Why this rhino in Kenya is protected round the clock by armed rangers

The photo above shows a male northern white rhino being protected by armed men in conservation in Kenya.
The Grindtv.com reports that “the world’s population of northern white rhinos is down to five and the Ol Pejeta Conservancy is home to three of them, including the last remaining male—which is being guarded by armed rangers around the clock.”

The report says that “along with the critically endangered northern white rhinos, the conservancy in Kenya is also home to 23 white rhinos and 105 black rhinos, making it the largest black rhino sanctuaries in East Africa.”
