Brazilian Journal of Animal and Environmental Research, online, v. 4, n. 3, p. 4721-4728, jul./set. 2021. DOI: https://doi.org/10.34188/bjaerv4n3-148.

Acesso em:.2595-573Xhttps://repositorio.ufpa.br/jspui/handle/2011/15885This research aimed to quantify the carbon stock of aboveground living vegetation in silvopastoral systems of natural regeneration practiced by family farmers in the settlement project Belo Horizonte II. The settlement is located in São Domingos do Araguaia – PA and the SSP managed from the natural regeneration of tree species constitutes an alternative for the integration of socioeconomic and environmental objectives, seeking sustainability for family farming in Southeast Pará. The biomass of the arboreal component was obtained from data from the field evaluation carried out in December 2009. The arboreal biomass per hectare was estimated from of calculation: BA = (ΣBA/1000) x (10000/plot area) and the carbon stock was estimated from ΔCBA = (BA x CF), where: ΔCBA = amount of carbon in aboveground living biomass (t C/ha); BA = aboveground living woody biomass (t DM/ha); CF = is the carbon fraction (t C /t MS) which, according to the IPCC (Intergovernmental Panel on Climate Change), defaults to 0.5. The carbon stock in the aboveground living biomass was 14.08 t C/ha, being 0.27 C t/ha and 13.81 t C/ha for the woody and non-tree vegetation biomass, respectively.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Biomassa viva acima do soloEstoque de carbonoPecuáriaLive biomass above groundCarbon stockLivestockArtigo de Periódico10.34188/bjaerv4n3-148
