Abstract

Rangelands are natural ecosystems containing great genetic resources and plant species diversity having profound effects on stability of the rangelands. SPECIES RICHNESS and biological diversity have been declined throughout the world as a result of human activities. National parks and protected areas are an attempt to conserve the remaining species. Measuring SPECIES RICHNESS is important to understand resource condition but heterogeneity in plant distribution make inventories difficult. This study aimed to compare two methods of measuring SPECIES RICHNESS (Whittaker and Modified Whittaker plot) for the Poshtah Mayvaleh in ILAM, Iran.This study was carried out in two grassland and shrubland vegetation using six replicates. A total of 154 plant species was found belong to 121 genus and 35 plant families. Among them Asteraceae were abundant. The result of this study shows that there is a significant difference between two methods in measuring SPECIES RICHNESS for both vegetation types. Also the Modified Whittaker plot showed better estimating of SPECIES RICHNESS by plot area according to the result of regression analysis.
