Flamingos prefer mud sites for nesting, but soda ash extraction would deepen the lake and flood these sites, making them unusable. Freshwater sources and the lake water itself would also become heavily polluted with domestic and industrial waste, sewage and toxic chemical seepage from storage areas. These effluents could significantly lower the salinity of the lake and increase its turbidity, lowering the productivity of cyanobacteria such that the lake would support fewer flamingos. 2007).Ĭovering a wide area and including new road, rail and air links, a coal-fired power station and modern housing, the facility is predicted to extract more than 100,000 litres of freshwater and 550,000 litres of brine from the lake every hour and to pump back over 400 metric tons of depleted brine and 90 metric tons of mud. In 2007, plans were unveiled to build a soda (sodium carbonate) extraction facility on the shores of the lake, a proposition that would significantly change its hydrology and chemical composition rendering it unsuitable for Lesser Flamingo (Fishpool and Evans 2001, Burton et al. Indeed it is the only known site in East Africa where the species regularly nests, with 2.5 million individuals (75 % of the global population) flocking to the area every year (Koenig 2006, BirdLife International 2008).
With vast isolated salt flats providing safety from predators and ready supplies of freshwater and food from lakeside springs and cyanobacteria-rich hot saline waters, Lake Natron is a perfect breeding site for Lesser Flamingo Phoeniconaias minor, classified as Near Threatened on the 2008 IUCN Red List.
It is internationally recognised as a valuable wetland site by the Ramsar Convention and as an Important Bird Area (IBA) by BirdLife International (Fishpool and Evans 2001, TME 2007).
Lake Natron in Tanzania is an important wildlife area that supports a thriving Masai community and large mammal and bird populations.
