The head and body are massive, and a pronounced bump (nuchal hump) on top of its short neck helps support the head. In silhouette, the sacral bump two thirds of the way along the back is much more marked than in the Black Rhino, which tends to have a more curved back profile. The most dramatic features aside from the enormoussize are the large horns and distinct square lip. The anterior horn is normally the larger of the two, and averages

. The horns of females are often longer and thinner than those of males, which tend to be shorter and chunkier. The extremely wide mouth is unlike that of other rhinos and lacks the prehensile tip found in other species. Skin color varies from a brownish wash to gray. Body hair is limited to the tips of the ear and tail. The ear shape also differs from that of a Black Rhino.

Both the northern and southern subspecies are grazers, so are restricted to grassland and savanna habitats. They also fare poorly in areas subjected to very cold, frosty winters or in very arid areas. The highest densities occur in savannas where soils are reasonably nutrient rich and rainfall levels are intermediate (around 700-800 mm), such as in Hluhluwe-Umfolozi Game Reserve (2-3 ind/km?) in

In contrast to the African Black Rhino, the White Rhino is strictly a grazer. The specialized mouth parts—a broad flat lower lip and hard pad—are adaptations for a grazing lifestyle and allow the White Rhino to clip grasses close to the ground. The efficiency with which rhinos graze creates what ecologists term “grazing lawns,” which are also used by other wild herbivores attracted to the nutritious regrowth and to the open areas where predators are more easily detected.

Reproductive data are similar to other rhino species. Gestation is 16 months, intercalf interval is 2-3 years on good grazing grounds, and age at first reproduction is about 6-7 years. As with other species, courtship is aggressive and the males pursue females, trying to keep estrous females within their breeding territories.

The large mass of the White Rhino implies that it must devote a considerable amount of time to feeding to meetits metabolic requirements. White Rhinos spend about half the day grazing, interspersed with resting periods (often on breezy ridge tops or under trees) and wallowing in muddy depressions during the hottest hours of the day. White Rhinos drink daily but can go for several days without drinking.

), subadult males may cluster, perhaps to avoid being driven off by dominant males and to gain better access to the best grazing areas. Dominant bulls mark their home ranges by daily patrols of their boundaries, spraying urine, depositing dung in latrines, and making prominent scrapes on the ground. In Garamba National Park, animals ranged over several hundred square kilometers. In south-west Kruger the average range of adult males was 9-9 km*and females 22.8 km? The summer wet season range of females was larger, 21-4 km* compared to 11-6 km? for males. In the Hluhluwe-Umfolozi Game Reserve, core areas for territorial males averaged only 1-7 km?in prime habitat and the average size of female ranges was lower than in Kruger, at 16-2 km®. Dominant bulls try to retain females in estrus that wander through their territories, so the males compete for the home ranges with the best water and grazing, which are mostlikely to attract females. White Rhinos, unlike the Asian rhinos, are poor swimmers and sometimes drown, which explains why major rivers, such as the

This remarkable effort shows that even very large, slow-reproducing mammals can recover relatively quickly if provided strict protection, enough space, good forage conditions, and active biological management where surplus animals have been translocated to set up new populations. Southern White Rhinos can be bought and sold, and since 1968 there has also been limited sport hunting. This has helped create economic incentivesfor the private sector and more recently for local communities to conserve White Rhinos, and has generated much-needed revenue to help fund their conservation. The successful translocation programs for the Southern White Rhino have inspired similar efforts with the Greater One-horned Rhino in

By then, the number had been reduced to only 15, but under protection the number increased to 30 by 1992.

in the hope that this will stimulate successful breeding. Given the low founder genome equivalent of these “pure” Northern White Rhinos (which are interrelated), conservation biologists have recommended intercrossing these animals with Southern White Rhinos. The hope now lies in conserving as many adaptive Northern White Rhino genesas possible, and eventually, if this is successful, reintroducing animals with these genes into the species’ former range, or, failing that, into suitable secure areas nearits former range.
