Habitat: Evergreen forests, maquis shrubland and spiny scrublands up to 1500-1800 m, on any kind of soils. It can appear as a dominant species.
Variability: Very variable in size and aspect of the whole plant, leaves and acorns. Western Mediterranean forms use to be shrubby (multi-trunk plants, up to 4-5 m tall), and most Eastern ones are trees with one or few well-defined tall trunks. Populations by the Eastern edge has been described as subsp. calliprinos (Webb) Holmboe (=Q. calliprinos Webb). In addition several subespecies often not accepted by most taxonomists have been proposed around the Mediterranean.

FILMED's selected populations: Q. coccifera s.s.: Argelia (4), France (4), Greece (5), Italy (2), Marocco (5), Portugal (2), Spain (32), Tunisia (1) and Turkey (5).
In addition the following populations apparently belonging to Q. coocifera subsp. calliprinos have been sampled: Cyprus (2), Israel (2), Italy (1) and Lybia (3)
Note: Western populations (Greece, Turkey) can include transitions between the two subespecies.
