[ 1 ] - Investigation of Relationship between Precipitation and Temperature with Range Production of Grasslands in North and North-east of Iran

One of the most important issues in rangeland management is the estimation of carrying capacity. To estimate range production, we need to use a large number of sample plots to clip plants in a sampling scheme; therefore, due to vast area of rangelands and time and cost limitations, direct estimation of rangeland production by sampling plots is almost impossible. Since there is a strong relation...

[ 2 ] - The Effects of Plot Shape and Size on Determining the Distribution Pattern of Astragalus verus Olivier

The distribution pattern of plants is an important characteristic of plant communities, being of critical importance in ecological studies and sampling plans. This study was designed to investigate the efficiency of different shapes and sizes of quadrants to delineate the spatial patterns of Astragalus verus Olivier by using dispersion indices. At Mayan Rangeland (Khorasan Razavi), a digital ca...
