Landlocked Hungary lies in the central Danube Basin and is divided into three major geographic areas: the Great Plains in the central and eastern part of the country; the Transdanube, a hilly region lying west of the Danube River and extending to the Austrian foothills of the Alps; and the Northern Hills, a mountainous region beyond the northern boundary of the Great Hungarian Plain.
For a small country, Hungary is rich in biodiversity and is home to such species as: roe deer, wild boar, fox, mouflon, imperial eagle and great bustard. The Great Plain region is an important breeding ground and migration stop for a number of migratory bird species.
Air and water pollution are some of Hungary’s most serious environmental problems. Water quality in the Hungarian part of the Danube has improved over the years but is still plagued by pollutants from industry and large-scale agriculture.
