摘要：
In this study adult individuals of Caryocar brasiliense (pequi) were quantified by (AA) and they were compared the traditional sampling methods. Census of adult individuals of pequi in a savannah area of 36.5ha in Black River State Park / MG was transformed in map. Thus map was divided into cells of 20x20m where five alternative of sampling were tested using simple Random Sampling, Systematic Sampling and Adaptative Cluster Sampling. Comparision among them was done by F test Graybill 1% of significance, considering precision and accuracy as parameters. All alternatives showed good accuracy, and the Adapatative Cluster Sampling with a condition of inclusion equal to 2 was most accurate.
