biodiversity and human well-being is interrelated and is
being promoted increasingly through the concept of
ecosystem services provided by the species (MEA, 2005;
McNeely and Mainka, 2009) The diversity is attributed to
many reasons, viz., the geomorphology, consisting of

a variety of torrential hill streams, rivers, lakes and
