Site description An area of natural landscape at the grassland-forest boundary, only 7 km from the centre of Kenya’s capital city, Nairobi. The park’s varied habitats include open, rolling grass plains, riverine woodland, valley thicket and bush, artificial dams and ponds, rocky gorges and upland dry forest. The park is fenced along three sides, where it is adjacent to urban housing, industry, roads and airports; only the southern border, along the Embakasi and Athi rivers, is open for animal dispersal. Ecologically, the park is intimately linked to the Kitengela and Athi-Kapiti plains, which adjoin it to the south, forming a single ecological unit. Being close to the city centre and supporting a variety of large mammals, this park is a popular destination and a substantial money-earner for the Kenya Wildlife Service.

Other biodiversity Nairobi National Park has healthy populations of an array of large mammals. The park is a rhino sanctuary and numbers of Diceros bicornis (CR) are steadily increasing. Acinonyx jubatus (VU) also occur in good numbers. Several plants growing on the rocky hillsides are unique to the Nairobi area, including Euphorbia brevitorta, Drimia calcarata, Murdannia clarkeana and an undescribed Crassula sp. The park protects an important area of Croton–Brachylaena–Calodendron upland dry forest. This distinctive Nairobi forest-type exists now only as small, ever diminishing fragments.
