The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists are produced by countries and organizations, which assess the risk of extinction to species within a political management unit.
The Mohave ground squirrel is a species of ground squirrel found only in the Mojave Desert in California. The squirrel was first described in 1886 by Frank Stephens of San Diego. It is listed as a threatened species under the California Endangered Species Act, but not under the federal Endangered Species Act. The IUCN lists this species as near threatened.

Astragalus nitidiflorus is a species of legume in the family Fabaceae. It is endemic to Cartagena, southeast of Spain. It was refound after about 100 years of extinction and "the reappearance of this species has awakened the interest of environmental managers because the reasons for its critical situation are unknown". In 2004, a group of 46 specimens were discovered in a protected area between Cartagena and Mazarrón and plans for the conservation of this species have been implemented. ISSR markers helped to find that Astragalus nitidiflorus has a low genetic diversity. "This species grows in shallow soil from metamorphic and volcanic rocks in between mountain and cultivated areas".

Under the synonym Astragalus albanicus, the 2014 IUCN Red List assessed it as "endangered", stating that it was endemic to the Abşeron and Gobustan districts of Azerbaijan, where it can be found on dry clayey sites and shingle slopes up to the mid montane zone and is threatened by small-scale development.
Astragalus coarctatus is a species of milkvetch that is endemic to northeastern Turkey, and is only known from its type specimen, collected in 1871 in Kars Province.
