The lake has diversified plant and animal life at the production level of the food chain. Rainfall distribution is trimodal with peaks centred around April, August and November giving an average annual total of about 1000mm. Nakuru National park can be traced back to the formation of the Rift Valley and the rocks are volcanic in origin. Soils owe their origin to their parent rock. They are fragile, highly porous with unconsolidated texture susceptible to erosion.
Cliffs characterise west of the lake and are a tourist attraction.
There are over 450 different bird species including palaeartic migrant and about 56 different Mammal species. As a result, fish eating birds came in. The fish is in direct competition with the Lesser flamingo feeding on the Blue -green algae. Rhinos were first introduced in 1987, the same time the park was declared a Rhino sanctuary. Both black and white rhinos total over 75.
