Espécies com vocação para facilitar processos de restauração espontânea de ecossistemas perturbados na vertente atlântica da Serra do Mar, Piraí - RJ

Abstract

Disturbed Ecosystems present floristic composition changed, with a predominance of herbaceous vegetation, the soils are depleted, shallow, stony, with low infiltration and erosion presenting with different levels of Geodynamics. The individuals forest that colonized and settled in these environments, were considered rustic species. They were raised and their properties were evaluated in facilitating ecosystem evolved over 28 years, where the management was the restriction of pasture. The work was carried out in sections exposed to northern, local environmentally unfavorable of the watershed of Cacaria’s river, located in the Cacaria district, Piraí (S 22 ° 43'949''W and 43 ° 50'807''), located in the southern state of Rio de Janeiro. We found 14 rustic species in disturbed ecosystems, where only 4 survived to more advanced levels of the ecosystems (Tabernaemontana laeta, Sparattosperma leucanthum, Peltophorum dubium and Guarea guidonia), resulting in the same process of succession with 584 individuals and 43 species of 28 families in an area of 1.8 hectares, may constitute natural models of ecological restoration to be used in the Atlantic Forest.
