Sand dune stabilization is a coastal management practice designed to prevent erosion of sand dunes. Sand dunes are common features of shoreline and desert environments. Dunes provide habitat for highly specialized plants and animals, including rare and endangered species .
Psammosere succession is also extremely vulnerable to human activities. At beaches, footpaths over dunes will trample grass, creating exposed sand. This exposed sand can be blown away very easily, leading to the roots becoming exposed and neighbouring plants dying. This creates blowouts, which can set back psammosere succession. [8]
An example may be in a beach dune system where the impact of the human race has caused footpath erosion to occur, affecting the vegetation so that feet trampling on the dune plants eventually destroys them. The uplands of Northern England were once covered by deciduous woodland. Some heather would have been present, but in relatively small amounts.
Sand dunes are vulnerable to human activities. Therefore, they need as little human interaction as possible for their protection. Human coastal activities has led to the erosion and loss of plant life on sand dunes. [19] Plant life has been established as an important stabilizing factor of sand dunes and the loss of it will cause more erosion.
Although the Gobi Desert itself is still a distance away from Beijing, reports from field studies state there are large sand dunes forming only 70 km (43.5 mi) outside the city. [59] [60] In Mongolia, around 90% of grassland is considered vulnerable to desertification by the UN. An estimated 13% of desertification in Mongolia is caused by ...
The Great Sand Dunes National Park has the highest sand dunes in North America. There are 30 square miles of dune field with five massive dunes – the tallest being 750 feet.
Beaches can erode naturally or due to human impact (beach theft/sand mining). [9] Erosion is a natural response to storm activity. During storms, sand from the visible beach submerges to form sand bars that protect the beach. Submersion is only part of the cycle.
On a recent afternoon, Justin LeClaire, an avian conservation biologist with the environmental advocacy group Coastal Bend Bays and Estuaries, plodded through the sand dunes just north of the ...
