Abstract

Precise quantitative information of the young forest stands is necessary in their scientific and technical management and direction of the forest stands toward sustainability. In PLANTATIONs, the working unit can be a single tree rather than the area, or the smaller areas of sampling can be used for measurement. N-TREE SAMPLING METHOD is one of the distance techniques used for measuring the quantitative and qualitative characteristics in forest stands. In this study N-TREE SAMPLING METHODs (3, 4, 5, 6, 7, 8, 9 and 10) were assessed to measure number, basal area and VOLUME PER HECTARE in a 12-ha PLANTATION in the north of Iran. At first the PLANTATION was fully callipered. Then a 50×50 m grid was determined for N-TREE SAMPLING METHOD application. The result of t-test showed that mean in BASAL AREA PER HECTARE estimated by Prodan's estimator, in 5, 6 and 7 trees had significant difference with 100% inventory, but means estimation of these characteristics from other methods was acceptable. Estimating means in the number per hectare and volume in hectare by Prodan's estimator did not have any significant difference with 100% inventory in the all of N-TREE SAMPLING METHODs. At last, using E%2×T, the 4 tree distance sampling method was suitable for sampling in populos delteoides PLANTATIONs.
