Plants of the Inland Dunes south of Mannheim in Spring
The inland dune areas 'Unterer Dossenwald' and 'Hirschacker' are situated between Mannheim-Rheinau, Mannheim-Friedrichsfeld and Schwetzingen. Moreover the area of the Rheinau Lake, which is completely surrounded by buildings, is a valuable inland dune biotope. The inland dunes are wind-borne sand fields which came into being, when at the end of the ice age strong winds blew sand out of the gravel, which the then still meandering Rhine carried from the Alpes and deposited at its edges. Since there are extreme conditions of the environment, for example dryness and high temperature of the soil, special plant communities have developed here.

There is also a page on summer flowering plants in the same area.
 
The pages on Nature Reserves near Sandhausen and the Viernheimer Heide deal with the flora of inland dunes, too.
