Abstract
The Floristic composition and vegetational analysis of Keri Charhoi hills were analysed. There were 66 plants species belonging to 36 families were studied. There were 20 plant communities in spring. The soil texture of studied area was between loamy to clay loamy. The total soluble salt ranges from 0.02-0.09%, pH from 7.15-7.62, Organic matter ranges from 0.96- 1.8%, Phosphorus ranges from 2.5-10.5ppm and Potassium ranges from 104-170ppm. 58 species were palatable and 25 species were non-palatable. Index of diversity was 3.10 in spring and species richness was 0.85 in spring. The equitability was low at base then increases and again decreases at high altitude. In spring, only one community were homogenous and remaining 9 were heterogenous. Similarly, in monsoon 4 communities were homogenous and other 6 were heterogenous. Biological spectrum shows that in spring Megaphanerophytes and Hemicryptophytes were dominant. Leaf size classes were Nanophylls and Microphylls. On the basis of cluster analysis four associations were detected in charhoi hills. All communities were immature in both seasons. The investigated area has need to protect from pressure of local inhabitants and deforestation.
