The Hottentots Holland Reserve iis important for the conservation of mountain fynbos with approximately 1300 species occurring here, including several rare and endemic plants.
The Houwhoek Pass is in close proximity to the Kogelberg Biosphere near Kleinmond. This is covered under Clarence Drive and is repeated here.
A trip to experience Houwhoek Pass should involve a return route around the back of the mountain over Clarence Drive, a truly breathtaking experience.
Presenting perhaps the finest collection of mountain fynbos in the Western Cape, the Kogelberg Biosphere, adjacent to Clarence Drive, has been protected by the isolation of the area.It has largely been kept clear of alien vegetation.
Boasting a species list of 1654 plant species (150 endemic), many spectacular members of the Protea family, including the endangered Marsh Rose, occur here. At one time close to extinction it is now known to occur in a few mostly inaccessible peaks.
The Biosphere has three patches of relic indigenous forest, Louwsbos, Platbos and Oudebos. Similar to the Knysna forests, they include yellowwood, stinkwood and boekenhout trees.
The Palmiet River and its associated riparian vegetation is of the most pristine in the south-western Cape.
Wild almond, rooi-els, yellowwood and Cape beech are among the trees occurring in the riverine scrub.
