Abstract

this study aims at determining the best SHAPE OF SAMPLE PLOT for NATURAL REGENERATIONs investigation of ORIENTAL BEECH in Nowshahr Kheiroudkenar forest. Eight compartments were selected in NAMKHANEH DISTRICT for carrying out of this study. A 150×200 m grid was planed and was laid out on topographic map. According to the extent of study area (299.4 ha) and the dimensions of the grid, 94 sample points were obtained. Each of these points is studied with four sample shapes: First; circular shape with area of 75 m2, Second; rectangular shape with area of 75 m2, Third; cluster shape with three units, each with area of 25 m2, Fourth; cluster shape with five units, each with area of 15 m2. After ground control of sample points in the field, four mentioned shapes were established and regenerations with less than 1.3 m height in the plots were counted. By the way, starting and ending time of sampling in each shape were recorded to compare the time of four shapes establishment. After data collection for each shape, the term E%2×T was calculated separately and used as a comparative criterion. On the basis of conclusions of this study, cluster shape with three units had the lowest E% and circular shape had the lowest (90356) E%2×T.
