Yadav, D. K.
The present study was aimed at quantifying the species structure and diversity in Achanakmar- Amarkantak Biosphere Reserve. Four sites characterized by varying vegetation attributes and representative of the region were selected. One-hectare, permanent plot was established on each of the site and enumeration was car-ried out by stratified random sampling techinique. The forest sites are characterized by poor species composition. A sum of 2440 trees representing 23 species and 17 families were encountered. Tree, sapling and seedling density (stems ha-1) ranged between 260 - 810, 7500 - 35000 and 25000 - 67500, respectively while the basal cover (m2 ha- 1) ranged between 9.96 - 41.6, 0.86 - 5.07 and 0.28 - 0.96, respectively. Species diversity was highest on the dense site and low on medium site. Beta diversity was highest on degraded site. The presence of a large number of seed-lings indicates the great potential source for future sustainable regeneration, provided by appropriate management regime to protect the forest from degradation and conserve the biodiversity.
