Does scale matter for Lantana camara invasion in the Indian floodplains: A perspective
Anjali Mehra, Ridhima Solanki
Invasion is a renowned threat to global biodiversity, the process being triggered and facilitated by species-specific as well as site-specific characteristics. Floodplains are ecologically unique ecosystems which are also dynamic in nature. Invasion dynamics across these ecosystems does not only follows a different approach but are highly variable in terms of species establishment and spread. Literature suggests that two schools of thoughts can be derived for these riverine habitats regarding invasion; first, that periodic flooding and inundation limits the growth of invasive plants and second, that it may even facilitate habitat susceptibility to invasion. Taking the case study of the tropical invader Lantana camara along with some other major invaders of the Indian floodplains we try to assess the vulnerability of such habitats to these species and infer how site characteristics influence invasion at a local as well as at regional scale.
