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.
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of 2021, of the 120,372 species currently tracked by the IUCN, there are 8,404 species that are considered to be Critically Endangered.
Notiosorex cockrumi, also called Cockrum's gray shrew or Cockrum's desert shrew, is a tiny species of shrews named in 2003. This red-toothed shrew, which is as light as a penny, is the first new mammal species from Arizona since 1977. Its range extends from Arizona to central Sonora, Mexico.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.

Lomanthus fosbergii, synonym Talamancalia fosbergii, is a species of flowering plant in the family Asteraceae endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. It was first described by José Cuatrecasas in 1953 as Senecio fosbergii. The genus Lomanthus is placed in the tribe Senecioneae.
Talamancalia is a genus of flowering plant in the family Asteraceae. It contains the following species:
Crocidura grandiceps is a species of mammal in the family Soricidae. It is found in Benin, Ivory Coast, Ghana, Guinea, Liberia, Nigeria, and Togo. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss due to agriculture and aquaculture as well as logging and wood harvesting. To increase habitat protection for the C. grandiceps, in-place land/water protection conservation actions are in place. The vernacular name large-headed shrew is sometimes applied to C. grandiceps but has also been used for the entire related genus Paracrocidura. The IUCN List categorizes the C. grandiceps as Near Threatened as of 2008.
