Influence of diameter measuring height on the adjustment of volume and biomass equations of cerrado in minas gerais

Abstract: Different tree diameter measuring heights are displayed in the literature, which in some cases can lead to different results in the final estimates, if the model used is not compatible with the diameter measurement height. The aim of this study was to evaluate and validate equations of volume and biomass, adjusted by Goal Programming and regression by Ordinary Least Squares Method for the Cerrado Sensu Stricto and Campo Cerrado in Minas Gerais state, using information on diameters measured at 0. 10, 0.30 and 1… Show more

“…Por outro lado, estudos que utilizam apenas a medição do diâmetro do toco tem sido realizados visando sua aplicação na fiscalização de áreas desmatadas ou em locais que apresentam irregularidades de corte no plano de manejo, uma vez que os tocos, na maioria das vezes, é o que resta da exploração florestal (ROLIM, et al, 2006;LEITE, 2008;MORAIS, et al, 2014;CAETANO, et al, 2016;) O objetivo deste estudo foi ajustar e validar equações de volume utilizando informações do dt e dap, para uma espécie de valor comercial, no norte de Mato Grosso.…”

“…Quantitative studies have also been developed in order to identify growth and productivity parameters in the various regions of occurrence of this vegetation (Rufini et al, 2010;Reis et al, 2015;Silveira et al, 2019b). Volumetric reviews of timber potential, biomass and carbon stocks are being held either by environmental agencies and academic institutions, while the private sector carries out quantitative surveys designed to support plans for sustainable management and operations for exploration of timber resources (Alvarenga et al, 2012;Morais et al, 1995;Silveira et al, 2019b). Estimating wood volume and biomass accurately and establishing suitable models can provide a scientific basis for determining reasonable stocking capacity (Yang et al, 2018), with implications to regional and global reports on biomass, carbon stocks, and their changes.…”

“…It is important to note that different countries adopt different measuring points (Morais et al, 2014). In most countries, the DBH is measured at 1.30 m above ground level, but 1.37 is used in the USA and 1.2 m is used in Japan and Korea (Van and Akça, 2007).…”
