Palaeoecology Modern ecology Based on the latest checklists of biodiversity at Lake Urmia in 2014 and 2016, it is home to 62 species of
archaebacteria and
bacteria, 42 species of
microfungi, 20 species of
phytoplankton, 311 species of plants, five species of
mollusca, 226 species of birds, 27 species of amphibians and reptiles and 24 species of mammals (47 fossils have been recorded in the area). Lake Urmia is an internationally registered protected area as both a
UNESCO Biosphere Reserve The
Iranian Department of Environment has designated most of the lake as a national park. A recent drought has significantly decreased the annual amount of water the lake receives. This in turn has increased the salinity of the lake's water, reducing its viability as home to thousands of migratory birds, including
flamingo populations. The salinity has particularly increased in the half of the lake north of the
Urmia Lake Bridge. By virtue of its high
salinity, the lake no longer sustains any fish species. Nonetheless, Urmia Lake is considered a significant natural habitat of
Artemia, which serve as food source for the migratory birds such as
flamingos. In early 2013, the then-head of the Iranian Artemia Research Center was quoted that
Artemia urmiana had gone extinct due to the drastic increases in salinity. However this assessment has been contradicted, and another population of this species has recently been discovered in the
Koyashskoye Salt Lake at the
Crimean Peninsula.
Falling level and increasing salinity The lake is a major barrier between
Urmia and
Tabriz, two of the most important cities in the provinces of
East Azerbaijan and
West Azerbaijan. A project to build a highway across the lake was initiated in the 1970s but was abandoned after the
Iranian Revolution of 1979, leaving a causeway with an unbridged gap. The project was revived in the early 2000s, and was completed in November 2008 with the opening of the
Urmia Lake Bridge across the remaining gap. The highly saline environment is already heavily rusting the steel on the bridge despite anti-corrosion treatment. Experts have warned that the construction of the causeway and bridge, together with a series of ecological factors, will eventually lead to the drying up of the lake, turning it into a salt marsh, which will adversely affect the climate of the region. Lake Urmia has been shrinking for a long time, with an annual evaporation rate of . Although measures are now being taken to reverse the trend, the lake has shrunk by 60% and could disappear entirely. On 2 August 2012,
Mohammad-Javad Mohammadizadeh, the head of Iran's Environment Protection Organization, announced that
Armenia had agreed to transfer water to counter the critical fall in Lake Urmia's water level, remarking that "hot weather and a lack of precipitation have brought the lake to its lowest water levels ever recorded". He added that recovery plans for the lake included the transfer of water from Eastern Azerbaijan Province. Previously, Iranian authorities had announced a plan to transfer water from the
Aras River, which borders Iran and
Azerbaijan, but the 950-billion-
toman plan was abandoned due to Azerbaijan's objections. In July 2014, Iran President
Hassan Rouhani approved plans for a 14 trillion rial program (over $500 million) in the first year of a recovery plan. The money was supposed to be used for water management, reducing farmers' water use, and environmental restoration. Several months earlier, in March 2014, Iran's Department of Environment and the United Nations Development Programme (UNDP) issued a plan to save the lake and the nearby wetland, which called for spending $225 million in the first year and $1.3 billion overall for restoration. Starting in 2016, Food and Agriculture Organization of the United Nations (FAO) and Urmia Lake Restoration Program (ULRP) signed up to a project funded by the Government of Japan entitled "An Integrated Programme for Sustainable Water Resources Management in the Lake Urmia Basin" to support ULRP in its goal to restore Lake Urmia. The project set out a multi-disciplinary framework covering several key interrelated areas and aims to have five outputs: 1. An advanced water accounting (WA) system for the entire Lake Urmia basin; 2. A drought management system based on risk/vulnerability assessment and preparedness response for the basin; 3. A socio-economic livelihood programme with viable and sustainable alternatives to current agricultural activities upstream of the lake to reduce water consumption significantly while maintaining the income and livelihood of affected communities; 4. An integrated watershed management (WM) programme; A capacity development programme to strengthen stakeholders at different levels. The
Silveh Dam in
Piranshahr County should be complete in 2015. Through a tunnel and canals it will transfer up to of water annually from the Lavin River in the
Little Zab basin to Lake Urmia basin. In 2015, president Hassan Rouhani's cabinet approved $660 million for improving irrigation systems, and steps to combat desertification. By the end of the summer of 2025, the lake had completely disappeared according to
NASA images.
Environmental protests The prospect that Lake Urmia might dry up entirely has drawn protests in Iran and abroad, directed at both the regional and national governments. Protests flared in late August 2011 after the Iranian parliament voted not to provide funds to channel water from the
Aras River to raise the lake level. Apparently, parliament proposed instead to relocate people living around Urmia Lake. Further demonstrations took place in the streets of
Tabriz and
Urmia on 27 August and 3 September 2011. Amateur video from these events showed riot police on motorcycles attacking apparently peaceful protesters. According to the governor of
West Azerbaijan, at least 60 supporters of the lake were arrested in Urmia, and dozens in Tabriz, because they had not applied for a permit to organize a demonstration. The effect of climate change on the lake, has been extensively covered by an Iranian photojournalist
Solmaz Daryani. ==Islands==
