Technical feasibility of forest management

Abstract

The Cerrado domain is considered as one of the global hotspots, although studies upon management in this vegetation type have many gaps in the forest literature. Thus, it’s important to propose viable alternatives to its use. This study aimed to evaluate the technical feasibility of forest management in a legal reserve of cerrado sensu stricto in Minas Gerais state, as support to the local increased demand for firewood. A forest inventory was applied from systematic samplings of 10 plots, based on the diameter criteria at 0.30 m above ground (DAG) ≥ than 5 cm. The Shannon diversity index (H') and Pielou's equability (J) were used. Furthermore, diametric distribution models and the diameter classes were evaluated by De Liocourt quotient. We observed that the Shannon diversity was 2.61 nats.ind-¹ and the Pielou (J) equability was 0.74. The De Liocourt quotient showed a non-constant mean value of 1.97 between the diameter classes. None of the fitted models showed results likewise the frequency observed in the study. The total wood volume estimated was 2,189.6765 m³. The study area possibly suffered anthropic interventions, resulting both low volumetric yield and species diversity. Thus, the forest management to the legal reserve area was considered unfeasible, as it does not present technical sustainability.
