. However, they are not found in rainforests, perhaps in part because of their inability to thermoregulate in hot, humid conditions and the paucity of food in the subcanopy of such forests. Historically, the species had a wider habitat range than the White Rhino, occurring throughout much of sub-Saharan Africa. The species seems almost preadapted to disperse or to recolonize lost range, because it can feed in a variety of habitats and can survive up to five days without drinking. Rhino densities and carrying capacity have been shown to vary widely overits range. Carrying capacity is particularly dependent on the amount of suitable food. Densities can vary widely, from 0-01 ind/km? in poorly vegetated desert plains to peak levels of around 1-5 ind/km?. The carrying capacity in most areas is in the range of 0-1-0-4 ind/km?®. Savannas are dynamic, and changes in woody vegetation result in fluctuations in the carrying capacity of an area. Competition from other browsers can affect the Black Rhino’s use of habitat. The three Asian species are good swimmers and are never found far from water, but Black Rhinos are poor swimmers. They and White Rhinos can drownif they lose their footing.

This species is essentially solitary. Males and females aggregate solely for breeding. Courtship,as in other rhino species,is quite violent. Mating can occur in any time of the year, and as in the Greater One-horned Rhino, shows no seasonal pattern. One exception might be for the south-western subspecies, where births may aggregate in the end of the rainy season when forage is most abundant. Reproductive data are similar to other species: gestation around 15-16 months, intercalf interval of 2-4 years (often depending on range conditions and population density relative to an area’s carrying capacity), and age atfirst reproduction around seven years. Conception rates improve with increases in rainfall. As in other species of rhinos, weaning takes place at around two years of age. Calves generally leave their mothers at around 3-5 years of age, but a female calf may remain with its mother after a new calf is born. Predation by Spotted Hyenas (Crocuta crocuta) and Lions (Panthera leo) on young calves occasionally occurs, and perhaps the oldersister’s remaining with the mother provides added defence against predators, although this has yetto be fully investigated.

Black Rhinos feed in the morning and evening hours. During the hottest part of the day, they remain largely inactive, sleeping, resting, and, where available, wallowing in mud. Most observations of rhinos drinking at waterholes in daylight have been past midday and into the late afternoon. Peak times for drinking are at night.

Black Rhinos are essentially solitary other than when breeding or occasionally when foraging. Studies of social organization reveal a range of behaviors relating to their use of space, from near-territorial to overlapping home ranges. As with other large herbivores, defending a widely distributed food source, such as browse,is difficult and may happen more where food resources are limited and widely spaced, and where females congregate. Differences in forage availability greatly influence home range size. Home ranges can be as large as

1970 and to just under 15,000 only a decade later. The nadir forthis species occurred in the 1980s, when the total population may have dipped below 2400. Today, the speciesis largely restricted to parks and reserves where the rhinos can be better protected. Most of these areas are fenced. Some are small (less than 50,000 ha); others are very large (such as Greater Kruger National Park). Most of the unfenced areas where the rhinos occur are Intensive Protection Zones (IPZs), which were created to give them a higher level of protection. As with the White Rhino, most Black Rhino populations today have been created by translocating surplus animals from long-established populations and biologically managing populations for growth.

. By the start of 2008 the total population had reached 4200 individuals, and the current number may now be in the region of 4800. The decline in Black Rhino populations is largely a result of poaching to obtain the horn, long prized for dagger handles in

and in other nations of the Persian Gulf region. Islamic leaders have declared that rhino horn should not be used for dagger handles, and this has helped to curb this dangerous consumption. The use of rhino horn in traditional Chinese medicine (predominantly as a fever reducer and not as an aphrodisiac) has also caused much poaching. Reports of new medical uses for rhino horn in

and increasing prices being paid for horn are a major cause for concern. Poaching of rhinos in Africa has been increasing in recent years and the growing involvement of organized crime syndicates is of great concern. In areas with both species, the Black Rhino tends to suffer lower levels of poaching, as the White Rhino spends more time in more open areas and is easier to find. As densities have built up in many populations in the major range states, surplus animals have become available for translocation.

, very limited sport hunting of a few specific individual surplus male Black Rhinos is enhancing the likelihood of meeting genetic and demographic goals (e.g. by removing a behaviorally dominant bull thatis infertile) and at the same time generating much needed revenue to help fund conservation efforts. Translocation offers the possibility of establishing populationsin state-run, private, and community-owned reserves. Increased protected areas available for Black Rhinos hold out hope for Black Rhino conservation. Countries, local communities, and individuals can receive substantial income from ecotourism, so the incentive exists to encourage people to protect, monitor, and manage these rare large mammals.

, the Black Rhino Range Expansion Project, with partnerships between the state sector and private or community landowners, allows Black Rhino from source populations in state reserves to be used to found populations on land not necessarily traditionally involved in conservation. This strategy has created five new and viable Black Rhino populations on blocks of land capable of holding at least 50 rhinos, and has increased the land available to Black Rhinos in
