Succulent Karoo, South Africa.

In this desert region, overgrazing by livestock has degraded vast areas.

Reversing this trend, private landowners and government agencies are restoring large areas of this unique region.

The photo shows a small sample of the exceptional plant diversity of the Succulent Karoo; its 5,000 plant species include the highest diversity of succulent plants in the world, such as the rare Aloe pillansii.
