The black rhinoceros is a critically endangered animal. To try to protect the remaining rhinos, some of them have been moved to a new location inside a reserve as part of the WWF’s Black Rhino Range Expansion Project. The rhinos will be safer from poachers in their new location in Limpopo Province.

One new technique involves airlifting 19 rhinoceroses by helicopter after they had been tranquilized! This is a fast and easy way to move the animals to transport vehicles. “It is also so simple a concept that we are all kicking ourselves that we didn’t do it long ago,” said project leader Jacques Flamand.
