Analysis of the spatial distribution of buzzers (Quesada gigas Oliver) in parica stands(Schizolobium amazonicum Huber ex Ducke) in Dom Eliseu-PA. Rev. Árvore [online]. 2008, vol.32, n.2, pp. 251-258.

The objective of this study was to evaluate the occurrence of buzzers (Quesada gigas Oliver) in Parica (Schizlobium amazonicum Huber ex Ducke) stands using spatial geographic data analysis, in Dom Eliseu, Para, Brazil, based on the application of two interpolators (kriging and distance square inverse).Thus, points were set up in a density of one point for every 30 hectares, with one tree sampled per point, obeying the sample strategy conventionally used by the company which owns the reforestation stand under study. The analysis indicated that the sampling intensity utilized in this work was not sufficient to allow a strong spatial dependence of the number of buzzers/tree in the study area. Due to this low spatial dependence, the results of both interpolation methods (ordinary kriging and distance square inverse) were similar. The results of this work indicate that the sampling strategies must be improved to generate better and more precise buzzer/tree prediction maps for the Parica reforestation stand.
