海岸沙丘分布在法国西部布列塔尼周围的许多地方，最大的沙丘带位于洛里昂公路基地和基伯隆半岛之间的南部。它们的初步构造开始于青铜时代（±2400 BP）之后全新世海侵中断的轻微回归期间。直到18世纪，它们一直在当地被喂养，但现在不再建造新的沙丘，除了在Audierne湾发现的一个例子，以及在风的作用下在海滩山脊上喂养，例如在Goulven， Pays de Leon，这并没有导致真正的风成沙丘的形成。第二次世界大战后，沿海旅游和城市化对这些沙丘带造成了威胁。对自然保护感兴趣的科学家和积极分子团体向市镇委员会和土木工程师提供有关沙丘退化和管理的资料。在法国环境部的帮助下，情况逐渐得到改善。在过去的几十年里，许多地区受到沙丘保护过程的保护，但没有阻止人们进入海滩。然而，对受保护或恢复的沙丘的管理方式仍然是一个讨论的问题。
Coastal dunes are scattered in many places around Brittany, Western France, the largest dune belt being found in the south between Lorient Roadstead and the Quiberon Peninsula. Their primary construction was initiated during a slight regression interrupting the Holocene transgression just after the Bronze Age (± 2400 BP). They continued to be locally fed until the 18th Century, but at present time new dunes are no longer built, except for a case found in the Bay of Audierne, and for the feeding in situ of beach ridges by wind, e.g. at Goulven, Pays de Leon, which does not lead to edification of real eolian dunes. Following the Second World War, coastal tourism and urbanization have threatened these dune belts. Scientists and activist groups interested in nature conservancy have approached commune councils and civil engineers with information concerning dune degradation and management. With the help of the French Ministry for Environment, the situation has been gradually improved. During the past decades, many areas have been protected by processes of dune preservation without preventing access to beaches. The type of management of the protected or restored dune remains, however, a matter of discussion.
