Justification
Astragalus abnormalis is currently only known from two specimens (Koelz #15768, Rioux and Golvan #001901) collected respectively in 1940 and 1960. There is no data about its ecological preference, population size, trends and possible threats. Further research and field work is required to better understand the distribution range and health of this species and to make sure that it is still extant.

Threats

Major Threats
Agricultural cultivation, overgrazing and over-harvesting of woody vegetation for fuel have contributed greatly to the reduction in areas of natural vegetation in the ecoregion where the species is believed to occur and continue to pose significant threats to the natural vegetation.
