Dünenlagen

Dünenlagen refers to areas characterized by the presence of sand dunes. These landscapes are dynamic and are primarily formed by the action of wind, which transports and deposits sand. Dünenlagen can be found in various coastal and arid regions around the world. The formation and stability of dunes are influenced by factors such as sand supply, wind velocity, and vegetation cover.

Coastal dünenlagen are typically found along shorelines where waves deposit sand, which is then moved inland by prevailing winds. These dunes often play a crucial role in coastal protection, acting as natural barriers against erosion and storm surges. Vegetation, such as marram grass, is vital in stabilizing dunes by anchoring the sand with its root systems. This vegetation helps to trap sand and build up the dune structure.

Inland dünenlagen, also known as sand seas or ergs, are less common and are usually found in desert environments. These areas can be vast and feature complex dune formations like linear, barchan, and star dunes, each shaped by specific wind patterns. The ecology of dünenlagen can be specialized, with flora and fauna adapted to the harsh conditions of low water availability and shifting sands. Conservation efforts often focus on protecting these unique habitats from human activities that can lead to dune degradation.
