Erica margaritacea | |
Erica margaritacea, the pearl heath, is a species of Erica naturally restricted to the city of Cape Town. It is critically endangered. [1]
Historically, the plant grew naturally in the Cape Flats Sand Fynbos of the Southern Suburbs, Cape Town. However, urban development caused it to go extinct in the wild. Specimens that were preserved by botanists were used to reintroduce this species to the last remaining patch of its habitat, the Kenilworth Racecourse Conservation Area.
It produces enormous amounts of white, pearl-shaped flowers and can readily be cultivated in urban gardens. [2]
Erica is a genus of roughly 857 species of flowering plants in the family Ericaceae. The English common names heath and heather are shared by some closely related genera of similar appearance. The genus Calluna was formerly included in Erica – it differs in having even smaller scale-leaves, and the flower corolla consisting of separate petals. Erica is sometimes referred to as "winter heather" to distinguish it from Calluna "summer heather".
Newlands Forest is a conservancy area on the eastern slopes of Table Mountain, beside the suburb of Newlands, Cape Town, South Africa. It is owned and maintained by the Table Mountain National Parks Board, along with the City Parks Department of Cape Town, and includes a Fire Station, Nursery and Reservoir.
A prostrate shrub is a woody plant, most of the branches of which lie upon or just above the ground, rather than being held erect as are the branches of most trees and shrubs.
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.
Cape Flats Sand Fynbos (CFSF), previously known as Sand Plain Fynbos, is a critically endangered vegetation type that occurs only within the city of Cape Town. Less than 1% of this unique lowland fynbos vegetation is conserved.
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.
Peninsula Granite Fynbos is an endangered Fynbos vegetation type which is endemic to the city of Cape Town and occurs nowhere else. It is a unique type of tall, dense and diverse scrubland, scattered with trees. It can be found all along the belt of granite that encircles Table Mountain.
Peninsula Sandstone Fynbos is a unique and endangered vegetation type that is endemic to the Cape Peninsula in Cape Town. This type of Mountain Fynbos occurs on very poor, acidic soils but is incredibly rich in biodiversity with an enormous number of plant species – many of which occur nowhere else. Due to its poor soils and steep, inaccessible location, it has not been developed for farming or houses, and consequently it is relatively well conserved.
Cape Winelands Shale Fynbos is a vegetation type that naturally occurs in the Cape Winelands of the Western Cape, South Africa.
Kenilworth Racecourse Conservation Area is a 52-hectare (130-acre) nature reserve, situated in the centre of Kenilworth Racecourse, in Cape Town, South Africa. Due to its location, it has been left undisturbed for more than 100 years, making it now the best preserved patch of “Cape Flats Sand Fynbos” in the world.
Witzands Aquifer Nature Reserve is a 3,000-hectare (7,400-acre) protected natural area in Cape Town, South Africa, located on the city's northern outskirts. This reserve protects an important part of Cape Town's natural and cultural heritage, including the Atlantis Aquifer. It is adjacent to the Koeberg Nature Reserve.
Erica verticillata is a species of Erica that was naturally restricted to the city of Cape Town but is now classified as extinct in the wild.
Erica turgida, the showy heath or Kenilworth heath, is a species of Erica that was naturally restricted to the city of Cape Town, South Africa, but is now classified as Extinct in the Wild.
Erica abietina is a species of erica that is endemic to the Cape Peninsula of the Western Cape, South Africa. E. abietina includes four subspecies with often highly restricted distributions and distinctive flower colours. Previous delimitation of the species has included a further three subspecies which proved to be more distantly related to Cape Peninsula endemic E. abietina subspecies and are now classified under Erica grandiflora L.f. and Erica situshiemalis E.G.H.Oliv. & Pirie.
Erica baccans, the berry heath, is a species of Erica that was naturally restricted to the city of Cape Town, South Africa.
Erica hirtiflora, the hairy-flower heath, is a species of Erica that was naturally restricted to the south-western corner of the Western Cape, South Africa around the city of Cape Town.
Erica mollis, the soft heath, is a species of Erica that was naturally restricted to the city of Cape Town, occurring nowhere else in the world.
Erica urna-viridis, the sticky heath or bottle-green heath, is a species of Erica that was naturally restricted to the city of Cape Town, South Africa, in particular the Peninsula Sandstone Fynbos of Table Mountain.
Erica ventricosa is a species of plant in the family Ericaceae native to the Cape Floristic Region.
Tokai Park, previously known as "Tokai Forest", is a small wing, about 600 ha, of the greater Table Mountain National Park in Cape Town, South Africa. Tokai Park is made up of two sections: upper and lower Tokai Park. Lower Tokai Park is flat, and characterized by the threatened Cape Flats Sand Fynbos. Upper Tokai Park is on the slopes of Constantiaberg Mountain, and consists of conservation area as well as the Tokai Arboretum. Upper Tokai Park is characterized by Peninsula Granite Fynbos, Peninsula Sandstone Fynbos and Afromontane Forest and noted for its diversity.
