The Ngorongoro Conservation Area or NCA is a
conservation area situated 180 km (112 miles) west of Arusha in
the Crater Highlands area of Tanzania. 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 Ngorongoro District. It
covers an area of 8,288 km˛ (3,200 square miles) - about the
size of Crete.
History and geography
Based on fossil evidence found at the
Olduvai Gorge, it is known that various hominid species have
occupied the area for 3 million years. Hunter gatherers were
replaced by pastorialists a few thousand years ago. The Mbulu
came to the area about 2,000 years ago, and were joined by the
Datoga around the year 1700. Both groups were driven from the
area by the Maasai in the 1800s. Massive fig trees in the
northwest of the Lerai Forest are sacred to the Maasai and
Datoga people. Some of them may have been planted on the grave
of a Datago leader who died in battle with the Maasai around
1840.
No Europeans are known to have set foot in the
Crater until 1892, when it was visited
by Dr. Oscar Baumann. Two German brothers farmed in the Crater
until the outbreak of World War I, after leasing the land from
the German colonial administration then in control of East
Africa. Dr. Baumann shot three rhinos while camped in the
crater, and the German brothers regularly organized shooting
parties to entertain their German friends. They also attempted
to drive the wildebeest herds out of the crater.
The Ngorongoro area originally was part of the
Serengeti National Park when it was
created by the British in 1951. Maasai continued to live in the
newly created park until 1959, when repeated conflicts with park
authorities over land use led the British to evict them to the
newly declared Ngorongoro Conservation Area.
Land in the conservation area is multi-use, it is unique in
Tanzania as the only conservation area providing protection
status for wildlife whilst allowing human habitation. As such
land use is controlled to prevent negative effects on the
wildlife population, for example cultivation is prohibited at
all but subsistence levels.
The area is part of the Serengeti ecosystem, and to the
north-west, it adjoins the Serengeti National Park and is
contiguous with the southern Serengeti plains, these plains also
extend to the north into unprotected Loliondo division and are
kept open to wildlife through trans-human pastoralism practiced
by Maasai. The south and west of the area are volcanic
highlands, including the famous Ngorongoro
Crater and the lesser known Empakai. The southern and
eastern boundaries are approximately defined by the rim of the
Great Rift Valley wall, which also prevents animal migration in
these directions.
The Maasai people had been grazing their livestock in the open
plains which they knew as “endless plain” for over 200 years
when the first European explorers visited the area. The name
Serengeti is an approximation of the word used by the Maasai to
describe the area. German geographer and explorer Dr. Oscar
Baumann entered the area in 1892. Baumann killed three
rhinos during a stay in the Ngorongoro crater.
The Serengeti is Tanzania's oldest national park and remains the
flagship of the country’s tourism industry, providing a major
draw to the “Northern Safari Circuit”, encompassing Lake Manyara,
Tarangire and Arusha national parks, as well as Ngorongoro
Conservation Area.
Wildlife
A population of approximately 25,000 large animals, largely
ungulates along with reputedly the highest density of mammalian
predators in Africa, lives in the crater. These include the
black rhinoceros, whose local population declined from about 108
in 1964-66 to between 11-14 in 1995, and the hippopotamus, which
is very uncommon in the area. There also are many other
ungulates: the wildebeest (7,000 estimated in 1994), the zebra
(4,000), the eland, and Grant's and Thomson's gazelles (3,000).
