Biomass equations for Castanea sativa high forest in the Northwest of Portugal IPB - Escola Superior Agrária
Patrício, Maria do Sameiro; Tomé, Margarida; Monteiro, Maria do Loreto.
There is considerable interest today in estimating the biomass of trees and forests for practical forestry issues, sustainable management, carbon and nutrient flux and other scientific purposes. For these reasons, aboveground biomass was studied in Castanea sativa high forest stands located in the Northwest of Portugal. The most widely used procedure for stand biomass evaluation is the regression estimation method, in which the stand biomass is predicted through the sum of the predicted biomass of individual trees. In this study, thirty-four old sweet chestnut trees, located in three stands, were felled, measured and weighted to evaluate the aboveground biomass by components. Several linear and nonlinear equations were fitted by the least squares method to...

Estimativa da biomassa aérea e carbono de Ilex microdonta em floresta atlântica, Paraná, Brasil. Repositório Alice
MIRANDA, B. P.; RODERJAN, C. V.; BOTOSSO, P. C.; LONGHI-SANTOS, T.; ANDRADE, V. H. F..
Conhecer o estoque de C fixado na vegetação é um dos importantes fatores para entender o balanço deste elemento nos ecossistemas e, para isso, o uso de modelos alométricos nestas estimativas é um dos meios de se obter esse tipo de dado, quando não é possível a amostragem direta de indivíduos nos ambientes. No âmbito da Floresta Ombrófila Densa no Paraná, os estudos de biomassa restringem-se aos patamares altitudinais inferiores da paisagem, inexistindo, portanto, estudos nos terços médio e superior das encostas da Serra do Mar. Neste contexto, esse trabalho teve por objetivo realizar uma estimativa dos valores de biomassa e carbono para Ilex microdonta, espécie de maior valor de importância nas comunidades altomontana da Serra do Mar, verificando se há...

Predicting of biomass in Brazilian tropical dry forest: a statistical evaluation of generic equations Anais da ABC (AABC)
LIMA,ROBSON B. DE; ALVES JÚNIOR,FRANCISCO T.; OLIVEIRA,CINTHIA P. DE; SILVA,JOSÉ A.A. DA; FERREIRA,RINALDO L.C..
ABSTRACT Dry tropical forests are a key component in the global carbon cycle and their biomass estimates depend almost exclusively of fitted equations for multi-species or individual species data. Therefore, a systematic evaluation of statistical models through validation of estimates of aboveground biomass stocks is justifiable. In this study was analyzed the capacity of generic and specific equations obtained from different locations in Mexico and Brazil, to estimate aboveground biomass at multi-species levels and for four different species. Generic equations developed in Mexico and Brazil performed better in estimating tree biomass for multi-species data. For Poincianella bracteosa and Mimosa ophthalmocentra, only the Sampaio and Silva (2005) generic...
