Tarangire National Park is the sixth largest national park in Tanzania, it is located in Manyara Region. The name of the park originates from the Tarangire River that crosses the park. The Tarangire River is the primary source of fresh water for wild animals in the Tarangire Ecosystem during the annual dry season. The Tarangire Ecosystem is defined by the long-distance migration of wildebeest and zebras. During the dry season thousands of animals concentrate in Tarangire National Park from the surrounding wet-season dispersal and calving areas.
It covers an area of approximately 2,850 square kilometers (1,100 square miles.) The landscape is composed of granitic ridges, river valley, and swamps. Vegetation is a mix of Acacia woodland, Commiphora-Combretum woodland, seasonally flooded grassland, and Baobab trees.
The Ngorongoro Conservation Area (NCA) is a protected area and a World Heritage Site located 180 km (110 mi) west of Arusha in the Crater Highlands area of Tanzania. The area is named after Ngorongoro Crater, a large volcanic caldera within the area. The conservation area is administered by the Ngorongoro Conservation Area Authority, an arm of the Tanzanian government, and its boundaries follow the boundary of the Ngorongoro Division of the Arusha Region.
The 2009 Ngorogoro Wildlife Conservation Act placed new restrictions on human settlement and subsistence farming in the Crater, displacing Maasai pastoralists, most of whom had been relocated to Ngorongoro from their ancestral lands to the north when the British colonial government established Serengeti National Park in 1959. The construction of luxury tourist hotels in the Conservation Area allows people to access "the unparalleled beauty of one of the world’s most unchanged wildlife sanctuaries", according to a government brochure, even as thousands of Maasai have suffered forcible eviction and have been denied access to water sources for their livestock
Lake Manyara National Park is a Tanzanian national park located both in Arusha Region and Manyara Region, Tanzania. The two administrative regions have no jurisdiction over the parks. The park is governed by the Tanzania National Parks Authority. The majority of the land area of the park is a narrow strip running between the Gregory Rift wall to the west and Lake Manyara, an alkaline or soda-lake, to the east.
The park consists of 330 km2 (130 sq mi) of arid land, forest, and a soda-lake which covers as much as 200 km2 (77 sq mi) of land during the wet season but is nearly nonexistent during the dry season.
