Factors such as soil properties, altitude and topography are conditional aspects on the spatial distribution of species around the forest. The present work carried out edaphic analyzes on the edge and inside the Arboretum of Native Essences at the Hermínio Ometto University Center - Uniararas and in vegetative organs of Oeceoclades maculata, to demonstrate the influence of soil attributes on its spatial distribution. For this purpose, 20 cm deep soil samples and 10 individuals from O. maculata were collected, inside of each fragment, on its edge and interior. At the end of the investigation, the results demonstrated that Oeceoclades maculata has an aggregate distribution pattern in the studied microhabitats, considering that OM and P were present at a moderate and high positive correlation at the edge, respectively, and V% with median positive correlation for the interior, showing among all analyzed attributes distributive spatial influence.
