Nesting Sites of Birds and Spiders in the Semi-Arid Zone of Rajasthan, India

A plant when present outside its native range is termed as non-native/exotic. Some of these non-native species can outcompete the native species, becoming invasive owing to either phenotypic plasticity, absence of natural predators and pathogens, or the presence of efficient seed dispersal and allelopathic mechanisms. Successful eradication of such invasive species is almost impossible and extremely expensive, posing a significant threat to the native biodiversity and community.
