South Africa is home to three of the world's 36 biodiversity hotspots. One is the Succulent Karoo, covering 116 000 km2 in Western and Northern Cape provinces and across the border into Namibia. The Succulent Karoo is the world's most biodiverse arid region, with many of its species occurring nowhere else on Earth. It houses the planet's largest concentration of succulents, all of which are uniquely adapted to thrive in aridity.
Endangered plants are protected by national and provincial legislation. In the Western Cape, it's illegal to harvest, be in possession of, or sell endangered plants without a permit -- even if you are the owner of the land where these plants grow.
