This work aimed at analyzing the feasibility of geostatic methodology in estimating the spatial pattern of paraju (Manilkara sp) wood hardness. The studied timber piece dimensions were 25 x 7 x 75 cm in width, thickness and length respectively. The two sides of the piece were divided in regular 2.5 x 2.5 cm grids comprising nine rows and twenty nine columns, totaling two hundred sixty one cells. The hardness essay was based on the Janka method with the force applied in the middle of each cell. Data were examined by descriptive statistical analyses, geostatistic and krigage interpolation. The variation coefficients were low. Spatial for wood hardness dependence was found in both sides, with higher values in side A of the piece. It was concluded that this method has practical use for providing information on sampling of timber pieces, however, there is need for further studies.
