Abstract
Knowledge of the plant distribution pattern in each region is of principles and fundamentals of vegetation survey and measurement that plays an important role in the selection of management approaches. A study was performed to determine the distribution pattern of three dominant species of Artemisi aaucheri, Kelussiao doratissima and Prangos ferulaceae in Dyshmuk region in northwestern Kohgilouyeh and Boyer Ahmad province. One hundred quadrates of 2×2 m were randomly located along six transects of 100-m length and the number of each species was recorded. Using this information, the most appropriate and accurate quadrate-based distribution indices (Green and standard Morisitat indices) were calculated. According to the results, Kelussia odoratissima and Prangos ferulaceae showed a random distribution pattern while distribution pattern of Artemisia aucheri was uniform to random.
