Height-weight profiles of two key species to assess utilization of grasslands in Boroujen,Iran

摘要：

Introduction Considering the extent of rangelands,a rapid and accurate method is vital for regular determination of utilization.So far,several,mostly time consuming and expensive,methods have been developed to estimate rangeland utilization.Instead,the height-weight relation (Cook & Stubbendieck,1986) is a rapid approach to determine utilization.The objective of this study was to establish height-weight profiles for two key species,Bromus tomentellus and Stipa lessingiana,to assess utilization in semi-arid grassland of Boroujen,Iran.
