The Rift Valley's Lake Natron is the chosen mating ground of the endangered lesser flamingo. Analysis of lake features in the imagery, including the presence of salt islands, has been used to set lower and upper limits to lake areas suitable for flamingo breeding. Comparison to infrequent observations of flamingo breeding at Natron are consistent with the prevailing hypothesis of the importance of receding lake levels. #Flamingo natron lake seriesA time series of lake surface area has been produced which shows a high degree of variability in lake levels. In addition, local environmental change and global climate change over the past 50 years have altered the hydrological characteristics of the catchment.Īrchival Landsat imagery (1984–2011) has been used to establish baseline data about the past hydrological variability of the lake by applying the Modified Normalised Difference Water Index (MNDWI). Both developments will significantly alter the hydrology and ecology of the lake and could impact flamingo breeding. Lake Natron is threatened by two proposed developments: a multi-purpose dam, to be built on the Ewaso Ngiro (South) River (45% of the lake's catchment area), and a soda ash extraction factory. The lake is of critical importance as the sole breeding site for East Africa's population of Lesser Flamingos ( Phoeniconaias minor), a species which is classified as near-threatened due to decreasing numbers and limited suitable breeding sites (IUCN). Other volcanoes usually spew silicates, but the Ol Doinyo Lengai is the only one on the planet that spills "natrocarbonatites" as cool, runny, dark washes.Landsat satellite imagery was used to investigate the ecohydrological sustainability of Tanzania's Lake Natron. A courting pair, plump from gulping down. It's a favorite among petrologists because it's the only one of its kind, Hannes Mattsson, a researcher at the Swiss Institute of Technology in Zurich, told NBC News. Life and death on the banks of Lake Natron Flamingo flocks arrive at Natron annually, even though each bird will mate only once every four or five years. The culprit is Ol Doinyo Lengai, a million-year old volcano just south of Lake Natron.

The "salt" in it isn't the regular table variety harvested from seawater, but magmatic limestone that's been forged deep in the Earth, poured out in runny lava flows and blasted into the air to become ash clouds 10 miles high. Water levels fluctuate easily because it's so hot - when the levels drop, the corpses are left behind on the shores, coated in salt, exactly how Brandt found them. ![]() Due to the rare chemical composition, the lake ends up petrifying the animals that enter it. But appearances can be deceiving: its waters hold a fatal secret. Small birds or bats that try and fail to cross the 12- by 30-mile lake fall in, as do insects like beetles and locusts. Petrified flamingo in the lake Lake Natron, situated in northern Tanzania, close to the Kenyan border, in the Great Rift Valley, is one of the most peaceful places in Africa. 28th Feb 2016 Report inappropriate content simbalionboss Nairobi, Kenya 3 posts 8. Fact Check: Lake Natron in Tanzania is a saltwater lake with a pH of 10. Nick Brandt / Courtesy of Hasted Kraeutler Gallery Because the quantity of water of the lake increased, the flamingo can not make their nest. Crimson Wing is a documentary based on the lives of some flamingo chicks throughout their birth to young adulthood Filmed mainly around Lake Natron in. Flamingos are some of the lucky birds that can make the trip across the lake which is 30-miles wide at its longest point. "If a body falls anywhere else it decomposes very quickly, but on the edge of the lake, it just gets encrusted in salt and stays forever," David Harper, an ecologist at the University of Leicester who has visited Lake Natron four times, told NBC News. ![]()
