Almost exterminated by poachers, the black rhino is still in serious danger of extinction. Stocks worldwide are reckoned to be around 2,000. The last few black rhino live outside national parks in Namibia. Swarovski Optik is supporting national protection and surveillance programmes there. The game wardens there now use night-vision instruments, telescopes and binoculars made in the Tyrol. The company has also provided support by creating watering holes.
