Ladakh - Flora and Fauna

Flora and Fauna

The wildlife of this region was first studied by Ferdinand Stoliczka, an Austrian-Czech palaeontologist, who carried out a massive expedition in the region in the 1870s. Vegetation is extremely sparse in Ladakh except along streambeds and wetlands, on high slopes, and in irrigated places.

The fauna of Ladakh has much in common with that of Central Asia in general and that of the Tibetan Plateau in particular. Exceptions to this are the birds, many of which migrate from the warmer parts of India to spend the summer in Ladakh. For such an arid area, Ladakh has a great diversity of birds — a total of 225 species have been recorded. Many species of finches, robins, redstarts (like the Black Redstart), and the Hoopoe are common in summer. The Brown-headed Gull is seen in summer on the river Indus and on some lakes of the Changthang. Resident water-birds include the Brahminy duck also known as the Ruddy Sheldrake and the Bar-headed Goose. The Black-necked Crane, a rare species found scattered in the Tibetan plateau, is also found in parts of Ladakh. Other birds include the Raven, Red-billed Chough, Tibetan Snowcock, and Chukar. The Lammergeier and the Golden Eagle are common raptors here.

The Bharal or "blue sheep" is the most abundant mountain ungulate in the Ladakh region. However it is not found in some parts of Zangskar and Sham areas. The Asiatic Ibex is a very elegant mountain goat that is distributed in the western part of Ladakh. It is the second most abundant mountain ungulate in the region with a population of about 6000 individuals. It is adapted to rugged areas where it easily climbs when threatened. The Ladakhi Urial is another unique mountain sheep that inhabits the mountains of Ladakh. The population is declining, however, and presently there are not more 3000 individuals left in Ladakh. The urial is endemic to Ladakh, where it is distributed only along two major river valleys: the Indus and Shayok. The animal is often persecuted by farmers whose crops are allegedly damaged by it. Its population declined precipitously in the last century due to indiscriminate shooting by hunters along the Leh-Srinagar highway. The Tibetan argali or Nyan is the largest wild sheep in the world, standing 3.5 to 4 feet at the shoulder with the horn measuring 90–100 cm. It is distributed on the Tibetan plateau and its marginal mountains encompassing a total area of 2.5 million km2. There is only a small population of about 400 animals in Ladakh. The animal prefers open and rolling terrain as it runs, unlike wild goats that climb into steep cliffs, to escape from predators. The endangered Tibetan Antelope, commonly known as chiru, or Ladakhi tsos, has traditionally been hunted for its wool (shahtoosh) which is a natural fiber of the finest quality and thus valued for its light weight and warmth and as a status symbol. The wool of chiru must be pulled out by hand, a process done after the animal is killed. The fiber is smuggled into Kashmir and woven into exquisite shawls by Kashmiri workers. Ladakh is also home to the Tibetan gazelle, which inhabits the vast rangelands in eastern Ladakh bordering Tibet.

The kiang, or Tibetan wild ass, is common in the grasslands of Changthang, numbering about 2,500 individuals. These animals are in conflict with the nomadic people of Changthang who hold the Kiang responsible for pasture degradation. There are about 200 snow leopards in Ladakh of an estimated 7,000 worldwide. The Hemis High Altitude National Park in central Ladakh is an especially good habitat for this predator as it has abundant prey populations. The Eurasian lynx, is another rare cat that preys on smaller herbivores in Ladakh. It is mostly found in Nubra, Changthang and Zangskar. The Pallas's cat, which looks somewhat like a house cat, is very rare in Ladakh and not much is known about the species. The Tibetan Wolf, which sometimes preys on the livestock of the Ladakhis, is the most persecuted amongst the predators. There are also a few brown bears in the Suru valley and the area around Dras. The Tibetan Sand Fox has recently been discovered in this region. Among smaller animals, marmots, hares, and several types of pika and vole are common.

Scant precipitation makes Ladakh a high-altitude desert with extremely scarce vegetation over most of its area. Natural vegetation mainly occurs along water courses and on high altitude areas that receive more snow and cooler summer temperatures. Human settlements, however, are richly vegetated due to irrigation.

Natural vegetation commonly seen along water courses includes seabuckthorn (Hippophae spp.), wild roses of pink or yellow varieties, tamarisk (Myricaria spp.), caraway, stinging nettles, mint, Physochlaina praealta, and various grasses.

Natural vegetation in unirrigated desert around Leh includes capers (Capparis spinosa), Nepeta floccosa, globe thistle (Echinops cornigerus), Ephedra gerardiana, rhubarb, Tanacetum spp., several artemisias, Peganum harmala, and several other succulents. Juniper trees grow wild in some locations and are usually considered sacred by Buddhists.

Human settlements are marked by lush fields and trees, all irrigated with water from glacial streams, springs, and rivers. Higher altitude villages grow barley, peas, and vegetables, and have one species of willow (called Drokchang in Ladakhi). Lower villages also grow wheat, alfalfa, mustard for oil, grapes, and a greater variety of vegetables. Cultivated trees in lower villages include apricots, apples, mulberries, walnuts, Simon poplars, Afghan poplars, oleaster (Elaeagnus angustifolia), and several species of willow (difficult to identify, and local names vary). Elms and white poplars are found in the Nubra Valley, and one legendary specimen of white poplar grows in Alchi in the Indus Valley. Black Locust (Robinia Pseudoacacia), Himalayan Cypress and horse chestnut have been introduced since the 1990s.
