Bordering the North Sea between France and the Netherlands, Belgium is made up of flat coastal plains in the northwest, rolling hills in the central areas and the mountains of the Ardennes in the southeast. Animals still living in Belgium’s beech and oak forests include boar, fox, badger, squirrel, weasel, marten and hedgehog. A number of birds can be found in the Belgian lowlands, including sandpipers, woodcocks, snipes and lapwings. Porpoises, seals and whales can be spotted in the waters off the northern coast.
The Scheldt and Meuse are the country’s longest rivers. Flooding is a threat along the rivers and in areas of reclaimed coastal land, which are protected from the sea by concrete dikes. Other environmental problems facing include air and water pollution from industry and agriculture.
