Fragility of the different ecosystems due to Invasive Alien Species (IAS) is now a major focus of global concern. The increasing threat of invasive aliens to the native flora inspired the present investigation. The study has commenced for assessment of the distribution and abundance of invasive alien plant species in the Thar desert of Bikaner Division of the northwestern Rajasthan for initiating their effective management. The aquatic ecosystems of the region is invaded by Typha angustata, Ipomoea carnea, Eichhornia crassipes, Hydrilla verticillata and Nelumbo nucifera. The desert ecosystem, especially near areas of rural as well as urban settlements, are severely invaded by Prosopis juliflora, Lantana camara, Parthenium hysterophorus, Ageratum conyzoides, Argemone Mexicana etc. The most severe infestation occurred by Prosopis juliflora, which is posing threat to survival of native biodiversity of the desert. Such IAS are major problem and obstruction for conservation of biodiversity. The main purpose of the present study was to determine the presence of potentially invasive plants within different habitat of the Thar desert of the Bikaner Division and to suggest effective management practices for mitigating their adverse impacts on native flora.
