Vegetation dynamics of coastal sand dunes near Malindi, Kenya

This study describes the composition, structure and distribution of coastal dune vegetation near Malindi, Kenya. The vegetation was made up of 156 plant species. Sixty families were recorded with Gramineae (seventeen species) and Papilionaceae (sixteen species) being the most widely represented. Fifteen plant communities were described in the different geomorphologic units. The plant communities exhibited a distinct zonal distribution. Halopyrum mucronatum and Ipomoea pes‐caprae plant communities were common in the unstable geomorphologic units. Cordia somaliensis and Pluchea dioscoridis plant communities were common in the more stable geomorphologic units. Most of the plants in the more stable geomorphologic units were shrubs and trees. Succulent herbs were identified in the slacks and the drowned valley, which have moist and damp environments.
