Carbon and biomass stocks in a fragment of cerradão in Minas Gerais state, Brazil

Abstract: ABSTRACT:This study aimed at quantifying carbon (C) and biomass stocks in shoot portion, leaf litter, roots and soil within a fragment of dense savanna 'cerradão', 158.5 ha in area, located in Minas Gerais state. Measures were quantified using dendrometric parameters obtained during the forest inventory and collection of leaf litter, root and soil samples. Furrows were dug in the soil each 100 cm long, 50 cm wide and 100 cm deep in order to collect root samples at depths of 0-30 cm, 30-50 cm and 50-100 cm, and… Show more

“…To decrease the amplitude, average values per vegetation type were generated (Table 3), and the values are similar to those shown in other studies (IPCC 2006;Caldeira et al, 2008;Vieira et al, 2010;Froufe et al, 2011;Paiva et al, 2011;Ribeiro et al, 2011;Watzlawick et al, 2012;Morais et al, 2013;Torres et al, 2013) for various vegetation types. The differences among the averages for physiognomies correlated with the number of trees and biomass stock, which means the higher the values of these characteristics, the higher the stocks of biomass and C in the litter.…”

“…This characteristic is noticed when viewing the data presented in Table 2, which presents a wide range of biomass stock values and also those for the carbon content, which therefore also affects the C stock values. However, it should be noted that the wide range of values, which demonstrate high variability, a characteristic also mentioned by Aduan and Vilela, Klink, (2003) and Watzlawick et al (2012), even taken just a single fragment (Morais et al, 2013), hinders comparison with other studies. It occurs due to the both scarce and available data, even in those studies already cited, in which almost was employed different procedures for collection as well as data analysis methods (Caldeira et al, 2008;Watzlawick et al, 2012).…”

“…Os totais estimados para produção em volume de madeira e biomassa, para o fragmento de cerradão no Parque Estadual do Lajeado, em Palmas, TO (Tabela 4), são compatíveis com os obtidos em um estudo realizado em áreas de cerradão no Estado de Minas Gerais, onde se estimaram, em média, 117 m³ ha -1 para volume de madeira total e 57 Mg ha -1 para biomassa total (Morais et al, 2013). Isso indica que ambos os modelos ajustados (regressão e de redes), em função da área basal e dos índices de vegetação obtidos a partir das imagens do satélite ResourceSat1 (IRS-P6), mostraram-se eficazes em estimar as variáveis volume de madeira e biomassa lenhosa.…”

“…Surveys indicate that in Cerrado ecosystems, the soil may concentrate more than 70% of carbon (MORAIS et al, 2013a;MORAIS et al, 2013b), however, there is a lack of studies that elucidates how the carbon in soil distributes across the forest and how strong is the dependence between carbon in different compartments, for example soil, roots and litter.…”
