Abstract
This study was carried out to evaluate the plant communities and plant species diversity of Biodiversity Park. Vegetation survey was completed by collection data by using the line transect and Quadrate method. A quadrate measuring 1 x 1m2 were laid on each transect (100m) to record the frequency, density, and coverage of plant species. Plant communities were determined on the basis of Importance Value Index (IVI). Floristic composition, Life form, and soil properties were also recorded. In general, the soils were poor in nutrients, slightly alkaline and sandy loamy in texture. A total of 68 plant species belonging to 23 families were recorded in study area. Phytosociological analysis of vegetation identified 13 plant communities based on IVI. Most of them were dominated by therophytes and were better adapted to xerophytic climatic conditions. Species such as Cyperus rotundus, Ochthochloa compressa, Eragrostirs barrelieri, Limeum indicum, Suaeda fruticosa, Diperygium glaucum and Lasiurus scindicus were dominated in all the identified communities. The life form and Habit of species were also determined and therophytes (39 species) and Phanerophyte (11 species) dominated in all the stands. Similarly herbs (34 species) grasses (16 species), shrubs (9 species), trees (7 species) and sedges (2 species) were varied number of species observed in the study area.
