The monsoon rain brings a green carpet of landscape to Thar Desert including Karoonjhar mountains range. We explored Nagarparkar, District Tharparkar, Sindh to record post monsoon botanical inventory of the region. The study confirmed 89 plant species of 26 plant families. The vegetation was dominated by Poaceae (18 spp.) and Fabaceae (15 spp.) families. About two third of the families were represented by single species. The vegetation was rich with grasses and herbs making about 60% of the species while the rest includes tress shrubs and subshrubs. The lifespan analysis revealed the dominance of perennials. The life form spectrum shows the abundance of Phanerophytes (30%), Chamaephyte (28%) and Therophyte (25%) across the region. The present study demonstrates vegetation variations triggered by monsoon down pours and indicates the presence of various microhabitats in the study area. The current inventory would be useful for further ecological studies and conservation of species and habitats. These records would help to detect invasive species, their distribution and other environmental impacts on plant species in future.
