Sand dune ecology describes the biological and physico-chemical interactions that are a characteristic of sand dunes. Sand dune systems are excellent places for biodiversity, partly because they are not very productive for agriculture, and partly because disturbed, stressful, and stable habitats are present in proximity to each other.
Blowout located 6.5 km south of Earth, Texas (1996). Blowouts are sandy depressions in a sand dune ecosystem caused by the removal of sediments by wind.. Commonly found in coastal settings and margins of arid areas, blowouts tend to form when wind erodes patches of bare sand on stabilized vegetated dunes.
The shingle, strandline and sand-dune communities consist of a single community found on coastal shingle , two communities associated with strandlines (SD2 and SD3), and sixteen sand-dune communities. The sand-dune communities fall into the following four groups: six foredune and mobile dune communities (SD4, SD5, SD6, SD7, SD10 and SD19)
Ammophila breviligulata (American beachgrass or American marram grass) is a species of grass native to eastern North America, where it grows on sand dunes along the Atlantic Ocean and Great Lakes coasts. Beachgrass thrives under conditions of shifting sand, sand burial, and high winds; it is a dune-building grass that builds the first line of ...
The Physics of Blown Sand and Desert Dunes is a scientific book written by Ralph A. Bagnold. [1] The book laid the foundations of the scientific investigation of the transport of sand by wind. [ 2 ] It also discusses the formation and movement of sand dunes in the Libyan Desert .
Native to southern Africa, it grows on coastal and estuarine sand dunes in Namibia and the Cape Provinces of South Africa. The plant is edible and is a local delicacy in its native southern Africa, where it is known as "dune spinach". It is an important component of dune vegetation, being a hardy pioneer and stabilising dunes.
Spinifex is a genus of perennial coastal plants in the grass family. [2] [3] [4] [5]They are one of the most common plants that grow in sand dunes along the coasts of Africa, Middle East, Asia, Australia, New Zealand, and New Caledonia, with the ranges of some species extending north and west along the coasts of Asia as far as India and Japan.

Psammosere's literal meaning is “originating on sand". It was named by Frederic E. Clements who described the sequence in Plant Succession 1916, [3] although it had also been observed by Henry Chandler Cowles after he conducted several studies on the sand dunes surrounding Lake Michigan, which was influenced by the work of Eugenius Warming.
