Item Open Access Ecohydrology of a seasonal wetland in the Rift Valley: ecological characterization of Lake Solai(Blackwell Publishing Ltd, 2009-09-30T00:00:00Z) De Bock, Tanguy; Kervyn De Meerendré, Baptiste; Hess, Tim M.; Gouder De Beauregard, Anne-ChristineThe following research describes through an ecohydrological approach, the first assessment of the ecology of Lake Solai, with a particular emphasis on the vegetation. Lake Solai is located 50 km north of Nakuru in the Rift Valley in Kenya at E36°80′-36°84′ to N00°05′- 00°08′. It is a shallow lake that follows a very peculiar seasonal water regime, and that faces conflicts between agriculture and conservation water users. In the upper catchment, an overview of the agricultural practices was implemented and river water uses were identified to assess river flows. Crops/grassland and woodland/shrubland were the major land uses, covering c. 65% of the catchment. Closer to the lake, vegetation samples were collected around the lake together with samples of environmental factors such as soil and water quality. Thirteen vegetation communities were identified within four main zonations: forest, grassland, river inlet and rocky outcrop. These communities showed abundance, distribution and diversity determined mostly by the human pressures, the flooding periods and the salinity. Cynodon, Cyperus and Sporobolus genera were the most abundant
