about is born. Births usually peak in the dry season, and take place in thickets – unlike the wildebeest, which give birth in groups on the plains. Though calves can move about on their own shortly after birth, they usually lie in the open in close proximity of their mothers. The calf is weaned at four months, but young males stay with their mothers for two and a half years, longer than in other Alcelaphini. Often the mortality rate of male juveniles is high, as they have to face the aggression of territorial adult males and are also deprived of good forage by them. The lifespan is 12 to 15 years. Habitat Hartebeest inhabit dry savannas, open plains and wooded grasslands, often moving into more arid places after rainfall. They are more tolerant of wooded areas than other Alcelaphini, and are often found on the edge of woodlands. They have been reported from altitudes on Mount Kenya up to . The red hartebeest is known to move across large areas, and females roam home ranges of over , with male territories in size. Females in the Nairobi National Park (Kenya) have individual home ranges stretching over , which are not particularly associated with any one female group. Average female home ranges are large enough to include 20 to 30 male territories. Status and conservation Each hartebeest subspecies is listed under a different conservation status by the International Union for Conservation of Nature. The species as a whole is classified as Least Concern by the IUCN. The hartebeest is extinct in Algeria, Egypt, Lesotho, Libya, Morocco, Somalia, and Tunisia. The Bubal hartebeest has been declared extinct since 1994. German explorer Heinrich Barth, in his works of 1857, cites firearms and European intrusion among the reasons for the decrease in its numbers. It was extinct in Tunisia by the late 19th century. The last individual was shot in Missour (Algeria) in 1925. Coke's hartebeest is listed as Least Concern. This species has been greatly affected by habitat destruction, and about 42,000 Coke's hartebeest occur today in Mara, Serengeti National Park, and Tarangire National Park in Tanzania and Tsavo East National Park in Kenya. The population is decreasing, and 70% of the population lives in protected areas. The Lelwel hartebeest is listed as Endangered, and numbers have declined greatly since the 1980s, when its population was over 285,000. It was formerly distributed mainly
