  South Africa signed the Rio Convention on Biological Diversity on 4 June 1994 and became a party to the convention on 2 November 1995. It has subsequently produced a National Biodiversity Strategy and Action Plan, which was received by the convention on 7 June 2006. The country is ranked sixth out of the world's seventeen megadiverse countries. Ecotourism in South Africa has become more prevalent in recent years, as a possible method of maintaining and improving biodiversity.
  
  Numerous mammals are found in the Bushveld including lions, African leopards, South African cheetahs, southern white rhinos, blue wildebeest, kudus, impalas, hyenas, hippopotamuses and South African giraffes. A significant extent of the Bushveld exists in the north-east including Kruger National Park and the Sabi Sand Game Reserve, as well as in the far north in the Waterberg Biosphere. South Africa houses many endemic species, among them the critically endangered riverine rabbit (Bunolagus monticullaris) in the Karoo.
  
  Up to 1945, more than 4,900 species of fungi (including lichen-forming species) had been recorded. In 2006, the number of fungi in South Africa was estimated at 200,000 species but did not take into account fungi associated with insects. If correct, then the number of South African fungi dwarfs that of its plants. In at least some major South African ecosystems, an exceptionally high percentage of fungi are highly specific in terms of the plants with which they occur. The country's Biodiversity Strategy and Action Plan does not mention fungi (including lichen-forming fungi).
  
  With more than 22,000 different vascular plants, or about 9% of all the known species of plants on Earth, South Africa is particularly rich in plant diversity. The most prevalent biome is the grassland, particularly on the Highveld, where the plant cover is dominated by different grasses, low shrubs, and acacia, mainly camel-thorn (Vachellia erioloba). Vegetation is sparse towards the north-west because of low rainfall. There are numerous species of water-storing succulents, like aloes and euphorbias, in the very hot and dry Namaqualand area. And according to the World Wildlife Fund, South Africa is home to around a third of all succulent species. The grass and thorn savanna turns slowly into a bush savanna towards the north-east of the country, with denser growth. There are significant numbers of baobab trees in this area, near the northern end of Kruger National Park.
  
  The fynbos biome, which makes up the majority of the area and plant life in the Cape Floristic Region, is located in a small region of the Western Cape and contains more than 9,000 of those species, or three times more plant species than found in the Amazon rainforest, making it among the richest regions on earth in terms of plant diversity. Most of the plants are evergreen hard-leaf plants with fine, needle-like leaves, such as the sclerophyllous plants. Another uniquely South African flowering plant group is the genus Protea, with around 130 different species. While South Africa has a great wealth of flowering plants, only 1% of the land is forest, almost exclusively in the humid coastal plain of KwaZulu-Natal, where there are also areas of Southern Africa mangroves in river mouths. Even smaller reserves of forests are out of the reach of fire, known as montane forests. Plantations of imported tree species are predominant, particularly the non-native eucalyptus and pine.
  
  South Africa has lost a large area of natural habitat in the last four decades, primarily because of overpopulation, sprawling development patterns, and deforestation during the 19th century. The country had a 2019 Forest Landscape Integrity Index mean score of 4.94/10, ranking it 112th globally out of 172 countries. South Africa is one of the worst affected countries in the world when it comes to invasion by alien species with many (e.g., black wattle, Port Jackson willow, Hakea, Lantana and Jacaranda) posing a significant threat to the native biodiversity and the already scarce water resources. Also woody plant encroachment of native plants in grasslands poses a threat to biodiversity and related ecosystem services, affecting over 7 million hectares. The original temperate forest found by the first European settlers was exploited until only small patches remained. Currently, South African hardwood trees like real yellowwood (Podocarpus latifolius), stinkwood (Ocotea bullata), and South African black ironwood (Olea capensis) are under strict government protection. Statistics from the Department of Environmental Affairs show a record 1,215 rhinos were killed in 2014. Since South Africa is home to a third of all succulent species (many endemic to the Karoo), it makes it a hotspot for plant poaching, leading to many species to be threatened with extinction.
