Métodos de estratificação vertical em Floresta Estacional Semidecidual

Abstract: O presente estudo foi realizado em um fragmento de Floresta Estacional Semidecidual de 52 ha, conhecido como Floresta do Rosal, no município de Guaçuí-ES e teve como objetivo testar metodologias de estratificação vertical, avaliando a adequação dessas metodologias baseada na classificação sucessional ecológica das espécies. Para tanto, empregou-se o método de amostragem de área fixa, sendo distribuídas 16 parcelas de 600 m 2 , de forma sistemática no campo. Todos os indivíduos com DAP ≥ 5 cm tiveram suas altur… Show more

“…This is due to the use of central tendency measuring (average with standard deviation), a result that is expected for this method. Paula et al (2004) and Curto et al (2013) found most individuals in the middle stratum -81.3% and 75.3% respectively -confirming those results.…”

“…This method's results were the closest to the standard method in relation to individual percentages (Table 2). Curto et al (2013) also tested this method on a Semideciduous Seasonal Forest fragment and, unlike this study, classified 50.1% of the trees in the inferior stratum, 42.7% in the middle, and only 7.2% in the superior stratum.…”

“…Structural studies are important indicators of the sustainability of forest activities (Souza et al 2003) since they generate information about the dominance that certain species exert over others. This, in terms of competition for light, contributes to identifying the ecological behavior and habits of these species in the different height strata, thus allowing understanding the strategies of regeneration, growth and survival (Curto et al 2013). This information is essential, among other things, for the definition of conservation policies, for degraded area recovery programs (Brito et al 2007) and, above all, for the definition of silvicultural treatments and the assessment of impacts from logging activities (Calegário et al 1994), thus encouraging more reliable forestry planning.…”

“…Although there is awareness of the importance of vertical structures for decision making, most studies that address the phytosociological characterization of forests in the Amazon only use tables of importance value that characterize horizontal structures and exclude vertical ones (Curto et al 2013). The main reasons for its exclusion are the difficulty in analyzing them (Curto et al 2013) and, mainly, the determination of the lower and upper limits of the strata, which are most often controversial and imperceptible (Durigan et al 2000), with young trees of the upper stratum growing in the lower and mean strata. It is also worth noting that these limits are the basis for calculating the absolute and relative sociological positions and the extended importance values of the species, which characterize the vertical structures (Freitas y Magalhães 2012).…”
