Each land unit in which we are living and intervening are part of a landscape unit with geographical integrity and connectivity determined by its geological and ecological history. The Western Ghats is composed of such smaller landscape units. The Anamalai unit where we have been working consistently is considered one among the three biodiversity rich zones of the Western Ghats - Sri Lanka Biodiversity hotspots. The landscape is a mosaic of unique Wet Evergreen Forest formation including the threatened low elevation riparian forest and the coastal evergreen sacred grooves sand dunes, backwater and fresh water canal systems, Screw pine thickets and relics of Mangroves. Each landscape unit in the Western Ghats is a continuum and the river basins within are the subunits. The river and the watersheds ensure longitudinal connectivity."
