The Rann of Kutch is a large area of salt marshes that span the border between India and Pakistan. It 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 was left behind, which explains why the Luni does not flow into the Arabian Sea today.
Geography
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
Many rivers originating in
, 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 bets or medaks, which lie two to three metres above flood level. Trees and shrubs grow on the bets, and they provide refuges for wildlife during the annual floods.[1]
Climate
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.[1]
Rainfall is highly seasonal. The Rann of Kutch is dry for most of the year, and rainfall is concentrated in 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.[1]
Ecology

Flora
The predominant vegetation in the Rann of Kutch is grassland and thorn scrub. Common grass species include
Trees are rare except on 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.[1]
Fauna
The Rann of Kutch is home to about 50 species of mammals. They include several large herbivores, including
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).[1]
History and culture
The history of the Rann of Kutch began with early
Indus Valley period
The people of the Indus civilization appear to have settled in the Rann of Kutch around 3500 BCE.[7] The Indus city of Dholavira, the largest Indus site in India, is located in the Rann of Kutch. This city was built on the Tropic of Cancer, possibly indicating that Dholavira's inhabitants were skilled in astronomy.[8] The Rann of Kutch also contained the industrial site of Khirasara, where a warehouse was found.[9]
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 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.[10]
Imperial Indian Period
The Rann of Kutch was a part of both the Maurya[11] and Gupta[12] empires of India.
Colonial and Modern periods
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
Conservation and protected areas
A 2017 assessment found that 20,946 km2, or 76%, of the ecoregion is in protected areas.[2] They include the Kutch Desert Wildlife Sanctuary (7506.22 km2), which was established in 1986 and covers much of the Great Rann, and the Indian Wild Ass Sanctuary (4953.71 km2), which was established in 1973 and covers much of the Little Rann.[15] Pakistan's Rann of Kutch Wildlife Sanctuary protects the northern portion of the Great Rann and adjacent Thar Desert.
