40-400: A lake or pond . This happens in climates where the rate of water evaporation exceeds the rate of precipitation — that is, in a desert. If the water cannot drain into the ground, it remains on the surface until it evaporates, leaving behind minerals precipitated from the salt ions dissolved in the water. Over thousands of years , the minerals (usually salts) accumulate on

80-587: A well-known salt pan in the arid regions of the western United States . The Etosha pan , in the Etosha National Park in Namibia , is another prominent example of a salt pan. The Salar de Uyuni in Bolivia is the largest salt pan in the world. As of 2024, with an estimated 23 million tons , Bolivia holds about 22% of the world's known lithium resources (105 million tons); most of those are in
100-514: A wider distribution but is now limited to the Rann of Kutch. The nilgai and blackbuck are threatened species. There are over 200 bird species in the Rann of Kutch, including the threatened species lesser florican ( Sypheotides indicus ) and houbara bustard ( Chlamydotis undulata ). The seasonal wetlands provide habitat for many water birds, including the demoiselle crane ( Grus virgo ) and lesser flamingo ( Phoeniconaias minor ). The history of

Salt pan (geology) Natural salt pans or salt flats are flat expanses of ground covered with salt and other minerals , usually shining white under the sun . They are found in deserts and are natural formations (unlike salt evaporation ponds , which are artificial). A salt pan forms by evaporation of a water pool, such as
140-726: Is located mostly in the Kutch district of the Indian state of Gujarat , with a minor portion extending into the Sindh province of Pakistan . It is divided into the Great Rann and Little Rann . It used to be a part of the Arabian Sea, but it then dried up, leaving behind the salt, which formed the Rann of Kutch. The Luni flowed into the Rann of Kutch, but when the Rann dried up, the Luni
160-625: Is the larger portion of the Rann. It extends east and west, with the Thar Desert to the north and the low hills of Kutch to the south. The Indus River Delta lies to the west in southern Pakistan. The Little Rann of Kutch lies southeast of the Great Rann, and extends southwards to the Gulf of Kutch. Many rivers originating in Rajasthan and Gujarat flow into the Rann of Kutch, including
180-630: The Luni , Bhuki , Bharud , Nara , Kharod , Banas , Saraswati , Rupen , Bambhan, and Machchhu . Kori Creek and Sir Creek , tidal creeks which are part of the Indus River Delta, are located at the western end of the Great Rann. The surface is generally flat and very close to sea level, and most of the Rann floods annually during the monsoon season. There are areas of sandy higher ground, known as bet s or medak s, which lie two to three metres above flood level. Trees and shrubs grow on
200-547: The Tropic of Cancer , possibly indicating that Dholavira's inhabitants were skilled in astronomy. The Rann of Kutch also contained the industrial site of Khirasara , where a warehouse was found. Many Indologists such as A. S. Gaur and Mani Murali hold the view that the Rann of Kutch was, rather than the salt marsh that it is today, a navigable archipelago at the time of the Indus Civilization. The Indus Civilization
220-513: The June to September monsoon season. During the monsoon season, local rainfall and river runoff flood much of the Rann to a depth of 0.5 metres. The waters evaporate during the long dry season, leaving the Rann dry again by the start of the next monsoon season. The Rann of Kutch is the only large flooded grasslands zone in the Indomalayan realm . The area has desert on one side and the sea on

#1732772468780240-592: The Rann of Kutch began with early neolithic settlements. It was later inhabited by the Indus Valley Civilization as well as the Maurya Empire and Gupta Empire of India . The people of the Indus Civilization appear to have settled in the Rann of Kutch around 3500 BCE. The Indus city of Dholavira , the largest Indus site in India, is located in the Rann of Kutch. This city was built on
260-477: The Salar de Uyuni. The large area, clear skies, and exceptional flatness of the surface make the Salar an ideal object for calibrating the altimeters of Earth observation satellites. Parts of Rann of Kutch (India) are salt marsh in the wet season and salt pan in the dry season. Rann of Kutch The Rann of Kutch is a large area of salt marshes that span the border between India and Pakistan. It
280-629: The bets which rise above the flood zone. The non-native tree Prosopis juliflora has become established on the bets, and its seed pods provide year-round food for the wild asses. The Rann of Kutch is home to about 50 species of mammals. They include several large herbivores, including Indian wild ass ( Equus hemionus khur ), chinkara ( Gazella bennettii ), nilgai ( Boselaphus tragocamelus ), and blackbuck ( Antilope cervicapra ), and large predators like wolf ( Canis lupus ), striped hyena ( Hyaena hyaena ), desert wildcat ( Felis lybica ), and caracal ( Felis caracal ). The Indian wild ass once had
300-411: The bets, and they provide refuges for wildlife during the annual floods. The climate of the ecoregion is tropical savanna/semi-arid. Temperatures average 44 °C during the hot summer months, and can reach highs of 50 °C. During winter the temperature can drop to or below freezing point. Rainfall is highly seasonal. The Rann of Kutch is dry for most of the year, and rainfall is concentrated in
320-528: The other, which enables various ecosystems, including mangroves and desert vegetation . Its grassland and deserts are home to forms of wildlife that have adapted to its often harsh conditions. These include endemic and endangered animal and plant species. The predominant vegetation in the Rann of Kutch is grassland and thorn scrub. Common grass species include Apluda aristata , Cenchrus spp., Pennisetum spp., Cymbopogon spp., Eragrostis spp., and Elionurus spp. Trees are rare except on
340-625: The residents of the Rann of Kutch began holding the Rann Utsav festival, a three-month long carnival, which marks the peak tourist season. Kadiya dhro in Nakhatrana is a popular place amongst tourists. A 2017 assessment found that 20,946 km , or 76%, of the ecoregion is in protected areas. They include the Kutch Desert Wildlife Sanctuary (7506.22 km ), which was established in 1986 and covers much of
360-473: The surface. These minerals reflect the sun's rays and often appear as white areas. Salt pans can be dangerous. The crust of salt can conceal a quagmire of mud that can engulf a truck. The Qattara Depression in the eastern Sahara Desert contains many such traps which served as strategic barriers during World War II . The Bonneville Salt Flats in Utah , where many land speed records have been set, are
380-533: Was known to have an extensive maritime trade system, so it has been proposed by Gaur et al. that there were perhaps ports in the Rann of Kutch. The Rann of Kutch was a part of both the Maurya and Gupta empires of India. The Rann of Kutch came under the control of the British Raj, who imposed a ban on salt harvesting. This ban was protested and overturned by Indian activist Mahatma Gandhi . More recently,
400-588: Was left behind, which explains why the Luni does not flow into the Arabian Sea today. The Rann of Kutch is located mostly in the Indian state of Gujarat , specifically Kutch district , for which it is named. Some parts extend into the Pakistani province of Sindh . The word Rann means "desert" in Gujarati. The Rann of Kutch covers around 26,000 square kilometres (10,000 square miles). The Great Rann of Kutch
