Hill country in the Jerash-Ajlun mountains between 500 and 900 m with some steep slopes, dominated by a dense Mediterranean woodland of evergreen Quercus and Pistacia, with an understorey of Arbutus, Juniperus, Crataegus, Prunus, Rhamnus and Ceratonia. The reserve is part of the largest remaining tract of undisturbed oak woodland in the country, and is closely surrounded by villages and farmland; there are scattered patches of cultivation in the area (grapes, olives, wheat, barley).
