Grasslands larger than life

The Meadows

Unique feature of the tiger reserves of Central India are the grasslands that lie interspersed between rugged mountains and enchanting valleys. Also known as boheras in Bandhavgarh and maidan in Kanha these are hub of activities in the ecosystem.

The grasslands or meadows are the center of attraction for man animals and birds alike. The tourist flock these meadows in order to see the tiger and the deer. Since the thick canopy obstructs wildlife sighting the tourist jeeps prefer to move around the grasslands in order to see the tigers.

Tigers love the tall grasses of the prairies and sulk in between to ambush prey. They love the cover of the tall grass and the shade. In Bandhavgarh tiger reserve the Boheras are marshy and have proven to be excellent hunting grounds for the tigers. The slush hinders fast movement of the deer and the big cats find it easy to pounce upon them.

In Kanha the meadows besides supporting the tigers are home to critically endangered Swamp Deer. This is the only hard ground Barasingha population left in the wild. The deer now survives in good enough numbers after it was brought back from brink of extinction. The swamp deer subsists only on certain species of grass and poses conservation challenge to park authorities.

The grasses are frequented not only by tigers and deer they are home to many species of birds and reptiles. With luck one can see the reticulated python or other snakes. Most often seen grass birds are plain prinia, jungle prinia, zitting cisticola, warblers, common stonechat, pipits and larks, francolins painted and grey, munias or avadavat, storks and many others.

In order to stalk prey tigers frequent these grassy maidans. Since the concentration of deer is very high hunting is much easier. In the open spaces movement is not hampered like in thick canopy. They are easily camouflaged in the dry grass and can hide easily. Hence spotting tigers in grasslands is not as easy as people presume.

The most popular grasslands in Bandhavgarh are Chur Bohera, Raj bohera, bathan and chakradhara. Similarly the Kanha meadow is most popular, preferred by animals and tourists alike. Others are Saunf meadow where Swamp Deer breed, Kisli meadow and Parsa tola to name a few.

Most of the grasslands are small in area whence compared with Dhikala Chuad in Corbett Tiger Reserve. The height is much less than elephant grass. Most of the grasslands in Central Indian Tiger Reserves in MP are edaphic. They were earlier settlements which have been trans located elsewhere. The vacated fields have been overtaken by local species of grass and secondary scrub.

The savannas are always under threat from fire and over grazing. Thankfully live stock is not allowed inside the core area and the park authorities are constantly guarding the habitats from fires. The predators maintain the right population of deer hence prevent overgrazing. A major challenge being faced by conservation team in Kanha emanates from the lendia tree. This tree is slowly encroaching into the grasslands and reducing them. The swamp deer depend entirely on these ecosystems hence to stop the encroachment or leave nature to take care of things is a difficult decision to be taken.

Besides habitats of many species in these National Parks the savannas are vital to the ecosystem. They constitute major support system to these diverse habitats and have tremendous water retention capacity.

Tigers in the grasslands

Large extensive edaphic grasslands are typical to many of our tiger reserves. Earlier inhabited by local tribesmen these precious habitats were vacated for the subsistence of wild species to whom the habitat belonged for eons. The grasslands are prime habitats for deer species, especially for animals like the swamp deer. Swamp deer survive solely on marshy grasslands in India. The swamp deer or Barasingha at Kanha is an exception as it has adapted to an existence on hard ground. The grassy meadows are at the fulcrum of activities in our tiger reserves.

Most of the prey and predator saga unfolds here - the grassland is a vital element of the food chain. Bandhavgarh is a prime example of a grassland ecosystem interspersed with dense Sal forests. Many of the grasslands inhabited by tribesmen have been vacated. Inundated by rivulets, the wet marshy grasslands are preferred hunting grounds for the majestic tigers. Bandhavgarh though small is a prolific breeding ground for Bengal tigers. The undulating terrain, inaccessibility, dense canopy, and large prey base is the reason. The survival rate of the cubs is very high in this picturesque animal kingdom. The tall grass act as effective camouflage and hence allows the tigers to creep close to the prey before striking. 

Unlike lions, tigers cannot run for a long distance hence they hunt by ambush. The marshy grasslands are effective killing grounds and the big cats love them. They are excellent for raring cubs in absolute safety and shelter. The grassland ecosystem is frequented by a large number of herbivores and hence are ideal prey base. The most powerful of the tiger's reign over these habitats. The meadows are also frequented by territorial females and young males. The struggle for survival means the fittest should exist. Prime grasslands in BTR are Chur Behera, Raj Behera, Chakradhara, Bathan, Sehra, and Mahman. High fecundity, low mortality, and abundant prey make the preserve an ideal tiger habitat with the highest density. For this reason, tiger sightings in the wild are very high. The jungle roads intersect prime tiger habitats in order to accord high visibility to these magical cats. The tourism infrastructure is well-developed. 

A large number of wildlife resorts are available for stay in Bandhavgarh. One can avail of the best packages for accommodation. For safari, jeeps can be hired at Tala village or arranged by the hotels. The tiger reserve is well protected though danger looms all over. Bandhavgarh nature preserve in India is the best place to see tigers in the wild. Every year thousands from all over the World visit the park.

Grasslands of Kanha

Much talked about its tigers, Kanha National Park is an ecosystem that harbors vivid diversity of life forms. It is a true biodiversity conservation center. The topography of the park is unique with rising Maikal Hills enveloped by a dense forest of Sal and Bamboo at places interspersed with grassy meadows, lakes, and small rivers. Unlike Pench, Kanha and Bandhavgarh have less of mixed forest zones. Sal and Bamboo are prevalent in most of the forested zones of the park.

Kanha is famous for not only tigers but its magnificent fauna which boasts twenty-two species. The mouse deer was recently sighted here though earlier reports were not confirmed. The most visible elements of faunal diversity are the herbivores - the main prey base of tigers, leopards, and wild dogs.

Kanha National Park - Meadows

The grasslands of Kanha are extensive and many in number. They are a habitat for a number of grass species like themeda triandra, Sachrum munja, and Bothriocloa odrata to name a few. These grass species are crucial to the survival of herbivores especially the Hard Ground Barasinga or the Hard Ground Swamp Deer (Cervus duavcelli branderi).

Most of the grasslands are edaphic, they were in a much-declined state due to human settlements there. The water logging of soil prevented the growth of perennial woody plants but the grasses grew well. There have been miraculous improvements in the health of these grasslands after the villages were relocated out of Kanha National Park.

The most popular grasslands or meadows in Kanha are the Kanha meadow, Saunf which is the breeding ground of Barsinghas, meadows at Parsa Tola, Kisli, Supkhar, Bamani Dadar, and many more. The grasslands bordering Saundhar Taloa and Bisanpura Talao (Wetlands) are habitats favored by the Barasingha. The Chital or spotted deer are ubiquitous, while Sambar deer are nocturnal and shy. The bison are coarse feeders but climb down the hills to feed in the grasslands in summer.

The meadows are an integral part of the Kanha landscape apart from being a habitat for many life forms including herbivores - the main prey base of the tigers in India. The grassy meadows add charm and enchantment to Kanha's landscape and make it picturesque - as the park is.

The health of grasslands in Kanha is vital for the survival of prey species. Though there is no danger from humans now, the intrusion of lyndia trees is a source of worry for park managers. The ecotone harbors lots of Lyndia tree which are slowly intruding into the meadows. Should there be human intervention or should nature take its own course???
