Terai Arc Landscape & Tiger Corridors

That's Dudhwa my agent pointed out to me. What!Where!" All I could see were some sugar cane fields and grassy patches. Not until we cut through a dense canopy of Sal did I realize that we were at the periphery of Dudhwa Tiger Reserve.  

This was, way back few years a ago. The tiger reserve is now home to Rhino after a successful translocation. The reserve is host to the Northern Swamp deer, tigers, hispid hare, pygmy hog, wild elephants, and a number of mammals besides a large number of bird species. The region holds some rare and endangered species.     

Swamp deer was in abundance in the old time but due to excess hunting and habitat destruction, their population is limited to the tiger reserve. Singhai township is one place I frequently visited, this was once a hunting ground near the tiger reserve, and the name addresses the swamp deer. Singhai means an assemblage of horns this is in reference to the rare swamp deer species. Maharajahs and the British favored this place for hunts. Rest is the sordid saga of the destruction of wilderness in India.     

The North or Uttar Pradesh is a land of plains and intense agriculture. Heavily populated and urbanized, Dudhwa and adjoining forest patches are the few that are left. Thankfully they are under much-needed protection as wildlife sanctuaries and tiger reserves,

Dudhwa now encompasses Kishanpur Wildlife Sanctuary and is connected to Pilibhit Tiger Reserve and Katarniaghat Wildlife Sanctuary through narrow corridors - weak and facing human intrusion. On the Nepal side, the forest contiguity is provided by Shukla Phanta Wildlife Sanctuary and Bardia National Park.       

The green corridors connect the wildlife heavens but are in much need of protection and care. The corridors are denuded in place but nevertheless, animals migrate to adjoining forests in times of stress.

A green corridor that connects Dudhwa with Shuklaphanta is  Laldhadi. The lagga-Bagga corridor connects Pilibhit to Shuklaphanta. The Kartaniaghat-Khata and Boom-Brahmadev Corridors to Shuklaphanta and Nandhaur Wildlife Sanctuary. The latter is in the Uttarakhand State of India. Bardia National Park in Nepal is connected with Katarniaghat through the Khata Green Corridor. Rhinos migrate to and fro through this corridor.    

Human settlements engulf and intrude on the corridors reducing connectivity and giving rise to frequent man-animal conflicts. Many years ago the region had become volatile due to frequent cases of man-eating, especially at Gola and Mohammadi townships in Lakhimpur Kheri District where Dudhwa TR and Kisanpur WLS are situated. 

Man-animal conflicts do occur in recent times but the frequency has decreased thanks to greater surveillance and conservation measures.  A lot of work is being done to repair and rejuvenate these vital passages which have resulted in some improvement. The beleaguered wilderness needs much more work to be done if the free movement of wild animals has to take place without stress.

Apart from afforestation, resource preservation including water and strict protection management has to be in place if the tiger population in Terai Arc Landscape has to bounce back. This region had a one-time abundant tiger population and a high density of prey base. The resulting denudation has had an adverse impact on the floral characteristic. Human population and land use dynamics in the present circumstances have a negative impact on the habitats resulting in fragmentation and affecting the viability of corridors used for migration. Understanding key factors that impact habitats and life forms that inhabit the ecosystems is vital for the conservation ecology of the region as a whole.
