Qurna Marshes

The Central or Qurna Marshes are a large complex of wetlands in Iraq that, along with the Hawizeh Marshes (Iraq/Iran), Hawizeh and Hammar Marshes, Hammar marshes, make up the Mesopotamian Marshes of the Tigris–Euphrates river system. Formerly covering an area of around 3000 square kilometres, they were Draining of the Qurna Marshes, almost completely drained following the 1991 uprisings in Iraq and have in recent years been reflooded.

Characteristics

The Central Marshes stretched between Nasiriyah, Ezra's Tomb, Al-'Uzair (Ezra's Tomb) and Al-Qurnah and were mainly fed by the Tigris and its distributaries (the Shatt al-Muminah and Majar al-Kabir). They were drained by the (partially artificial) Prosperity Canal, and by the Glory River. The Central Marshes were characterised by tall ''qasab'' Phragmites, reeds but included a number of freshwater lakes, of which the largest were the Haur az-Zikri and Umm al Binni lake, Umm al-Binni (literally "mother of ''binni''", the latter being a species of Barbel (fish), barbel.)The Physical Characteristics of the Mesopotamian Marshlands

The area was formerly populated by the Marsh Arabs or Ma'dan, who grazed Domestic buffalo, buffalo on the natural vegetation and carried out cultivation of rice.

Draining

By the early 1980s, it was evident that irrigation projects were already affecting water levels in the marshes.Spencer, M
''The Marsh Arabs Revisited
''Saudi Aramco World'', April 1982 In the early 1990s, the government of Iraq undertook a series of major drainage projects, at least partly in retribution for the events of the 1991 uprisings, and to prevent the area being used as a refuge by militias. The flow southwards from the distributary streams of the Tigris was blocked by large embankments and discharged into the Al-Amarah or Glory Canal, resulting in the loss of two-thirds of the Central Marshes by as early as 1993. A further canal, the Prosperity Canal, was constructed to prevent any overflow into the marsh from the main channel of the Tigris as it ran southwards from Qalat Saleh.The Physical Characteristics of the Mesopotamian Marshlands
edenagain.org By the late 1990s, the Central Marsh had become completely desiccated, suffering the most severe damage of the three main areas of wetland. By 2000, United Nations Environment Programme estimated that 90% of the marshlands had disappeared.

Reflooding

Following the 2003 U.S. invasion of Iraq, embankments and drainage works were broken open, and the marshes began to reflood. The Central Marshes showed little recovery through 2003, but by early 2004 a patchwork of lakes had appeared in northern areas; there was flooding in southern areas which had previously been dry since the early 1990s.Iraq Marshlands Restoration Program
iraqmarshes.org, p.6 There has been some corresponding recolonisation by the natural marsh vegetation since that time, and return of some species of fish and birds, although recovery of the Central Marshes has been much slower compared to the Huwaizah and Hammar Marshes; the most severely damaged sections of the wetlands have yet to show any signs of regeneration.Missan Governorate Assessment Report
UNHCR, 2006, p.44 Bunn's short-tailed bandicoot rat is suspected to have become extinct.
