Description
East African lionesses in Ngorongoro Conservation Area, Tanzania.
The lion (Panthera leo) is a species in the Felidae family and a member of the genus Panthera. It has been listed as Vulnerable on the IUCN Red List since 1996, as populations in African range countries declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes of concern. The West African lion population is listed as Critically Endangered since 2016.
The lion typically inhabits grasslands and savannahs, but is absent in dense forest. It is usually more diurnal than other big cats, but when persecuted adapts to being active at night and at twilight. A lion pride consists of a few adult males, related females and cubs. Prides vary in size and composition from three to 20 adult lions, depending on habitat and prey availability. Females cooperate when hunting and prey mostly on large ungulates. They are opportunistic hunters and prefer prey weighing 190 to 550 kg (420 to 1,210 lb). The lion is an apex and keystone predator.
Females form the stable social unit in a pride and do not tolerate outside females. Membership only changes with the births and deaths of lionesses, although some females do leave and become nomadic. Although extremely large prides, consisting of up over 30 individuals, have been observed, the average pride consists of around fifteen lions; including several adult females, up to four males (known as a coalition if more than one) and their cubs of both sexes.
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 main feature of the Ngorongoro Conservation Authority is the Ngorongoro Crater, the world's largest inactive, intact and unfilled volcanic caldera. The crater, which formed when a large volcano exploded and collapsed on itself two to three million years ago, is 610 metres (2,000 feet) deep and its floor covers 260 square kilometres (100 square miles). Estimates of the height of the original volcano range from 4,500 to 5,800 metres (14,800 to 19,000 feet) high. The elevation of the crater floor is 1,800 metres (5,900 feet) above sea level. The Crater was voted by Seven Natural Wonders as one of the Seven Natural Wonders of Africa in Arusha, Tanzania in February 2013.
The volcanic eruptions like that of Ngorongoro, which resulted in the formation of Ngorongoro Crater in Tanzania, were very common. Similar collapses occurred in the case of Olmoti and Empakaai, but they were much smaller in magnitude and impact. (Description from Wikipedia)
