Description

The Indian wild ass, as with most other Asian wild ass subspecies, is quite different from the African species
African Wild Ass
The African Wild Ass is a wild member of the horse family, Equidae. This species is believed to be the ancestor of the domestic donkey which is usually placed within the same species. They live in the deserts and other arid areas of northeastern Africa, in Eritrea, Ethiopia and Somalia; it...

. The coat is usually sandy, but varies from reddish grey, fawn, to pale chestnut. The animal possesses an erect, dark mane which runs from the back of the head and along the neck. The mane is then followed by a dark brown stripe running along the back, to the root of the tail.

Range extension in recent years

It seems to be increasing in numbers and extending its range from Little Rann of Kutch, where the world's last population of this subspecies had got confined to in recent years, and has gradually started moving out and colonizing Greater Rann of Kutch also extending into the neighboring Indian State of Rajasthan in the bordering villages in Jalore district bordering the Rann of Kutch in Gujarat. Gujarat’s supposed monopoly over this sub-species, also referred to as Khur (Equus hemionus khur) has thus been broken. Within Rajasthan it has started making its presence felt in Khejariali and its neighbourhood where a 60 km2 area was transferred to the Rajasthan Forest Department by the revenue authorities in 2007. At this place Rebaris (camel and sheep breeders) live in the Prosopis juliflora

pods, and saline vegetation. It is one of the fastest of Indian animals, with speeds clocked at about 70 – 80 km. per hour and can easily outrun a jeep. Stallions live either solitarily, or in small groups of twos and threes while family herds remain large. Mating season is in rainy season. When a mare comes into heat, she separates from the herd with a stallion who battles against rivals for her possession. After few days, the pair returns to the herd. The mare gives birth to one foal. The male foal weans away by 1–2 years of age, while the female continues to stay with the family herd.

Need to Re-establish populations

In the last century, the Indian wild ass lived all over the dry regions of northwestern India and western Pakistan including Jaisalmer, Bikaner, Sind and Baluchistan. Today, it survives only in the Little Rann, and a few stray towards the Great Rann of Kutch with some reaching bordering villages in the Jalore district of the Indian State of Rajasthan

. First census of the wild ass was done in 1940, when there were an estimated 3,500 wild asses. But, by the year 1960, this figure fell to just 362, it was then classified as a highly endangered species. In the years 1973 & 1976, Rann of Kutch and adjoining districts were taken up as the area for conservation for this sub-species also known as Khur. From 1976, the forest department began conducting the Wild Ass census. Water holes were increased in the area, the forest department has also started a project for having fodder plots though the forest department is yet to get desired success. In 1998, Wild Ass population was estimated at 2,940, by the year 2004 it has increased to an estimated 3,863. A recent census conducted by forest department in 2009 has revealed that the population of wild ass in the state was now estimated to about 4,038, an increase of 4.53% as compared to 2004. Of late it has been spotted right outside Ahmedabad

. It seems it is no more confined to the 4,953.71 km2 area of the Rann, but it is now being found right up to the Kala Dungar near Banni grasslands in Kutch and Nal Sarovar. Within the State of Gujarat it is now also found in districts of Surendranagar, Rajkot, Patan, Banaskantha and Kutch. This population of wild ass is the only gene pool of Indian Wild Ass (Khur) in the entire world and one of the six geographical varieties or sub-species surviving on the planet.

The population has been growing since 1976 but the wild ass experts warn, long-term trends show intense fluctuations. This area in Kutch, Gujarat is drought-prone due to erratic monsoon

s, the wild ass population could decline suddenly as a result of a massive die-off. It is only if there are no severe droughts, the species is likely to grow and disperse in the Great Rann and adjoining Rajasthan, habitats that the wild ass occupied in the recent past.
