Populations are also found in montane and highland environments at higher elevations.

Range

Found in Kenya. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Colton's Milkvetch

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

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.
