Nature is reestablishing in several parts of Kerala State. Otters have made a comeback to the mangroves in the Asramam area of Ashtamudi Lake in Kollam district. Nilgiri tahr and tigers are sighted in forest areas where they had not been seen for long. Sholas are re-establishing in upper Palani plateau of the Western Ghats not far from Munnar. Several plants in lower elevations too are on a comeback trail. Tribals of Wayanad have harvested more honey this year suggesting that the statuses of the systems that support bees are apparently improving.
The Nilgiri tahrs, protected in Eravikulam National Park, have re-established themselves on hilltops near Lockhart Gap and Adimali outside the sanctuary area in recent years. There are increasing numbers of tahrs in the Mukkurthi National Park in Tamil Nadu. Near viable populations have been reported from a location near Ponmudi in Thiruvanathapuram district at an elevation of about 900 metres.
(Tahrs have also been reported from Parambikulam Wildlife Sanctuary and Silent Valley National Park and more than a dozen other locations in Kerala. Many locations in the Nilgiris, Pulneys and Anamalais of Tamil Nadu also have populations of Nilgiri tahr. Srivilliputhur Grizzled Squirrel Wildlife Sanctuary, Indira Gandhi Wildlife Sanctuary and Kalakkad Mundanthurai Tiger Reserve in Tamil Nadu are among the habitats of the tahr. They inhabit mountain slopes at altitudes ranging from 600 metres to 2600 metres.)
All these point to the fact that many species and ecosystems are resilient enough to make a comeback if adequate protection is accorded. However, the gains achieved in recent years could get reversed on account of climate change or laxity in protection.
