The forests of Greece cover approximately 30% of the country and are an important part of its natural heritage. Depending on elevation, distinct vegetation zones can be discerned; from Mediterranean forests in lowland areas, to oak and chestnut forests in semi-mountainous regions, and then to mountain conifer forests, beech forests, and cold-adapted conifers at higher altitudes. Riparian forests develop near wetlands with particular ecological importance. Greek forests host rich biodiversity and provide essential ecosystem services, such as soil and water protection and climate regulation; oak forests play a particularly prominent role. Their conservation and sustainable management are necessary.
