Cape Lowland Freshwater Wetland is a critically endangered vegetation type of the Western Cape, South Africa.
Cape Lowland Freshwater Wetland is a critically endangered vegetation type of the Western Cape, South Africa.
This type of riparian vegetation and its accompanying ecosystem is found in the Western Cape, South Africa, on freshwater floodplains, along the lower stretches of rivers and around seasonal vleis and estuaries. The terrain is typically flat and the soil is rich and silty. It is restricted to a winter rainfall area.
This used to be one of the major ecosystems on the Cape Flats of Cape Town. The Cape Flats used to have a great many wetlands, rivers and seasonal vleis, but these have largely been drained and built over for housing. A few remain at places such as Rondevlei.
The flora consists of a range of species of tall reed (e.g. Phragmites australis , Typha capensis ), Restios, sedges, grasses, floating aquatics and a great many species of shrub. Plant cover is very high. Sedgelands predominate on the floodplains, floating aquatics grow in the open pools, taller shrubs and small trees grow in drier soils (e.g. Erica and Restio sp.) and the taller, bigger reed-beds dominate on the fringes of permanent water. Some of the most noticeable and dominant species are Senecio halimnifolius , Paspalum vaginatum , Pennisetum macrourum , Triglochin bulbosa , Bolboschoenus maritimus and Juncus krausii .
Plant species which are endemic to this vegetation type include: Passerina paludosa , Aponogeton angustifolius , Aponogeton distachyos , and Cotula myriophylloides . This ecosystem is not particularly rich in endemics (by Cape Floristic Region standards) but is an exceptionally rich and important habitat for the Waterbirds and Frogs of the Cape. It is also the breeding ground of the endangered Western Leopard Toad. [1] [2]
These ecosystems are threatened by invasive alien plants such as Kikuyu grass, Water Hyacinth ( Eichornia crassipes ), Red River Gum ( Eucalyptus cladocalyx ) and Port Jackson ( Acacia saligna ), as well as the draining and diversion of water for agricultural reasons and development. A significant proportion of these wetlands have now been transformed and lost and the ecosystem as a whole is now classed as endangered. All remaining wetlands are protected by national legislation.

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 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.
Aponogeton distachyos or Aponogeton distachyum, also known as waterblommetjie, Cape-pondweed, water hawthorn, vleikos and Cape pond weed is an aquatic flowering plant.
The Rondevlei Nature Reserve is located in Grassy Park, Zeekoevlei and Lavenderhill, suburbs of Cape Town, South Africa. The bird sanctuary covers approximately 290 hectares of mostly permanent wetland and consists of a single large brackish lagoon. The nature reserve is among the most important wetlands for birds in South Africa despite being situated directly alongside the Zeekoevlei. A number of islands on the vlei act as vital breeding sites. Rondevlei is home to about 230 bird species, a variety of small mammals and reptiles like caracal, porcupine, Cape fox, grysbuck, steenbuck and mongoose, as well as a hippopotamus population which was re-introduced in 1981 as a means to control an alien grass species from South America, which had covered the shoreline and was threatening to engulf the vlei itself. It boasts unusual and threatened ecosystems like strandveld, sand plains fynbos, Cape lowland wetland vegetation and indigenous coastal fynbos vegetation with unique plants found nowhere else in the world.
The Cape Floristic 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 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 858 species of bird and over 20,000 species of vascular plants.
The western leopard toad is a species of toad in the family Bufonidae. The species is endemic to the low-lying areas of the Cape Peninsula, the Cape Flats and the Agulhas flats of the Western Cape, South Africa.
The micro frog, or Cape Flats frog, is a species of frog less than 2 cm (0.8 in) long in the family Pyxicephalidae, in the monotypic genus Microbatrachella. Its colour varies from rufous brown with dark mottling, to tan or green, depending on the population. It is endemic to south-western Cape area of South Africa, with a single population found on the Cape Flats of Cape Town and several populations on the eastern side of False Bay. It typically lives in wetlands in coastal fynbos habitats, but its total area of occupancy is very small, and the International Union for Conservation of Nature has rated it as being "critically endangered"
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.
Cape Flats Dune Strandveld is an endangered vegetation type. This is a unique type of Cape Strandveld that is endemic to the coastal areas around Cape Town, including the Cape Flats.
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.
Hangklip Sand Fynbos is an endangered vegetation type that occurs in the southern coastal portion 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.
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.
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.
