A. wheeleri grows in wet riparian areas, or seeps and springs.

Angelica wheeleri is rare, and has only be found in as few as 11 locations across 6 counties in Utah (Cache, Salt Lake, Utah, Juab, Sevier, and Piute). It is found in elevations between 1524 and 3050 meters. As a wetland plant native to a desert climate, A. wheeleri is at risk from rising temperatures and longer summers, urban development, stream channelization, water diversions, and other watershed and stream alterations, recreation, and invasive exotic plants. A. wheeleri was also found in the scat of black bears in the Hobble Creek area, a sign on natural herbivory that may also present risk to this plant.
