Kogelberg Sandstone Fynbos is a critically endangered vegetation type occurring in the far south of the Western Cape, South Africa. This type of mountain fynbos contains an extremely high number of threatened species and a great number of the plants that occur here can be found nowhere else on earth. It naturally occurs from the eastern outskirts of Cape Town, eastwards through the Kogelberg and Hottentots-Holland mountains, as far as Kleinmond, and it is conserved within the Kogelberg Biosphere Reserve.
