Impacts of the past exploitation and inappropriate management are the main factors that need to be addressed for the conservation of ecosystems. Planting trees generally seems like a good solution but planting unsuitable trees can lead to degradation of ecosystems. Hence the ecorestoration requires detailed micro level information on plant compositions in various heterogeneous environments across our landscapes. We have collated a wide range of information on heterogeneous species composition especially of riparian forest, forest ecosystems, sacred groves, coastal ecosystems and threatened species habitats in various bioclimates of the Southern Western Ghats. Data gathered in the past two decades helped us to develop an ecorestoration protocol or prioritization of species composition of ecorestoration without impacting on niches of other species. A combination of Niche modelling and Niche profiling has been used as a methodology for prioritization. We were able to initiate some studies towards planning for ecorestoration and initiated ecorestoration programmes in degraded forest fragments, disaster hit areas, threatened species habitats, sacred groves and coastal regions.
