South Africa has the highest concentration of black and white rhinos in Africa. They also have the highest rate of poaching. Beverly Joubert/Rhinos Without Borders
In 2013, over 1,000 rhinos were killed for their horns. Beverly Joubert/Rhinos Without Borders
In Eastern Asia, rhino horn is (inaccurately) believed to cure a range of maladies, from cancer to fever. It is also sold as an aphrodisiac. The horns sell for as much as $65,000 a kilogram on the black market. Beverly Joubert/Rhinos Without Borders
There are only 5,000 black rhinos left on the continent (a 96% reduction since 1970). The white rhino story is a happier tale. Rescued from the brink of extinction, the species now numbers 20,000 -- though conservationists worry they too are in danger, as rhino horn continues to sell for a hefty sum on the black market.

One of the reason's Botswana's poaching level is so low is its zero tolerance for poachers. Anti-poaching is handled by the Botswana Defense Force, who have a "shoot to kill" policy, meaning if a poacher doesn't immediately put down his weapon, the military can treat him like a threat.

Rhinos Without Borders has partnered with tourism venture andBeyond (pictured), who moved rhinos from one of their private reserves to Botswana in 2011. It costs roughly $45,000 to move a single rhino. Courtesy of AndBeyond
Rhino candidates are sedated and their blood samples studied to make sure they're strong enough to make the trip. The rhinos then recover during a six-week quarantine before they're moved by plane to a secret location in Botswana. Courtesy of AndBeyond
Because rhinos' first instinct is to seek out other herds, and Botswana has a low rhino density, synthesized rhino dung is used to help the relocated animals establish their territory. Beverly Joubert/Rhinos Without Borders
