Biodiversity of desert

 

Stretches of sand in the desert are interspersed by hillocks and sandy and gravel plains. Due to the diversified habitat, the vegetation and animal life in this arid region is very rich. About 23 species of lizard and 25 species of snakes are found here and several of them are endemic to the region.
Some wildlife species, which are fast vanishing in other parts of India, are found in the desert in large numbers such as the great Indian bustard, the black buck, the Indian gazelle, and the wild ass in the Rann of Kutch. How these animals and insects survive in these harsh conditions, under such high temperature and without drinking water and green vegetation are amazing. They have evolved excellent survival strategies, their size is smaller than other similar animals living in different conditions, and they are mainly nocturnal. There are certain other factors responsible for the survival of these animals in the desert. Due to the lack of water in this region, transformation of the grasslands into cropland has been very slow. The protection provided to them by a local community, the Bishnois is also a factor.

The Desert National Park, Jodhpur, spread over an area of 3162 sq.km, is an excellent example of the ecosystem of the Thar Desert, and its diverse fauna. Great Indian bustard, black buck, chinkara, desert fox, Bengal fox, wolf, desert cat etc. can be easily seen here. Seashells and massive fossilized tree trunks in this park record the geological history of the desert. The region is a haven for migratory and resident birds of the desert. One can see many eagles, harriers, falcons, buzzards, kestrel and vultures. Short- toed eagles, tawny eagles, spotted eagles, lagger falcons and kestrels are the commonest of these.

Tal Chhapar Sanctuary is a very small sanctuary in district Churu, 210 km from Jaipur, in the Shekhawati region. This sanctuary is home to a large population of graceful black buck. Desert fox and desert cat can also be spotted along with typical avifauna such as partridge and sand grouse.
