Plants of the Inland Dunes south of Mannheim in Summer
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 during the ice ages strong winds blew sand out of the gravel, which the then still meandering Rhine carried from the Alpes and deposited at its edges. The inland dunes came into being when at the end of the ice ages 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 very high soil temperatures of up to 70 degrees celsius in summer, special communities of plants have formed here.

Also the fauna of the inland dunes is highly specialised: for example the Sand Wasp Bembix rostrata (left) which digs a subway up to 20 centimeters deep for every egg and supplies the offspring with paralysed insects, or the Northern Dune Tiger Beetle Cicindela hybrida (right) which is walking jerkily and which is eating other insects.

Naturally this list isn't complete. It will be continued on occasion.
 
There is also a page on spring 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.
