Produção de uma floresta natural em Santa Maria, RS.

Abstract

O presente trabalho teve por objetivo estudar o volume comercial e total por hectare, distribuição de freqüência e qualidade da madeira da floresta do Campo de Instrução do Exército de Santa Maria, município de Santa Maria, Rio Grande do Sul. Foram encontradas quarenta e oito espécies, onde os maiores volumes pertencem as espécies Nectandra megapotamica, Patagonula americana e Ficus luschnathiana. A distribuição de freqüências por classe diamétrica foi ajustada a Função de Meyer, sendo obtida Constante Regulativa (q) de 1,7238, normal para este tipo florestal. A qualidade média da madeira foi considerada boa. O volume comercial com casca foi de 148,6 m3/ha, correspondente a uma área basal de 28,8 m2/ha.

Generic and specific stem volume models for three subtropical forest types in southern Brazil

“…In Brazil, there is a clear trend for using this kind of transformation in volume model adjustment for native forests. The logarithmic model by Schumacher and Hall (1933) Logarithmic models constructed by the first forest inventories of southern Brazil (Brasil 1983;Netto 1984) are often used for broadleaved species (Glufke et al 1994;Vaccaro 2002;Figueiredo-Filho et al 2006) and for Brazilian pine (Figueiredo-Filho et al 2006;Vibrans et al 2012b). Machado et al (2008) reported that Schumacher and Hall (1933) model produced most accurate predictions for the cultural and ecological important species M. scabrella Benth.…”

Estimate of the diameter distribution in Mixed Ombrophylous Forest fragment with the Meyer's function

“…HESS et al (2010), in the city of Lages, SC, found the value of 1,33 for the adjusted quotient of Lioucourt, in FOM. GLUFKE et al (1994), in the city of Santa Maria, RS, found the value of 1.72.…”

Importance of the review on floristic and phytosociological studies of the arboreal stratum of the seasonal deciduous forest of the Serra Geral slope, Rio Grande do Sul, Brazil, to support proposals for sustainable management

“…Machado and Longhi (1990) on a hill, Farias et al (1994) in military area, Longhi et al (1999) and Hack et al (2005) on rural properties, Longhi et al (2000) in an association, Jarenkow and Waechter (2001) The quantitative-qualitative evaluation of forest resources is the objective of Brena (2001), while Glufke et al (1994) analyze the production of a natural SDF in Santa Maria (commercial volume and wood quality). The forest fragments in dairy farms and their relation with the sustainability of the activity are the themes of Markus (2014) specifically in permanent preservation Zerwes et al : Importance of the review on floristic and phytosociological studies of the arboreal stratum of the seasonal deciduous forest of the Serra Geral slope, Rio Grande do Sul, Brazil, to support proposals for sustainable management areas (APP), and of Zerwes (2016), in the APP and areas proposed for legal reserve.…”

“…T. elegans is also a species of understory. A. edulis, C. sylvestris and C. vernalis stand out in secondary forests because they are light demanding species, whereas E. ramboi, L. divaricata and N. megapotamica are common species with great dominance in the canopy of secondary and primary forests (GLUFKE et al, 1994;GRINGS;BRACK, 2009). G. klotzschiana presents high IVI in alluvial and/or riverine forests, where it adapts to the hydromorphic environment (BUDKE, 2007), as well as M. paraguariense (TEIXEIRA et al, 2014).…”
