Cape Floristic Region

Lore & Background

The Cape Floristic Region covers the Mediterranean climate region of South Africa in the Western Cape and extends eastward into the Eastern Cape. Much of its diversity is associated with the fynbos biome, a Mediterranean-type, fire-prone shrubland. Other vegetation types include sandveld, renosterveld, and small pockets of Afromontane forest. The region is the only hotspot that encompasses an entire floral kingdom, and holds five of South Africa's 12 endemic plant families and approximately 180–200 endemic genera.

Reader's Guide

The Cape Floristic Region is one of only two hotspots that encompass an entire floral kingdom (the other being New Caledonia). It is one of the five temperate Mediterranean-type systems on the hotspots list. The World Wide Fund for Nature divides the region into three ecoregions: Lowland fynbos and renosterveld, Montane fynbos and renosterveld, and Albany thickets. Conservation International declared it a biodiversity hotspot. The region is thought to be experiencing one of the most rapid rates of extinction in the world due to habitat loss, land degradation, and invasive alien plants. In 2004, the 'Cape Floral Region Protected Areas' were inscribed as a World Heritage Site, including eight representative protected areas such as Table Mountain National Park and the Cederberg Wilderness Area. The economical worth of fynbos biodiversity, based on harvests of fynbos products and eco-tourism, is estimated at R77 million (~US$5 million) a year.

Did You Know?

• The Cape Floristic Region is the only floristic region of the Cape Floristic Kingdom.
• It is home to over 9,000 vascular plant species, 69% of which are endemic.
• The region is one of the most economically valuable biodiversity hotspots, with fynbos contributing hundreds of millions to billions of rand annually through wildflower harvests and eco-tourism.

A Pocket of Extraordinary Life

The Cape Floristic Region holds a distinction that few places on Earth can claim: it is the smallest of the six recognized floral kingdoms yet packs an extraordinary concentration of plant life. With more than 9,000 vascular plant species, it supports the greatest non-tropical concentration of higher plant species anywhere in the world. What makes this even more remarkable is that 69 percent of those species are found nowhere else on the planet. The region shelters five of South Africa's twelve endemic plant families and 160 endemic genera, and according to the botanist Takhtajan, families such as Grubbiaceae, Roridulaceae, Bruniaceae, Penaeaceae, Greyiaceae, Geissolomataceae, Retziaceae, and Stilbaceae are either endemic or subendemic to this single area. It is the only hotspot that encompasses an entire floral kingdom, a distinction it shares solely with New Caledonia. All of this botanical richness is contained within a single floristic province, the Cape Floristic Province, making the region a singular, self-contained plant world.

The Fynbos Mosaic

The dominant vegetation of the region is fynbos, a sclerophyllous shrubland that thrives on acid sands and nutrient-poor soils derived from Table Mountain sandstones of the Cape Supergroup. This Mediterranean-type, fire-prone ecosystem harbors an astonishing array of plant families, including Proteaceae, Ericaceae, and Restionaceae. Beyond fynbos, the region hosts sandveld, a soft coastal scrubland on tertiary sands along the west-facing coast of the Western Cape, and renosterveld, a grassy shrubland dominated by Asteraceae members, particularly renosterbos (Elytropappus rhinocerotis), along with graminoids and geophytes on base-rich shaley soils. Small pockets of Southern Afrotemperate Forest cling to humid, sheltered areas. The vegetation types are remarkably specific: from Peninsula Granite Fynbos and Cape Flats Sand Fynbos around Cape Town, to Kogelberg Sandstone Fynbos in the far south, to the various Swartland Renosterveld variants. Rooibos, the well-known herbal tea, is also produced from this region.

A Mediterranean Corner of Africa

The Cape Floristic Region is situated entirely within South Africa's borders, covering 78,555 square kilometers in the southwestern corner of the country. It occupies the Mediterranean climate zone of the Western Cape and stretches eastward into the Eastern Cape, forming a transitional belt between the winter-rainfall region to the west and the summer-rainfall region of KwaZulu-Natal to the east. This positioning makes it one of only five temperate Mediterranean-type systems on the global biodiversity hotspots list. The region's climate and geography create conditions that have driven the extraordinary speciation and endemism found here. Its location near the southern tip of the continent, combined with nutrient-poor soils and fire-prone Mediterranean weather patterns, has shaped a flora unlike any other. The fact that it is the sole floristic region of the Cape Floristic Kingdom and contains only one floristic province underscores how geographically and botanically self-contained this slice of the African landscape truly is.

Under Threat, Under Protection

Despite its irreplaceable botanical wealth, the Cape Floristic Region faces one of the most rapid rates of extinction in the world, driven by habitat loss, land degradation, and invasive alien plants. Conservation International has designated it a biodiversity hotspot, and the WWF splits it into three ecoregions: Lowland fynbos and renosterveld, Montane fynbos and renosterveld, and the Albany thickets, with the fynbos ecoregions named among the Global 200 priority areas. In 2004, the Cape Floral Region Protected Areas earned World Heritage status, encompassing eight representative sites including Table Mountain National Park, the Cederberg Wilderness Area, the Boland Mountain Complex, De Hoop Nature Reserve, Boosmansbos Wilderness Area, the Swartberg Complex, and the Baviaanskloof Mega Reserve. The region also carries real economic weight: harvests of fynbos products such as wildflowers, combined with eco-tourism, generate roughly R77 million (about US$5 million) annually. Conservation South Africa, successor to Conservation International's South Africa programme, has worked with local partners on preservation efforts since the early 2000s.
