Threatened Species are any species which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment.
Dalbergia melanoxylon is a flowering plant in the family Fabaceae, native to seasonally dry regions of Africa from Senegal east to Eritrea and south to the north-eastern parts of South Africa. The tree is an important timber species in its native areas; it is used in the manufacture of musical instruments and fine furniture. Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by overharvesting due to poor or absent conservation planning and by the species' low germination rates.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
Leucadendron argenteum is an endangered plant species in the family Proteaceae, which is endemic to a small area of the Cape Peninsula, South Africa. Most grow in and around the city of Cape Town, but outlying populations exist near Somerset West (Silwerboomkloof), Paarl and Stellenbosch. It is a protected tree in South Africa.
Colubrina is a genus of about 30 species of flowering plants in the family Rhamnaceae, native to warm temperate to tropical regions of Africa, the Americas, southern Asia, northern Australia, and the Indian Ocean islands. Common names include nakedwood, snakewood, greenheart and hogplum. The generic name is derived from the Latin word coluber, meaning "snake", and refers to the snake-like stems or stamens.
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.
Erythrina schliebenii is a species of legume in the family Fabaceae. It is found only in Tanzania. The species is named for German collector and botanist Hans-Joachim Schlieben.
Tephrosia pondoensis is a species of legume in the family Fabaceae. It is found only in South Africa, where it is protected under the National Forest Act of 1998. The pondo poison pea is threatened by habitat loss.
Podocarpus elongatus, the Breede River yellowwood, is a species of conifer in the family Podocarpaceae. In contrast to other yellowwood species of southern Africa, Podocarpus elongatus often resembles an enormous, round, multi-stemmed bush in its habit. The Breede River yellowwood is a protected tree in South Africa.
Widdringtonia wallichii, Clanwilliam cedar or Clanwilliam cypress, previously Widdringtonia cedarbergensis is a species of Widdringtonia native to South Africa, where it is endemic to the Cederberg Mountains northeast of Cape Town in Western Cape Province. It is threatened by habitat loss and protected in South Africa under the National Forest Act of 1998.
Widdringtonia schwarzii is a species of Widdringtonia native to South Africa, where it is endemic to the Baviaanskloof and Kouga Mountains west of Port Elizabeth in Eastern Cape Province; it occurs on dry rocky slopes and crags at 600-1,200 m altitude. It is threatened by habitat loss, particularly by wildfire. The Willowmore cypress is a protected tree in South Africa.
Cassipourea swaziensis is a species of plant in the Rhizophoraceae family. It is found in South Africa and Swaziland. It is threatened by habitat loss, and a protected tree in South Africa.
Erythrophysa transvaalensis is a species of plant in the family family Sapindaceae. It is a protected tree in South Africa. It is found in Botswana, South Africa, and Zimbabwe. Its range is disjunct however, so that suggestions have been made that its seeds were formerly employed as beads, which assisted its dispersal along ancient trade routes.
Manilkara nicholsonii is a species of plant in the family Sapotaceae. It is endemic to South Africa (Natal), and is threatened by habitat loss.
Ozoroa namaquensis is a species of plant in the family Anacardiaceae. It is found in Namibia and South Africa. It is threatened by habitat loss, and a protected tree in South Africa.
Protea comptonii, also known as saddleback sugarbush, is a smallish tree of the genus Protea in the family Proteaceae. It is found in South Africa and Eswatini.
Protea curvata is a species of plant in the family Proteaceae. It is endemic to South Africa, and a protected tree there.
Colubrina oppositifolia, known as kauila in Hawaiian, is a species of flowering tree in the family Rhamnaceae, that is endemic to Hawaii. It can be found in dry, coastal mesic, and mixed mesic forests at elevations of 240–920 m (790–3,020 ft) on the islands of Oʻahu and Hawaiʻi. There is also one individual remaining on Maui. Associated plants include alaheʻe and ʻohe kukuluāeʻo.
Ceriops tagal, commonly known as spurred mangrove or Indian mangrove, is a mangrove tree species in the family Rhizophoraceae. It is a protected tree in South Africa. The specific epithet tagal is a plant name from the Tagalog language.
