Horizontal structure analysis by Kernel density as basis to forest management in Amazonia
The present work aimed to characterize the horizontal structure of an area of primary Amazonian Forest and the spatial distribution of the species Goupia glabra (Aubl.), Qualea spp. and Dipteryx odorata (Aubl.) Willd. through the analysis of the Kernel density, aiming to support the planning of forest management. The study area is located in Santa Carmem, microregion of Sinop, state of Mato Grosso (1,024 ha), where all individuals with a diameter of 1,30 m from the ground ≥ 30 cm were measured. The absolute and relative densities, frequencies and dominances were calculated, in addition to the importance and coverage value indices. Kernel density and species level dispersion analysis were obtained using the ArcGIS program. The area was classified by the Shannon index as low diversity and more than 50% of the species were classified with a tendency to cluster. Qualea spp. presented the highest values "‹"‹for all analyzed parameters. It was observed that the highest concentration of individuals occurs in the diametric classes that can be exploited. The application of Kernel density appears as a promising tool for planning sustainable forest management, allowing the definition of preferential zones for sustainable exploitation.
