A biomassa foi estimada através de equação alométrica e medidas de DAP, pro… Show more

“…The annual mortality rates from 2001 to 2011 found in our study (DBH ≥ 20 cm) were similar to those in other Amazon sites in managed and non-managed areas in different forest types in different periods and monitoring times (Azevedo et al, 2008;Vasconcelos et al, 2009;Salomão et al, 2007;Santos et al, 2018).…”

“…Recruitment of new trees (DBH ≥ 20 cm) between 2001 and 2011 was greater than the 2001 to 2021 annual forecasted rate, but similar to rates found by D'Oliveira et al ( 2017), 20 years after logging. Recruitment in the present study was higher than the results of De Carvalho (2004), Teixeira et al (2007), and Azevedo et al (2008) in experimental forests, or of Vasconcelos et al (2009); Souza et al (2012Souza et al ( , 2017; Salomão et al (2017); Santos et al (2018). The results obtained through the use of the Markov Chains were robust enough to evaluate the parameters of the forest dynamic from 2001 and 2011 and to predict to 2021.…”

“…For studies performed in the Amazon Biome we have: SANTOS et al (2018), in a study in mature forest in central Amazonia, acquired estimates of biomass (Bwood) of the bole wood with bark ranging between 299.60 and 29.46. tC.ha -1 , with a mean of 327.8 ± 41.9. tC.ha -1 . SALDARRIAGA et al (1988), in a study on ecological succession in the Amazon region, found wood biomass (Bwood) of the stem in four stands of mature forests ranging between 107 and 145. tC.ha -1 .…”

“…For all areas after low-impact logging, the great loss of biomass was evident in the first years after logging. Santos et al 2018, observed in the Tapajós national forest that the largest stocks of biomass are found in the classes of 30 ≤ DBH ≤ 60cm and DBH ≥ 90cm, despite the large number of individuals 10 ≤ DBH ≤ 30cm, individuals in the middle classes and higher concentrate a large accumulation of biomass. After seven years, the forest is recovering the value of biomass due to growth, both in height and in diameter of the species that remained there.…”
