About Aberdare ranges

The Aberdare Range

The Aberdare Range is a significant mountain range located in west-central Kenya, stretching approximately 160 kilometers (99 miles) north to south. It forms a crucial part of the eastern rim of the Great Rift Valley and lies just south of the Equator. The range is known locally among the Agikuyu people as Nyandarua, a name derived from their word for a drying hide, reflecting its distinctive folded silhouette.

Topography and Water Resources

The range features steep western slopes that descend into the Kinangop Plateau and the Great Rift Valley, while its eastern slopes are more gentle. The highest peak is Mount Satima, reaching an elevation of 3,999 meters (13,120 ft). The Aberdare Range is vital for Kenya's water security, serving as a primary water catchment area for the Sasumua and Ndakaini dams, which supply Nairobi with most of its water. Furthermore, the mountain forests are a source for the Tana River, Kenya's largest river, feeding the Seven Forks hydroelectric power complex that generates over half of the country's electricity.

Ecology and Biodiversity

The Aberdare Range supports diverse ecosystems, transitioning from rainforests at lower elevations to dense bamboo forests and then to moorlands at higher altitudes. These varied habitats are home to a rich array of wildlife, including elephants, buffalos, giant forest hogs, hyenas, black rhinos, bongos, and various species of cats such as leopards and the rare African golden cat. Threatened species like the black and white colobus monkey and the endemic Aberdare cisticola also inhabit the range. The Aberdare National Park, established in 1950, protects a significant portion of this natural heritage.

Tourism and Cultural Importance

The Aberdare Range attracts hikers and climbers, with activities often centered around the main towns of Naivasha and Gilgil. The lower slopes are utilized for farming, while the higher areas are known for their wildlife. Historically, the range served as a headquarters for Dedan Kimathi, a leader of the Mau Mau Uprising in the 1950s. It also holds a unique place in modern history as the location where Princess Elizabeth became Queen Elizabeth II while staying at Treetops Hotel.

The range was named in 1884 by explorer Joseph Thomson in honor of Lord Aberdare, who was then president of the Royal Geographical Society and the Royal Historical Society.
