Iberolacerta bonnali has not the easiest life: As a high altitude mountain lizard it inhabits areas up to 3000 meters which only allow a short activity phase in summer. However, it has to compete against Podarcis muralis, which seems to occupy the habitats with more favorable microclimate. Moreover, it faces potential predation pressure by Vipera aspis which also occurs in its biotopes.
The distribution area of the Pyrenean Rock Lizard is restricted to the central Pyrenees of Spain and France where it occurs locally, often in rather low population densities.
It co-occurs with the following species:
Iberolacerta bonnali differs from other Pyrenean Rock Lizard species by the following characters: Iberolacerta aranica has three characteristic big masseteric scales. Iberolacerta aurelioi frequently has a yellow underside.
