The Cape Floral Region is a floristic region located near the southern tip of South Africa. It is the only floristic region of the Cape Floristic Kingdom, and includes only one floristic province, known as the Cape Floristic Province.
The Cape Floristic Region, the smallest of the six recognised floral kingdoms of the world, is an area of extraordinarily high diversity and endemism, and is home to over 9,000 vascular plant species, of which 69 percent are endemic. [1] Much of this diversity is associated with the fynbos biome, a Mediterranean-type, fire-prone shrubland. [1] The economical worth of fynbos biodiversity, based on harvests of fynbos products (e.g. wildflowers) and eco-tourism, is estimated to be in the region of R77 million (~US$5 million) a year. [1] Thus, it is clear that the Cape Floristic Region has both economic and intrinsic biological value as a biodiversity hotspot. [1]
Home to the greatest non-tropical concentration of higher plant species in the world, the region is the only hotspot that encompasses an entire floral kingdom, and holds five of South Africa's 12 endemic plant families and 160 endemic genera. Covering 78,555 km2, Cape Floristic Region hotspot is located entirely within the borders of South Africa.
It is one of the five temperate Mediterranean-type systems on the hotspots list, and is one of only two hotspots that encompass an entire floral kingdom (the other being New Caledonia)[ citation needed ].
The Region covers the Mediterranean climate region of South Africa in the Western Cape in the southwestern corner of the country, and extends eastward into the Eastern Cape, a transitional zone between the winter rainfall region to the west and the summer-rainfall region to the east in KwaZulu-Natal.
Most of the region is covered with fynbos, a sclerophyllous shrubland occurring on acid sands or nutrient-poor soils derived from Table Mountain sandstones (Cape Supergroup). Fynbos is home to a diverse plethora of plant species including many members of the protea family (Proteaceae), heath family (Ericaceae), and reed family of restios (Restionaceae). Other vegetation types are sandveld, a soft coastal scrubland found mostly on the west-facing coast of the Western Cape Province, on tertiary sands. Renosterveld is a grassy shrubland dominated by members of the daisy family (Asteraceae), particularly renosterbos (Elytropappus rhinocerotis), graminoids and geophytes, occurring on the base-rich shaley soils of the coastal forelands. Small pockets of Afromontane forest (Southern Afrotemperate Forest) can be found in humid and sheltered areas.
According to Takhtajan (1978), the following families are endemic or subendemic to the region: Grubbiaceae, Roridulaceae, Bruniaceae, Penaeaceae, Greyiaceae, Geissolomataceae, Retziaceae ( Retzia ) and Stilbaceae. [2] [3] Rooibos is produced out of this region.

The World Wide Fund for Nature divides the Cape floristic region into three ecoregions: the Lowland fynbos and renosterveld, Montane fynbos and renosterveld and the Albany thickets.
The fynbos ecoregions are designated one of the Global 200 priority ecoregions for conservation. Conservation International declared the Cape floristic region to be a biodiversity hotspot.
It is thought that the Cape Floristic Region is experiencing one of the most rapid rates of extinction in the world due to habitat loss, land degradation, and invasive alien plants. [6]
In 2004, the "Cape Floral Region Protected Areas" were inscribed as a World Heritage Site. The site includes eight representative protected areas:
Fynbos is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% species of the Cape floral kingdom, where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it.
The Kogelberg is a range of mountains along the False Bay coast in the Western Cape of South Africa. They form part of the Cape Fold Belt, starting south of the Elgin valley and forming a steep coastal range as far as Kleinmond.
The wildlife of South Africa consists of the flora and fauna of this country in southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 849 species of bird and over 20,000 species of vascular plants.
Renosterveld is a term used for one of the major plant communities and vegetation types of the Cape Floristic Region which is located in southwestern and southeastern South Africa, in southernmost Africa. It is an ecoregion of the Mediterranean forests, woodlands, and scrub biome.
The Biodiversity of Cape Town is the variety and variability of life within the geographical extent of the City of Cape Town metropolitan municipality, excluding the Prince Edward Islands. The terrestrial vegetation is particularly diverse and much of it is endemic to the city and its vicinity. Terrestrial and freshwater animal life is heavily impacted by urban development and habitat degradation. Marine life of the waters immediately adjacent to the city along the Cape Peninsula and in False Bay is also diverse, and while also impacted by human activity, the habitats are relatively intact.
Swartland Alluvium Fynbos is a critically endangered vegetation type that occurs on the high plains and mountains in the far south-west of the Western Cape, South Africa.
Lourensford Alluvium Fynbos is a critically endangered vegetation type that is endemic to Cape Town. Though closest to Fynbos, it has characteristics of both Fynbos and Renosterveld vegetation and is thus actually a unique hybrid vegetation type.
Kogelberg Sandstone Fynbos is a critically endangered vegetation type occurring in the far south of the Western Cape, South Africa.
Peninsula Shale Renosterveld (PSR) is a unique vegetation type that is found only on the slopes of Signal Hill and Devil's Peak in Cape Town, South Africa. It is critically endangered and exists nowhere else.
Swartland Shale Renosterveld is a critically endangered vegetation type of the Western Cape, South Africa.
Cape Winelands Shale Fynbos is a vegetation type that naturally occurs in the Cape Winelands of the Western Cape, South Africa.
Durbanville Nature Reserve is a 6-hectare (15-acre) piece of protected land, located next to the Hollywoodbets Durbanville Racecourse in the Western Cape, South Africa.
Helderberg Nature Reserve is a 398-hectare (980-acre) nature reserve in Somerset West, South Africa.
Blaauwberg Nature Reserve was proclaimed a local and provincial nature reserve in 2007. The reserve has views down fynbos slopes, across the city, to seven kilometres of rocky and sandy coastline and the ocean and beyond. The reserve presents itself as one of the few viewpoints in the world from where you can see two proclaimed world heritage sites, namely Table Mountain and Robben Island.
Silwerboomkloof Natural Heritage Site is a small, protected valley (“kloof”), near the Helderberg Nature Reserve, in Somerset West, South Africa.
Kogelberg Nature Reserve is a nature reserve of 3,000 ha comprising the Kogelberg Mountain Range, to the east of Cape Town, South Africa.
Mediterranean scrub is a biome defined by the World Wide Fund for Nature. The biome is generally characterized by dry summers and rainy winters, although in some areas rainfall may be uniform. Summers are typically hot in low-lying inland locations but can be cool near colder seas. Winters are typically mild to cool in low-lying locations but can be cold in inland and higher locations. All these ecoregions are highly distinctive, collectively harboring 10% of the Earth's plant species.
The Cape Winelands Biosphere Reserve is located in the Western Cape Province of South Africa approximately 40 km (25 mi) east of Cape Town. The Biosphere Reserve extends from the Kogelberg Biosphere Reserve in the south, northwards along the Cape Fold Belt Mountain Chain and the adjoining valleys constituting the Cape Winelands. The Biosphere Reserve incorporates key portions of the registered Cape Floral Region Protected Areas World Heritage Site. The Reserve was designated in 2007.
The Biodiversity of South Africa is the variety of living organisms within the boundaries of South Africa and its exclusive economic zone. South Africa is a region of high biodiversity in the terrestrial and marine realms. The country is ranked sixth out of the world's seventeen megadiverse countries, and is rated among the top 10 for plant species diversity and third for marine endemism.
