RESUMO -Este estudo teve por objetivo avaliar a seleção de árvores competidoras com base em uma parcela circular com raio de 6 m e diâmetro das árvores superior ou igual a 5 cm, no uso do fator de área basal igual a 1, de acordo com o método de Bitterlich, e na disputa por espaço e luz observados em campo. Para isso, fez-se a seleção dos fustes competidores ao redor de 24 árvores objeto, escolhidas em função de sua importância, no que concerne ao estoque de carbono e ao valor de seus produtos madeireiros e não madeireiros. Após as análises, observou-se, pelo teste L&O, que ambos os métodos avaliados apresentaram baixa correlação em uma classe de diâmetro. Isso indica que a seleção dos competidores precisa ser mais estudada.Palavras-chave: Floresta Estacional Semidecidual; Índices de competição; Fator de área basal. EVALUATING DIFFERENT METHODS TO SELECT COMPETITORS AT INDIVIDUAL TREE LEVEL IN A SEMIDECIDUOUS FORESTABSTRACT -The objective of this study was to evaluate the selection of competing trees based on a circular plot with a radius of 6 meters and diameter of trees equal or superior to 5 cm; in the use of a basal area factor equal to 1, according to the Bitterlich's method; and based on the competition for space and light observed in the field. For this, there was the selection of stem competitors of about 24 trees, chosen due to their importance in relation to the carbon stock and value of their wood and non-wood products. After analysis, it was observed by the L&O test that both the evaluated methods showed low correlation in a diameter class. This indicates that the selection of competing trees needs to be more studied.

“…Twenty 10x50 m plots were inventoried in which all the stems with dbh > 5 cm cm were measured and identified botanically in 2010 and 2015. The species were classified into ecological groups according to the division proposed by Gandolfi et al (1995) and used in other studies such as Callegaro et al 2015, Figueiredo et al (2013) and Figueiredo et al (2015), in which they were presented as pioneer (P), early secondary (Si), late secondary (St) and species without classification (Sc).…”

Growth and yield modeling at the diameter distribution level is an important tool to understand forest dynamics and to predict whether a forest will act as a CO2 emissions source or sink. Therefore, the objective of the present study was to determine the diameter distribution and carbon stock of a forest fragment using the Markov chain to evaluate the impact of growth dynamics on forest carbon capture. Twenty plots of 10x50m were inventoried, between 2010 and 2015, counting the stems with dbh > 5 cm. Diameter distribution was projected for 2015 and 2020, considering the whole fragment and the ecological groups (pioneer and non-pioneer tree species). The volume was determined using allometric equation while biomass and carbon was determined by multiplying the volume by the basic wood density and the carbon content, respectively. The diameter distribution estimated for the fragment and ecological groups did not differ statistically from the values observed using the Kolmogorov-Smirnov test (p-value < 0.05). The number of stems ha-1 estimated in the fragment was from 1,692 in 2015 to 1,841 in 2020. For the pioneer and non-pioneer species, the number of stems ha-1 was from 476 and 1,203 in 2015 to 472 and 1,362 in 2020, respectively. The carbon stock increased 5.69 MgC ha-1, with the greater contribution coming from the non-pioneer species. Therefore, it was concluded that the diameter distribution would remain “J-inverted” and the forest fragment would continue to act as a carbon sink over the coming years.

“…It presents great floristic diversity and has been a constant target of deforestation, with only around 4% of its original forest cover remaining (Brasil, 2007). Despite its ecological importance, few studies have attempted to quantify the carbon stock in this physiognomy (Scolforo et al, 2008a;Ribeiro et al, 2009;Souza et al, 2012b;Amaro et al, 2013;Torres et al, 2013;Carvalho et al, 2014;Gaspar et al, 2014;Figueiredo et al, 2015).…”

Biomass and Carbon in a Seasonal Semideciduous Forest in Minas Gerais

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 .
