Brief synthesisThe Kenya Lake System is composed of three alkaline lakes and their surrounding territories: Lake Bogoria, 10,700 ha; Lake Nakuru, 18,800 ha; and Lake Elementaita, 2,534 ha. These lakes are found on the floor of the Great Rift Valley where major tectonic and/or volcanic events have shaped a distinctive landscape. Criterion (ix): The Kenya Lake System illustrates ongoing ecological and biological processes which provide valuable insights into the evolution and the development of soda lake ecosystems and the related communities of plants and animals. Criterion (x): The Kenya Lake System is the single most important foraging site for the Lesser Flamingo in the world with about 1.5 million individuals moving from one lake to the other and provides the main nesting and breeding grounds for Great White Pelicans in the Great Rift Valley. IntegrityThe three lakes constituting the property represent the most significant Rift Valley lakes within Kenya, and are an essential component of those in the Great Rift Valley as a whole.
