Yellow dune
From Biocrawler, the free encyclopedia.
Yellow dunes are the dunes that are created after the first set of embryo dunes appear.
The yellow dunes average at about 5m and the soil to sand ratio is small on the soil side (hence yellow dunes).
The percentage of exposed sand on these dunes is generally about 20%. The 80% left 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.
