Biomass and Carbon in a Seasonal Semideciduous Forest in Minas Gerais

Abstract

The objective of the present study was to quantify the biomass and carbon stock in a Seasonal Semideciduous Forest remnant in southern Minas Gerais. Forest inventory data taken between 2010 and 2013 in permanent plots, was used to estimate biomass with an allometric equation. Basic wood density (Db) and carbon content were determined in the laboratory and the carbon stock was obtained by multiplying biomass by carbon content. The species with the lowest and highest Db were Nectandra lanceolata (0.38 g cm-3) and Machaerium villosum (0.77 g cm-3). The species that showed the lowest and highest carbon content values were Casearia decandra (41.85%) and Nectandra oppositifolia (46.57%). The biomass stock for the area was 126.92 ± 0.09 t ha-1 , which corresponded to 55.91 ± 0.05 t ha-1 of carbon stock and a periodic annual increment of 3.07 t ha-1 year-1 .

Carbono No Solo E No Estrato Arbóreo Em Áreas De Manejo De Florestas Nativas No Cerrado

“…Segundo esses autores, as florestas estacionais da Faixa Sul apresentam produtividade em volume, biomassa e carbono superiores à do cerrado stricto sensu do Tocantins e do resto do Brasil, e similar à de florestas estacionais do Bioma Cerrado da América Central e do mundo. Silva et al (2018) trabalhando em uma Floresta Estacional Semidecidual encontraram valores para carbono orgânico de 55,91 ton ha -1 , respectivamente. Silva (2014), trabalhando em uma área em restauração de uma Floresta Estacional Semidecidual obteve valores de carbono orgânico correspondentes a 49,73 ton ha -¹.…”

WOOD VOLUMETRY OF Tachigali vulgaris PURE PLANTATIONS IN DIFFERENT PLANTING SPACINGS

“…This volume represented the sum of commercial values with bark of each tree trunk. For this purpose, the use of equivalent diameter (d eq ) was needed for forked trees (SILVA et al, 2018;DOMBROSKI;PINTO, 2019). This diameter was obtained by the square root of the sum of each squared diameter at breast height of tree trunks, representing the equivalent diameter to a given segmental area (CAMPOS & LEITE, 2017).…”

Diversidade de espécies arbóreas entre fragmentos de Floresta Estacional Semidecidual, Minas Gerais, Brasil

“…Mesmo com amplitudes crescentes nas duas áreas há um desequilíbrio entre a primeira classe diamétrica que teve a maior concentração de indivíduos sendo superior às outras classes juntas, registrando um acentuado decréscimo na frequência de indivíduos com o aumento das classes (figura 2), esse resultado é comumente encontrado em vários estudos em florestas semidecíduas (SILVA et al, 2018;SILVA et al, 2019;COSTA et al, 2020).…”
