Site description This area comprises a very shallow, strongly alkaline lake (3,300 ha), with surrounding woodland and grassland. Set in a picturesque landscape, the park abuts Nakuru town, an important and expanding agricultural and industrial centre. The lake catchment is bounded by Menengai Crater to the north, the Bahati Hills to the north-east, the Lion Hill ranges to the east, Eburu Crater to the south and the Mau escarpment to the west. Three major rivers, the Njoro, Makalia and Enderit, drain into the lake, together with treated water from the town’s sewage works and the outflow from several springs along the shore. Nakuru was first gazetted as a bird sanctuary in 1960 and upgraded to National Park status in 1968. A northern extension to the park was added in 1974. The foundation of the lake’s simple food chains is the cyanophyte Spirulina platensis, which often occurs as a unialgal bloom. At such times it can support huge numbers of Phoenicopterus minors and the fish Oreochromis alcalicus grahami (introduced in 1960 from Lake Magadi, IBA KE047, to curb mosquitoes). The fish in turn support a number of secondary consumers. The lakeshores are mainly open alkaline mud, with areas of sedge Cyperus laevigatus and Typha marsh around the river inflows and springs, giving way to grassland and a belt of Acacia xanthophloea woodland. Rocky hillsides on the park’s eastern perimeter are covered with Tarchonanthus scrub and magnificent Euphorbia forest.
