The environment has all the resources rhinos naturally use, including plenty of year-round grazing, sandy areas for resting and rolling, mud wallow, and shade trees along with rocks and tree trunks for rubbing against. Our rhinos have access to a specially designed house, adjacent landscaped hardstanding area with water hole and a large paddock shared with scimitar-horned oryx and Grevy’s zebra. Born in 2017, Zahra is Marwell’s youngest rhino, and she is also the newest rhino to join the group, arriving in 2021 from Safari Zoo Cumbria. Pembe was also born in 2013, and she arrived here from Colchester Zoo in 2016. ![]() He was born in 2013 so will soon be mature and hopefully ready to breed. Our male white rhino Jabari arrived from Dublin Zoo in 2015. Our oldest rhino, Kiri, was born in 1986, arriving at Marwell in 1988 from Whipsnade Zoo. There have been white rhino at Marwell since 1986 and we currently have four animals. Intensive monitoring and protection of white rhinos from poaching is critical to their survival while animals may be translocated between areas to manage and safeguard their populations. Increasing interest from criminal syndicates involved in the illegal trade in rhino horn poses a significant threat. These are used in traditional medicine and ornaments, primarily in South East Asia. However, the species remains at risk from illegal hunting (poaching) for their horns. Recent estimates suggest that there may now be around 18,000 individual white rhinos. Populations have also been established in Kenya, Uganda and Zambia. However, protection and translocation (capturing and transporting) of animals led to their recovery in South Africa and being reintroduced to Botswana, Eswatini, Namibia, and Zimbabwe. The Southern white rhino was almost hunted to extinction by the end of the 19 th Century with only one small population of approximately 20 – 50 animals remaining in KwaZulu-Natal, South Africa. ![]() Only two individuals of this sub-species remain, both female, now living at the Ol Pejeta Conservancyin Kenya. The Northern white rhino is thought to be extinct across its entire former range. Calves remain with their mothers for around 3 years, eventually separating when a new calf is born. Calves normally move in front of their mothers, begin grazing after a few weeks and weaning occurs around 1 year of age. Following a 16-month gestation period, calves are born and able to stand within an hour, immediately trying to suckle. Male white rhinos may be 10 years old before they are ready to breed, whereas females mature around 6 or 7 years old and then may have a calf every 3 years. ![]() White rhinos use a surprisingly wide range of vocal communication including contact calls, grunts and snorts, plus higher pitched squeals when distressed, and deep bellows signifying aggression or when threatened. The odour reveals information about age, sex, the territorial status of males and whether females are receptive to breeding. This affords protection but while young rhino calves may be vulnerable to lions Panthera leo and spotted hyaenas Crocuta Crocuta, older animals are generally untroubled by predators.īoth male and female white rhinos advertise their presence using communal dung heaps known as middens. Females and their offspring may congregate in herds of up to a dozen or so animals. Dominant male white rhinos are solitary and territorial but may tolerate the presence of subordinate males.
