Species
Dolphins, Gharials and Otters form the major flagship species of freshwater environments. These species as high-order carnivores at the top of their small niche eco-systems are indicators to the health of the ecosystem.
In spite of their ecological importance, freshwater environments belong to the most threatened ecosystems worldwide as they underlie a severe use conflict by human demands on water supply; consequently biodiversity is affected with drastic reductions in undisturbed sites. The documentation of past, present and potential future distribution of these flagship species is vital for developing conservation programmes.
