Which features characterize the northern part of Lower Saxony?

The northern part of Lower Saxony is characterized by the following features:

• Landscape and Terrain: The region is dominated by the North German Plain, consisting largely of sandy lowlands featuring heath, bog, and polder, interspersed with scattered forests.1
• Coastal Geography: In the northwest, the Frisian Islands lie in the North Sea. Significant portions of the coastal land sit below sea level and are protected by dikes. The Wadden Sea tidal-flat region, a World Heritage site, protects fragile ecosystems along the coast.12
• Agriculture and Economy: Fertile marshes at the mouths of rivers like the Weser River primarily support a pasture economy. In contrast, the northeastern region contains the Lüneburg Heath, which is less fertile and known for its traditional red farmhouses and ancient megalithic structures.1
• Population: Compared to the south-central belt of the state, the sandy lowlands of the north are sparsely populated.1
