Plano de reestruturação florestal e indicadores de resiliência

Abstract

The present paper studied the floristic composition, structure and volume of a forest with an area of 120.2 hectares, called Forest Secret Massif, located in the village of Figueira, Segredo s city, Rio Grande do Sul, in order to create the VCA indicator (expanded margin call), RNR indicator (natural regeneration relative) and IRF indicator (forest resilience rating) to describe the representativeness of species in the forest. Also evaluated the phenotypic aspects of the trees and the related of competition at the trees in order to propose a forest restructuring plan by removing mature trees and regenerating trees in order to improve the conditions of the forest and noble species. The three indicators, on a percentage scale, presented able to describe the representation of mature species (VCA), the regenerating species (RNR) and both the forest formation (IRF), which allowed understand the current situation of each species and will understand the changes that may be manifested in the implementation of management plans, obtaining a history. The restructuring plan has listed 13,139 mother trees, 31,820 normal trees and 10,210 trees subject to deletion (group 1), 2.095 noble trees (group 2), 2776 bagueiras (group 3), 4,538 important trees for the forest ecology maintenance (group 4) ; and 24,454 individuals subject to removal for strategic reasons, except the 7,365 needed to stand on environmental issues (group 5). The regenerating forest comes up with 18,430 trees future level 1, 56 415 trees future level 2 and 17,107 trees future level 3.
