Spatial distribution pattern of Euxylophora paraensis Huber in a natural managed forest in the Eastern Amazon

Abstract

The objective of this work was to characterize the spatial distribution pattern of the Euxylophora paraensis (yellowwood), to support conservation strategies of this species population in a managed 'terra firme' forest in the state of Pará. The study area is located in Fazenda Rio Capim, which belongs to The CKBV Florestal Ltda., in the municipality of Paragominas. For analyzing the spatial distribution of trees, geostatistics was used, based on the semivariogram modeling and kriging mapping. All evaluations had better adjustment to the spherical model, presenting the highest coefficient of determination in relation to the other models tested. Euxylophora paraensis presented an aggregate distribution pattern in the study forest, with spatial dependence described by the spherical model, forming tree clusters of size from 300 to 1000 m.
