What are the 3 main biomes in Africa?
Three biomes were identified based on their major growth forms: savannas, 'thickets' and forest. Different species assemblages occurred in each biome. Functional traits of trees were filtered differently across biomes. Biomes in Hluhluwe-iMfolozi seem to be alternative stable states.

Why is the forest biome in South Africa so fragmented?
South African forests are naturally highly fragmented, but without a doubt human impacts in the form of fires, clearing, and agricultural land use change have exacerbated this fragmentation.
What is a fynbos shrub?
Fynbos (/ˈfeɪnbɒs/; Afrikaans pronunciation: [ˈfɛinbos] meaning fine-leaved plants) 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.
Why is fynbos so special?
It's valuable because it is under threat – due in no small part to agriculture, invading plant species, and human development. Fynbos is a totally unique kind of vegetation that makes up 80 per cent of the Cape Floral Kingdom, two-thirds of which are found only in the Cape (nowhere else on earth).
How many types of fynbos are there?
The fynbos constitutes about 80% of the Cape floral kingdom; of the more than 8,500 fynbos species, nearly 6,000 of them are endemic. 1,700 fynbos plant species are threatened with extinction.
What does fynbos look like?
Fynbos appears unimpressive from a distance. It is treeless, scrubby and brown – 'fine bush' in the sense of thin, straggly and not very productive. It is a heathland – resembling similar environments in Europe, Australia and South America growing in nutrient-deficient soil under tough climatic conditions.
Where is fynbos found?
What animals live in the fynbos?
There are very few trees or grasses in Fynbos. Animals include small buck like Grysbok and Steenbok, the Bontebok, Leopard, Chacma Baboon, Porcupine, tortoises and nectar- and seed-eating birds. Many people in this biome are employed to harvest Fynbos plants.
Why is fire important for the fynbos vegetation?
Fire acts as mineralizing agent in fynbos in that the ash left after the fire returns mineral elements that were held above ground by the plants back to the soil. The disturbance that fire causes also makes water, nutrients and light more available for a certain period after the fire.
How are fynbos adapted to survive?
Fynbos is a fire-adapted vegetation that requires regular burning for its persistence. In the absence of fire, fynbos is gradually replaced by thicket species. ... They complete their short life cycles, returning to the soil as the larger shrubs overwhelm them, and remain dormant until the next fire.
How often is it necessary to burn veld in the fynbos regions?
Research suggests that, under natural conditions the minimum fire return interval for moist mountain and lowland fynbos should be between 12 and 20 years and arid moun- tain fynbos 25 years, whilst that of moist renosterveld (e.g. in coastal plain areas) should be around 10 years and arid renosterveld (e.g. the inland ...
Which plants need fire to germinate?
These plants rely on an environmental cue—in this case, fire—to know when to drop their seeds. They include species of hakea, banksia and eucalypts. Banksias, for example, can keep their seed for years in a woody fruit called a follicle. During a fire, the parent plant may be killed but the fruit will open up.
Which South African biomes is the richest in terms of endemic plant species diversity?
The Succulent Karoo biome is home to the world's richest succulent flora. It has approximately 1954 endemic plant species, and is the only semi-arid region to qualify as a hotspot of global significance. Despite its importance, only 2% of the biome is currently protected.
In which biome will you find yellowwood Stinkwood?
Forest Biome The most famous, largest forests in South Africa are the Knysna and Tsitskamma Forests in the Southern Cape. Forests plants contain yellowwood, stinkwood and ironwood trees, climbers, epiphytes, mosses and ferns.
What restricts the International Trade in Endangered Species?
The Convention on International Trade in Endangered Species (CITES), which was introduced in 1973 and entered into force in 1975, prohibits international trade in endangered species by assigning each protected species to one of three lists. ... Only export permits are required for Appendix II and III species.
