The blackrhino is quite rare today this is because the African habitat has changed and the rhinoceros need s certain requirements to live happily and breed successfully. To start with they need a large area of water this is for them to drink but they also like to bathe in the water so it needs to be a reasonable size pool of fresh water that can be replenished.
Secondly, the rhino is a big African animal and it needs lots of grass and shrubs to graze on day after day and week after week. There also needs to be enough shade for them so they can escape the hot sun and rest during the day. The last thing is they like to coat their bodies in mud because the mud has minerals in the help to nourish their skin. It also adds as a kind of protection against the hot sun during the day.
So they have to relocate to a suitable shrub land that has water and can sustain their appetite.
These African animals are solitary, the stay by themselves most of the time only coming together for breeding and little else. One calf is usually born after 15months and the mother looks after it for a year and after that they have little to do with each other.
