Wood volume and biomass of a fragment of the Mata Atlântica at Santa Maria de Jetibá county, state of Espirito Santo, Brazil

Abstract

The paper analyzed the floristic, wood volume and their biomass in two areas of the Atlantic Forest, located at the Reserva Biológica Sítio Palmares in Santa Maria de Jetibá county in state of Espirito Santo. It was measure each six plots in one preserved areas (primary forest) and in one 33 years old on natural regeneration process (secondary forest). It was measured all the trees with over 5 cm DBH. At the area primary forest were found 341 trees distributed in 70 species and 32 families. The tree population presented an average of 14.82 cm DBH and a basal area of 43.60 m2 ha-1, corresponding to wood trunk and branches of 518 m3 ha-1 equivalent to 397,674 kg ha-1. The secondary forest on natural regeneration had 195 trees distributed in 17 species and 14 families, with a DBH of 12.4 cm. The basal area was 12.5 m2 ha-1, corresponding to 93 m3 ha-1 of wood volume and 54,631 kg ha-1 of biomass.
