Abstract
In this study we analysed herbaceous species diversity in Andhra University campus by using minimum quadrat size method. For this analysis we used 10 × 10 sq. cm as the minimum size of the quadrat and we gradually increased the quadrate size and the count was repeated each time. We repeated the same procedure for 20 × 20 sq. cm, 30 × 30 sq. cm, 40 × 40 sq. cm and so on till 1 × 1 sq. metre area is covered and we noted the number of additional species every time. The vegetation analysis was carried out by total 10, 1 m × 1m sample plots placed randomly from study area. From the collected data we obtained species-area curve and the curve shows that 80 × 80 sq. cm size is the minimum size of quadrat for herbaceous species diversity analysis in Andhra University, Andhra Pradesh, India.
