Lake Magadi is a soda lake located in the Rift Valley that is highly alkaline from dissolved sodium and carbonate, recharged by saline hot springs. There is a large resident lesser flamingo population that feed on the cyanobacteria and algae. The landscape of these lakes is changing, affecting the flamingo populations. There has been more rainfall and that has diluted the salinity of the soda ash lakes which the flamingos depend on to survive. Declines in healthy soda lake ecosystems threaten their unique biodiversity.
