“Conservation of Heritage Sites in India: An Historical Perspective”
The Western Ghats , one of the well-known biodiversity hotspots of the world, harbours 289 species of freshwater fish of which 119 are endemic. The ecosystems in this region have been, over the past 150 years or so, experiencing tumultuous changes due to the ever-increasing human impacts. Among various anthropogenic impacts, impounding of waters for electricity generation seems to have significantly altered terrestrial as well as aquatic ecosystems and associated biota including fish fauna. In this regard, a study was conducted in Sharavathi river of central Western Ghats to understand fish species composition with respect to landscape dynamics. Of the 64 fish species recorded, 25 were exclusive to the tributary streams, 29 to the reservoir and 10 common to both. Among these, 18 species were endemic to the Western Ghats and 10 to peninsular India . The study, carried out using a combination of remote sensing data as well as field investigations, shows that the streams having their catchments covered with evergreen to semi-evergreen forests, having high levels of evergreenness and endemic tree species of Western Ghats , were also richer in fish diversity and endemism compared to those catchments with other kinds of vegetation. It also highlights that endangered and endemic fish species are precariously clinging onto the stream habitats where patches of primeval forests, though degraded substantially, are still persisting. This illustrates the composition and a distribution of fish species have strong association with the kind of terrestrial landscape elements and highlights the importance of landscape approach to conservation and management of aquatic ecosystems. Occurrence of endangered, endemic and discovery of two new species of Schistura genus re-affirms ‘hottest hotspot’ status of the Western Ghats, a repository of biological wealth of rare kind, both in its aquatic and terrestrial ecosystems.
