Forest areas have expanded considerably since the 1990's in Greece. Some Greek forests have been included in the Natura 2000 network as areas with high biodiversity.

There are also different forests that are protected by Greek law, which are characterized - as a category - as National Woodland Parks, National Parks, Aesthetic Forests, Nature Reserve Areas and many more. These names typically mean that the forests are home to a rich botanical, ecological, aesthetical or historical and cultural value, which are protected by Greek legislation.

Greek ecosystems have adapted to dry, hot summers and cold winters. Oak trees have developed in the Mediterranean and Circum Mediterranean zone, while acorns grow in the Thessaly plain where the soil is more fertile.
