Resumo: The Deciduous Seasonal Forest of the Northeast region of the state of Goiás is one of the few types of forest formations in the Cerrado biome, which may occur in areas of limestone outcrops. Generally it has a higher biomass of tree species than the contiguous cerrado. This study was carried out in an undisturbed area of forest (Flor Ermo Farm) and in others four areas of disturbed forests: Formosa, Traçadal, Manguinha and Conceição Mocambo Farm. The study aimed to estimate the basal area and the sampling intensity needed to use Bitterlich´s relascope in the deciduous forests. Estimates of basal area of the plots ranged from 23 to 24 m²/ha in the disturbed forests up to a maximum of 29.3 m²/ha in the undisturbed one. Forests with high disturbance showed very small variation of the standard deviation curve for the sampled points when compared to the area with low disturbance level. For a confidence level of 95% estimate of the mean, 20 sampling points with the relascope can be enough to sample the basal area in this kind of vegetation.

Este estudo foi desenvolvido em uma área de floresta intacta (Fazenda Flor Ermo) e em quatro áreas de floresta perturbada (Fazendas Formosa, Traçadal, Manguinha e Conçeição Mocambo). O objetivo foi estimar a área basal e a intensidade amostral utilizando o relascópio de Bitterlich em florestas deciduais. A área basal foi de 29,3 m²/ha na floresta intacta e de 23 a 24 m²/ha nas perturbadas. As florestas com perturbação acentuada apresentaram curvas de distribuição do desvio padrão dos pontos de amostragem com pequena variação comparada com a curvas das áreas com baixo nível de perturbação. Para um limite de confiança de 95 % de probabilidade de confiança para a estimativa da média, 20 unidades amostrais com o relascópio podem ser suficientes para amostrar satisfatoriamente a área basal nesse tipo de vegetação.Universidade Federal de Santa Maria2004-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/181610.5902/198050981816Ciência Florestal; Vol. 14 No. 2 (2004); 169-176Ciência Florestal; v. 14 n. 2 (2004); 169-1761980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1816/1080Nascimento, André R.
