In this video Jim visits the Ngorongoro Crater in the Ngorongoro Conservation Area of Tanzania.

The main feature of the NCA is the Ngorongoro Crater, which is the world's largest unbroken, unflooded volcanic caldera. The Crater, which formed when a giant volcano exploded and collapsed on itself some two to three million years ago, is 610 m (2,001 ft) deep and its floor covers 260 km² (102 square miles). Estimates of the height of the original volcano range from fifteen to nineteen thousand feet (4500 to 5800 metres) high.

Although thought of as "a natural enclosure" for a very wide variety of wildlife, up to 20% or more of the wildebeest (Connochaetes taurinus) and half the zebra (Equus burchelli) populations vacate the Crater in the wet season. However, an effect of this 'enclosure' situation means that the population of Ngorongoro lions is severely inbred, with many genetic problems passed from generation to generation. This is due to the very small amount of new bloodlines that enter the local gene pool, with very few migrating male lions entering the crater from the outside. Animal populations in the crater include most of the species found in East Africa, but there are no impalas (Aepyceros melampus), topis (Damaliscus lunatus), oribis (Ourebia oribi), giraffes (Giraffa camelopardalis), or crocodiles (Crocodylus niloticus).

The crater highlands on the side facing the easterly trade winds receives 8001200mm of rain a year and is covered largely in montane forest, while the less-steep west wall receives only 400600 mm; this side is grassland and bushland dotted with Euphorbia bussei trees. The crater floor is mostly open grassland with two small wooded areas dominated by Acacia xanthophloea.

The Munge Stream drains Olmoti Crater to the north, and is the main water source draining into the seasonal salt lake in the center of the Crater. This lake is known by ... (less info)
