The plant grows in undisturbed areas of the crust. It can be found at about 13 sites in a seven-by-three-mile range.
It is one of several rare plants and animals endemic to the Ash Meadows—Amargosa Valley area. Other plants occurring in the area include saltgrass (Distichlis spicata), shadscale (Atriplex confertifolia), and alkali goldenbush (Isocoma acradenia).
Astragalus phoenix is a federally listed threatened species.
Threats to this species include the destruction of or damage to its unique habitat. Alterations in the hydrology of the region occur when pumping or other processes affects the flow of the springs and seeps. Road construction, mining operations, and agriculture reduced the plant's numbers.
