What is a hind dune?

A hind dune, also known as a back dune, is a type of sand dune located inland from the primary dune line along a coastal area. It typically forms behind the foredunes, which are the first line of dunes directly facing the ocean. Hind dunes are often stabilized by vegetation and can support diverse ecosystems, serving as a buffer against wind and wave action. These dunes play a crucial role in coastal dynamics and habitat formation.
