Determination of suitable sampling methods for study of canopy cover in the Oak Forest
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2013, Vol 1, Issue 4
Abstract
To detection of suitable sampling method to study tree canopy cover in the northern Zagros forest, Baneeh region forest, Kurdistan province, and west of Iran was selected. 40 square sample plots one hectare (100×100 m) were selected and perfect inventoried. In every sample plot the position of tree, kind of species and two diameter of crown (m) were recorded. To study of canopy cover different sampling methods (rectangular sample with 20×50 m and 10×50, random sampling method with 40, 50 and 60 circle sample plots which everyone was 1000 m2) compered the prefect inventory. To determination of suitable sampling for study of canopy cover used the %E2 ×T indexes. Results showed that the rectangular sample with 20×50 m sample methods was the best methods and have maximum of accuracy. Overall results showed that the rectangular sample with 20×50 m sampling methods was (have minimum of time and %E2×T criteria) the suitable methods to study of canopy cover (%).
