Serengeti National Park is undoubtedly the best-known wildlife sanctuary in the world, unequalled for its natural beauty and scientific value, it has the greatest concentration of plains game in Africa.The Serengeti National Park in Tanzania was established in 1952. It is home to the greatest wildlife spectacle on earth - the great migration of wildebeest and zebra. The resident population of lion, cheetah, elephant, giraffe, and birds is also impressive. There’s a wide variety of accommodation available, from luxury lodges to mobile camps. The park covers 5,700 sq miles, (14,763 sq km), it’s larger than Connecticut, with at most a couple hundred vehicles driving around.The Park can be divided into 3 sections. The popular southern/central part (Seronera Valley), is what the Maasai called the “serengit”, the land of endless plains. It’s classic savannah, dotted with acacias and filled with wildlife. The western corridor is marked by the Grumeti River, and has more forests and dense bush. The north, Lobo area, meets up with Kenya’s Masai Mara Reserve, is the least visited section.Two World Heritage Sites and two Biosphere Reserves have been established within the 30,000 km² region. It’s unique ecosystem has inspired writers from Ernest Hemingway to Peter Mattheissen, filmakers like Hugo von Lawick and Alan Root as well as numerous photographers and scientists - many of which have put their works at our disposal to create this website.The Serengeti ecosystem is one of the oldest on earth. The essential features of climate, vegetation and fauna have barely changed in the past million years. Early man himself made an appearance in Olduvai Gorge about two million years ago. Some patterns of life, death, adaptation and migration are as old as the hills themselves.
Each year around the same time, the circular great wildebeest migration begins in the Ngorongoro Conservation Area of the southern Serengeti in Tanzania and loops clockwise through the Serengeti National Park and north towards the Masai Mara reserve in Kenya.This migration is naturally caused, by the availability of grazing. The initial phase lasts from about January to March, when the calving season begins – a time when there is plenty of rain-ripened grass available for the 260,000 zebras that precede 1.7 million wildebeest and the following hundreds of thousands of other plains game, including around 470,000 gazelles.
During February, the wildebeest are on the short grass plains of the southeast part of the ecosystem, grazing and giving birth to approximately 500,000 calves in 2 to 3 weeks. Few calves are born ahead of time and of these, hardly any survive, largely because very young calves are more noticeable to predators when mixed with older calves from the previous year. As the rains end in May, the animals start moving northwest into the areas around the Grumeti River, where they typically remain until late June. The crossings of the Grumeti and Mara rivers beginning in July are a popular safari attraction because crocodiles are lying in wait.The herds arrive in Kenya in late July / August, where they stay for the rest of the dry season, except that the Thomson's and Grant's gazelles move only east/west. In early November, with the start of the short rains, the migration starts moving south again, to the short grass plains of the southeast, usually arriving in December in plenty of time for calving in February.
About 250,000 wildebeest die during the journey from Tanzania to the Maasai Mara National Reserve in southwestern Kenya, a total of 800 kilometres (500 mi). Death is usually from thirst, hunger, exhaustion, or predation including by big cats.
