MOUNT KENYA
At 5,199 m, Mount Kenya is the second highest peak in Africa. It is an ancient extinct volcano, which during its period of activity (3.1-2.6 million years ago) is thought to have risen to 6,500 m. There are 12 remnant glaciers on the mountain, all receding rapidly, and four secondary peaks that sit at the head of the U-shaped glacial valleys. With its rugged glacier-clad summits and forested middle slopes, Mount Kenya is one of the most impressive landscapes in East Africa. The evolution and ecology of its afro-alpine flora provide an outstanding example of ecological and biological processes. Through the Lewa Wildlife Conservancy and Ngare Ndare Forest Reserve, the property also incorporates lower lying scenic foothills and arid habitats of high biodiversity, situated in the ecological transition zone between the mountain ecosystem and the semi-arid savanna grasslands. The area also lies within the traditional migrating route of the African elephant population.
The evolution and ecology of the afro-alpine flora of Mount Kenya provides an outstanding example of ecological processes in this type of environment. Vegetation varies with altitude and rainfall and the property supports a rich alpine and subalpine flora. Juniperus procera and Podocarpus species are predominant in the drier parts of the lower zone (below 2,500 m asl). Cassipourea malosana predominates in wetter areas to the south-west and north-east. Higher altitudes (2,500-3,000 m) are dominated by bamboo and Podocarpus milanjianus. Above 3,000 m, the alpine zone offers a diversity of ecosystems including grassy glades, moorlands, tussock grasslands and sedges. Continuous vegetation stops at about 4,500 m although isolated vascular plants have been found at over 5,000 m.
In the lower forest and bamboo zone mammals include giant forest hog, tree hyrax, white-tailed mongoose, elephant, black rhinoceros, suni, black-fronted duiker and leopard. Moorland mammals include the localized Mount Kenya mouse shrew, hyrax and common duiker. The endemic mole-rat is common throughout the northern slopes and the Hinder Valley at elevations up to 4,000 m. Lewa Wildlife Conservancy and Ngare Ndare Forest Reserve enhance the species diversity within the property including being home to the largest resident population of Grevys’ Zebra in the world. An impressive array of birdlife includes green ibis (local Mount Kenya race); Ayres hawk eagle; Abyssinian long-eared owl; scaly francolin; Rüppell’s robin-chat; numerous sunbirds (Nectariniidae); the locally threatened scarce swift; and near endemic alpine swift.
The Lewa Wildlife Conservancy and Ngare Ndare Forest Reserve component of the property incorporates lower lying, scenic foothills and arid habitats of high biological richness and diversity. The component lies at the ecological transition zone between the Afro Tropical Mountain ecosystem and the semi-arid East African Savannah Grasslands. Lewa Wildlife Conservancy and Ngare Ndare Forest Reserve also lie within the traditional migration route of the African elephant population of the Mount Kenya – Somali/Maasai ecosystem and has always been the traditional dry season feeding area for elephants.
