The East African montane moorlands is a montane grasslands and shrublands ecoregion which occupies several high mountain peaks in Kenya, South Sudan, Tanzania, and Uganda.

Contents

Geography

The ecoregion occupies an area of 3,300 square kilometers (1,300 sq mi), covering several small mountaintop enclaves. These include Mount Elgon on the Uganda-Kenya border, The Aberdare Mountains and Mount Kenya in Kenya, and Mount Meru, Mount Kilimanjaro, and Ngorongoro Crater in Tanzania.

The ecoregion occupies areas higher than 3,500 metres (11,500 ft) elevation. Below the montane moorlands is the East African montane forests ecoregion.

Flora

Plant communities include ericaceous woodland and wooded grassland, Dendrosenecio woodland and wooded grassland, tussock grassland, Helichrysum shrub, and swamps or mires. The flora includes many Afroalpine endemic species which are adapted to the harsh conditions. Adaptations include rosette and tussock forms and silvery leaves. From 3500 to 4500 meters elevation plants can grow up to eight meters high, and include giant species of Dendrosenecio and Lobelia. Tussock grasslands are found in dry and fire-prone areas. Helichrysum scrub is found on dry and rocky slopes. Above 4500 meters elevation vegetation is mostly low cushion plants, including Agrostis sclerophylla and Sagina afroalpina, which extend up to the limit of vegetation at around 5000 meters. The East African moorland flora has much in common with that of the Rwenzori-Virunga montane moorlands. [2]

Fauna

The montane moorlands ecoregion shares several limited-range bird species with the lower-elevation East African montane forests. Hunter's cisticola (Cisticola hunteri) is found on all the mountains in the ecoregion. Jackson's francolin (Pternistis jacksoni) and Sharpe's pipit (Macronyx sharpei) is found on Mount Elgon, the Aberdare Range, and Mount Kenya. The Aberdare cisticola (Cisticola aberdare) is found only in the Aberdare Mountains and the Mau Escarpment. [2]

Protected areas

Protected areas in the ecoregion include Aberdare National Park, Aberdare Forest Reserve, Mount Kenya National Park, Mount Kenya Forest Reserve, Mount Elgon National Park, Kilimanjaro National Park, Arusha National Park, and Kipipiri Forest Reserve. [3]

Montane grasslands and shrublands Biome defined by the World Wildlife Fund

Montane grasslands and shrublands is a biome defined by the World Wildlife Fund. The biome includes high altitude grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high altitude", rather than the ecological term which denotes the region below treeline.

Aberdare Range Mountain range in Kenya

The Aberdare Range is a 160 km long mountain range of upland, north of Kenya's capital Nairobi with an average elevation of 3,500 metres (11,480 ft). It is located in Nyandarua County, west central Kenya, northeast of Naivasha and Gilgil and just south of the Equator. The mountain range is called Nyandarua among the Agikuyu people in whose territory this forest and mountain range is located. The name Nyandarua comes from the Kikuyu word rwandarua meaning a drying hide, due to the distinctive fold of its silhouette.

Ethiopian Highlands

The Ethiopian Highlands is a rugged mass of mountains in Ethiopia, situated in northeast part of Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below 1,500 m (4,900 ft), while the summits reach heights of up to 4,550 m (14,930 ft). It is sometimes called the Roof of Africa due to its height and large area. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrea.

<i>Dendrosenecio</i>

Dendrosenecio is a genus of flowering plants in the sunflower family. It is a segregate of Senecio, in which it formed the subgenus Dendrosenecio. Its members, the giant groundsels, are native to the higher altitude zones of ten mountain groups in equatorial East Africa, where they form a conspicuous element of the flora.

Dendrosenecio johnstonii, formerly Senecio johnstonii, is a giant groundsel found in the middle altitudes of Mount Kilimanjaro in Africa. A recent botanical reclassification split off some species formerly in Senecio, putting the giant groundsels in the new genus Dendrosenecio. It also redefined the former species Senecio cottonii, as a subspecies of Dendrosenecio johnstonii. Both genera are in the family Asteraceae. The giant grounsels of the genus Dendrosenecio evolved, about a million years ago, from a Senecio that established itself on Mount Kilimanjaro, with those that survived adapting into Dendrosenecio kilimanjari. As it moved down the mountain, the adaptations necessary for the new environment created the new species, Dendrosenecio johnstonii. Various subspecies are found on other mountains.

Natural history of Mount Kenya

The flora and fauna of Mount Kenya are diverse, due to the variation in altitude, rainfall, aspect and temperature. The mountain slopes can be divided into vegetation zones, with each zone having different dominant plant species. Although many plants on Mount Kenya have local names, here they are reported only with their English and scientific names.
