“…Esse fato amplia a ênfase nos últimos anos para o papel das florestas naturais na captura de CO2, corroborado pela avaliação do estoque de carbono em formações de Floresta Ombrófila Densa (CUNHA et al, 2009;SILVEIRA, 2010) e Mista (WEBER et al, 2005;AMARAL et al, 2010;WATZLAWICK et al, 2012;MOGNON et al, 2013;LIPINSKI et al, 2017;), Floresta Estacional Semidecidual (RIBEIRO et al, 2009;SOUZA et al, 2011;AMARO et al, 2013;DINIZ et al, 2015;) e biomas como Cerrado (MORAIS et al, 2013) e Caatinga (SANTOS et al, 2016).…”

Diante da intensificação das emissões de gases do efeito estufa, as formações florestais possuem papel importante na fixação do dióxido de carbono (CO2) da atmosfera. Diferentes espécies, famílias e grupos ecológicos contribuem de forma distinta no potencial de estoque de carbono. Com isso, objetivou-se nesse trabalho estimar a biomassa e o carbono estocado em espécies florestais presentes em uma Unidade de Conservação no bioma Mata Atlântica. Foram alocados 40 pontos quadrantes no Parque Natural Municipal do Curió, Paracambi, RJ, sendo mensuradas as variáveis DAP e altura total das árvores pertencentes a cada ponto, além da coleta de baguetas via sonda de Pressler, nas alturas 0,70; 1,30 e 1,80 m do solo. Caracterizou-se a estrutura horizontal, definindo as espécies de maior valor de importância e seus grupos ecológicos. A biomassa foi quantificada e o estoque de carbono (EC) foi estimado (50% da biomassa). O CO2 equivalente estocado foi obtido pelo produto entre o fator 3,67 e o EC. Como resultado, foram mensuradas 160 árvores e identificadas 57 espécies. Os estoques de biomassa e carbono estimados foram 212,39 e 106,19 t.ha-1 respectivamente, sendo o grupo das espécies secundárias responsável por 38,95% desse estoque. A espécie com maior representatividade na fixação do CO2 foi Plathymenia reticulata Benth. O CO2 equivalente estocado no trecho estudado totaliza 3.893,81 toneladas. A imobilização de CO2 pelas Unidades de Conservação corresponde a uma alternativa em projetos de Pagamentos por Serviços Ambientais, contribuindo para a manutenção dessas áreas e conservação da biodiversidade.

“…In a study by Figueiredo et al (2015), in a semideciduous seasonal forest, in the middle stage of regeneration, it was found an estimate of PAI in carbon of 0.994 MgC ha -1 year -1 , from 1994 to 2008, considering only the stem. Souza et al (2011) found an PAI in carbon of 0.14 MgC ha -1 year -1 for a semideciduous seasonal forest, also in the middle stage of regeneration, from 2002 to 2007, considering stems and branches. The PAI estimates found by these authors were much lower than those found in this study.…”

The secondary Atlantic forests play an important role in the context of climate change, acting as a carbon sink for the atmosphere. However, these forests can become a carbon source in case of increased tree mortality. Knowing this change is possible through continuous forest inventories that provide information on the dynamics of tree growth. Thus, the objective of this study was to evaluate the carbon growth dynamics of a Seasonal Semideciduous Forest fragment, with 44.11 ha, located in the Parque Tecnológico de Viçosa - MG. The forest inventories were carried out in twenty plots of 10 m x 50 m, in the years of 2010 and 2015, where all stems with dbh ≥ 5 cm were measured, botanically identified and classified in ecological groups. The stem volume was obtained through volumetric equation. Biomass and carbon stock were quantified for compartments located above the ground (stem, branches and leaves) and below ground (roots). The dynamics of carbon growth were evaluated by Gross Increment (GI) and Periodic Annual Increment in carbon of the species (PAI). The GI was 12.72 MgC ha-1, including the carbon from the stems that were recruited and died during the monitoring period. The carbon stock increased 10.01 MgC ha-1, resulting in an PAI of 2.00 MgC ha-1 year-1. Thus, it is concluded that the forest fragment present positive carbon stock growth due to successional progression, ratifying the importance of secondary forest of the Atlantic forest in the mitigation of greenhouse gases in the atmosphere.

“…In natural forest fragments, the differences observed between sites in wood, biomass, and carbon stocks in the tree component can be attributed to differences in floristic composition, diameter structure, and successional stage [25][26][27]37,57]. Moreover, the specific characteristics of each vegetation type can contribute to the different biomass stocks at each site, as the previous land use history of each site might also affect the biomass accumulation rates [27].…”

Reliable estimates of tree growth and wood yield are fundamental to support the management of restored forests and better reconcile the objectives of recovering biodiversity with the provision of ecosystem services. In this study, wood standing volumes and tree biomass stocks were estimated in different ecological restoration systems and at two sites with contrasting soil fertility, in order to evaluate the potential trade-offs between biodiversity and forest production. At each site, a complete randomized block design, with three replications of six treatments, was established in 1997–1998: direct seeding (DIRS), high-diversity tree plantation (HDIV), modified “Taungya” agroforestry system (AFS), mixed plantation with timber and firewood species (MIX), managed agroforestry system (AFSm) and managed mixed plantation (MIXm). We inventoried all trees with diameter at breast height (DBH) ≥ 5 cm in 450 m2 per treatment per plot, 19–20 years after establishment, using site-specific allometric models. Significant site effects were found for tree height, tree density and wood volume. Restoration systems (treatments) affected forest structure and forest productivity. Higher wood stock and biomass tree were observed in the less complex system (DIRS), while AFSm and HDIV reconciled higher species richness and diversity with good wood volume yields and tree biomass.
