Assessment rationale/justification
Despite being restricted to the Hajar Mountains and Ru'us al-Jibal in the UAE, this species is known to occur within at least one protected area in its range. In addition, it has been suggested that its supposed rarity may instead be due to being overlooked rather than actually being scarce. It is therefore assessed as Least Concern.

Habitat details as listed in assessment
This annual species has similar ecology to Geranium mascatense: it has round, lobed leaves and dark pink flowers with a black centre, which can be seen between February and May (Jongbloed et al. 2003). However, Geranium trilophum is thought to have larger flowers (Jongbloed et al. 2003). Similarly to G. mascatense, it may well inhabit gravel substrate, in addition to shady places within both wadis and plantations (Jongbloed et al. 2003). Within the Wadi Wurayah National Park, this species is known to grow on north-facing rubble slopes which are shaded by a cliff (Feulner 2016).
