For example, a medieval Slavic settlement of Dubrava later formed the city of Dubrovnik; the species of oak that grows in that area is Quercus ilex L.
Both Sessile Oak Quercus petraea and Pendunculate Oak Quercus robur, Britain's two native oaks are used and also some introduced species such as Turkey Oak Quercus cerris and Evergreen oak Quercus ilex.
On northern slopes, drier areas, and higher elevations, Quercus ilex is found, along with conifers representing Abies, Picea, Cedrus, and Pinus.

The bulk of the acorn harvest comes from the holm oak (from November to February), but the season would be too short without the earlier harvests of Spanish oak and gall oak and the late cork oak season, which, between them, stretch the acorn-production period from September almost to April.
Large part of the mountain area, including the Selakano valley, are forested with pines (Pinus brutia), Kermes oaks (Quercus coccifera), cypresses (Cupressus sempervirens), Holm Oaks (Quercus ilex) and Cretan Maples (Acer sempervirens).
The original paper describing the species, stated it can infect Magnolia and Camellia species, Pieris formosa, Gevuina avellana, Michelia doltsopa and Quercus ilex.
The highest population densities are in open grazed Holm Oak woods, and in urban habitats such as Gibraltar, where it is common.
