Yellow dune

Yellow dune

Yellow dunes are sand dunes that develop after the first set of embryo dunes appear. With an average depth of about 5m, with a soil to sand ratio that is small on the soil side (hence yellow dunes).

The percentage of exposed sand on these dunes is generally about 20%. The remaining 80% is covered with vegetation that cannot withstand the conditions on the embryo dunes. The plants on these dunes can withstand the slightly alkaline sand an example of the plants would be marram grass "spinifex."

The moisture content of these dunes is relatively low so the plants still have very strong root structure and are capable of getting every drop of water that comes their way.
