Avaliação da cobertura florestal e seleção de espécies visando à produção sustentável de madeira na Amazônia oriental brasileira.

Abstract

Manage the Amazon forest, due to the great complexity of the different environmental factors that influence through the knowledge of the structure and its relationship to diversity and forest productivity, knowledge of the remaining stock and the replacement rate of the species. Many methods are used without your correct details, sometimes important missing information to support the discussion of which species can be exploited or not. For the first chapter was made evaluation of forest sustainability by comparing the diversity of species between the periods studied using the Importance Value Index - IVI as a tool to know the behavior of each commercial species and determine the dynamics of the stock volume of forests managed by the diameter classes. In the Second Chapter, a new timber harvest proposal was discussed by interpolation volumetric points and recorded in spatial maps, checking on points which had the best volumes. In the Third Chapter, it discussed the effect of interventions occurred in the experimental area in relation to the recovery of total and commercial volume on the basal area of commercial species and new species appeared in the monitoring period. This work has as main objective to verify the behavior of a native forest after exploration, assessing the intensity and cutting cycle that enables the sustainability of a managed forest under-scheme of a polycyclic system.
