Investigation and Determination of the Most Suitable Method for Measuring the Production of Atriplex Lentiformis

Due to role that plays in determining rangeland capacity, production has been used in most assessment studies of rangeland. Clipping and weighing are the most precise and prevalent methods to estimate production, for which other methods have been replaced because it is time consuming and expensive. Estimating of production by area and diameter of canopy cover and volume and height of shrub is one of the appropriate methods to estimate production. The mentioned methods were used in about 50 bases of Atriplex lentiformis of different ages in. Chaparghoimeh, Ghonbad Kavoos. For each base we measured area, small and large diameter of canopy cover and volume and height. Result of this study shows that there is a suitable linear relationship between real weight, area and diameter of canopy cover and volume and estimation weight. Real weight has the highest correlation coefficient with area of canopy cover (R2 = 74%). But the real weight has the lowest correlation coefficient with estimated height (R2=42%).
