The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Impatiens is a genus of more than 1,000 species of flowering plants, widely distributed throughout the Northern Hemisphere and the tropics. Together with the genus Hydrocera, Impatiens make up the family Balsaminaceae.
Mount Cameroon is an active volcano in the South West region of Cameroon next to the city of Buea near the Gulf of Guinea. Mount Cameroon is also known as Cameroon Mountain or Fako or by its indigenous name Mongo ma Ndemi. It is the highest point in sub-Saharan western and central Africa, the fourth-most prominent peak in Africa, and the 31st-most prominent in the world.
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.
Campylospermum oliveri is a species of plant in the Ochnaceae family. It is endemic to Cameroon. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Impatiens etindensis is a species of flowering plant in the family Balsaminaceae. It is endemic to Cameroon, where it is known only from Mount Cameroon. It grows as an epiphyte on trees in mountain forest habitat.
Impatiens frithii is a species of flowering plant in the family Balsaminaceae. It is endemic to Cameroon, where it has been found in the Bakossi Mountains and on Etinde, part of Mount Cameroon. It is an epiphyte growing on small trees and shrubs in elfin forest habitat. It is small and inconspicuous when not bearing its bright red flowers.
Impatiens grandisepala is a species of flowering plant in the family Balsaminaceae. It is endemic to Cameroon, where it is known only from Mount Cameroon. It has been collected only once, in 1979. It is an epiphyte that grows in shady mountain forest habitat.
Impatiens meruensis is a species of flowering plant in the family Balsaminaceae. It is found in Kenya, Sudan, Tanzania, and Uganda. Its natural habitats include mountain forests, streambanks, and swamps. It may grow in the spray zones of waterfalls. It is generally a widespread species in its range, at least in the uplands of Kenya.
Impatiens morsei is a species of flowering plant in the family Balsaminaceae. It is endemic to China, where it only occurs in Guangxi.
Impatiens obesa is a species of plant in the family Balsaminaceae. It is endemic to China.
Impatiens omeiana is a species of flowering plant in the family Balsaminaceae. It is endemic to China, where it occurs in Sichuan.
Impatiens pritzelii is a species of plant in the family Balsaminaceae. It is endemic to China.
Impatiens sakeriana is a species of flowering plant in the family Balsaminaceae. It is native to Cameroon and Equatorial Guinea. It grows in mountain forest understory habitat at altitudes up to 2000 meters. It occurs on Mount Cameroon. It can be locally common in parts of its range, but its habitat is threatened by agriculture.
Impatiens wilsoni is a species of flowering plant in the family Balsaminaceae. It is endemic to China, where it is known only from Sichuan.
Ledermanniella letouzeyi is a species of plant in the family Podostemaceae. It is endemic to Cameroon. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
Tapinanthus letouzeyi is a species of plant in the family Loranthaceae. It is endemic to Cameroon. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
Bombus impatiens, the common eastern bumble bee, is the most commonly encountered bumblebee across much of eastern North America. They can be found in the Eastern temperate forest region of the eastern United States, southern Canada, and the eastern Great Plains. Because of their great adaptability, they can live in country, suburbs, and even urban cities. This adaptability makes them a great pollinator species, leading to an increase in their commercial use by greenhouse industry. This increase consequently led to their farther spread outside their previous distribution range. They are considered one of the most important species of pollinator bees in North America.
Hydrocera is a genus of flowering plants in the family Balsaminaceae (balsams). It contains a single species, Hydrocera triflora, from Southeast Asia. It is the only other genus in the family Balsaminaceae besides Impatiens.
Bombus brachycephalus is a species of bumblebee native to Mexico and Central America. This bee occurs in mountain and highland regions, where it lives in various types of forests. It is active year-round in many areas.
