Colton's Milkvetch

Astragalus coltonii, Colton's milkvetch, is a perennial legume in the family Fabaceae assessed as Least Concern by the IUCN. The genus Astragalus is the largest genus of flowering plants globally, with over 3,000 species distributed primarily in temperate and arid regions of the Northern Hemisphere. Astragalus coltonii inhabits diverse terrestrial environments, typically including semi-arid shrublands, rocky soils, and open desert margins where competition from taller vegetation is limited. Like other milkvetches, this species likely forms root associations with nitrogen-fixing bacteria, enabling it to colonise nutrient-poor substrates and contribute to soil fertility improvement in its habitat. The pinnately compound leaves, pea-type flowers, and inflated seed pods characteristic of the genus are typical features of this species. Milkvetches provide forage for native pollinators and serve as larval host plants for several butterfly and moth species. Some Astragalus species accumulate selenium or alkaloids from the soil, making them toxic to livestock, though the toxicological properties of A. coltonii specifically have not been well characterised. Biological traits of this species remain poorly documented in the scientific literature.

호주 동부와 동남부의 상징적인 유대류로, 체중이 최대 15kg이며 저칼로리인 유칼립투스 잎 식단에서 에너지를 절약하기 위해 하루 최대 22시간을 잠으로 보낸다. 대부분의 다른 포유류를 죽일 수 있는 유독한 유칼립투스 성분을 처리하도록 고도로 특화되어, 해독에 특별히 적응된 장내 미생물총을 지닌다. 2022년 기후 변화, 서식지 개발, 클라미디아 감염으로 인한 개체수 감소로 위기종으로 지정되었다.
