The regal Black Rhino is a rare species these days. Extinct in some parts of the world, recent efforts to save this colossal creature are beginning to show promise in others. Black Rhino populations in Zimbabwe have recovered from a low point of only 370 in 1993 to around 500 animals today. It’s a slow process - but one well worthwhile.

At one time, around 100 species of rhinos roamed the earth. Today, only five remain and all are among the planet's most at-risk species.
