In the arid far-western region of South Africa is a vast flatland covered with white quartzite gravel known as the Knersvlakte – Afrikaans for “Gnashing Plain” – because it sounds like grinding teeth when you walk across it. It’s a good place to watch unpeopled horizons vanish into ripples of heat haze, but to appreciate its real value you must get down on your knees. The Knersvlakte holds about 1,500 species of plants, including 190 species found nowhere else on earth and 155 that are Red-Listed by conservation biologists as threatened with extinction. To protect them, 211,000 acres have been set aside as the Knersvlakte Nature Reserve.
