The 6-tree sampling method which was introduced in 1969 by Dr. Prodan was tested by the Faculty of Natural Resources at the University of Tehran in the natural forests of Northern Iran. Variations including 6-, 7-, 8- and 9-tree sampling were examned. The research shows that the tree sampling technique is not suitable for the natural forests of the northern region. Each of the 6-, 7-, 8- and 9-tree systems consistently underestimates the true population parameters.
