- Abstract
Traditional Statistical methods applied to forest inventories have not sufficiently assessed relationships among sampling units. This study intended to compare the resulting estimates derived from a geostatistical interpolator and from a traditional forest inventory. The study area encompassed a total of 116 hectares of Eucalyptus urophylla, located in Rio Verde/ GO, Brazil. This is a 6.5 years old forest, planted in 2005, with spacing of 2.8 m× 1.8 m. In this study, we sampled 23 plots of 400 m2 each. Also, we randomly allocated 13 of 23 plots to assess the interpolator method. The remaining 10 plots were used to validate the interpolation results and to compare with data derived from the forest inventory. This research results indicate that the difference between Ordinary Kriging and traditional inventory estimates was not significantly different. Therefore, the method was successfully applied to estimate the volume in forest land and can pontentially support volume estimation throughout an entire area of interest.
