Amboseli National Park, formerly Maasai Amboseli Game Reserve, is in Kajiado County, Kenya. The park is 39,206 hectares (392 km2; 151 sq mi) in size at the core of an 8,000 square kilometers (3,100 sq mi) ecosystem that spreads across the Kenya-Tanzania border. The local people are mainly Maasai, but people from other parts of the country have settled there attracted by the successful tourist-driven economy and intensive agriculture along with the system of swamps that makes this low-rainfall area (average 350 mm (14 in)) one of the best wildlife-viewing experiences in the world with 400 species of birds including water birds, pelicans, kingfishers, crakes, hammerkops and 47 types of raptor.
The Rift Valley lakes are a group of lakes in the East African Rift that runs north-south through the eastern side of the African continent, from Ethiopia in the north to Malawi in the south. These lakes include some of the oldest, largest, and deepest lakes in the world. Many are freshwater ecoregions of great biodiversity, while others are alkaline "soda lakes" supporting highly specialized organisms.
