Rare Plants of the Inland Dunes near Sandhausen
Biotop

Sandhausen is situated a few kilometres south of Heidelberg in the Upper Rhine Valley in a region of inland dunes. The inland dunes consist of sand deposited by the wind in former times, blown on from the gravel banks of river Rhine which then changed its course permanently. In the southern part of Sandhausen you can find nature reserve 'Duene Pferdstrieb' divided into two parts, separated by a road. The photo above shows the high open inland dune, which is surrounded by a fence. The relative steep slope and the flat area in front of it are originated by the former taking of sand. Many of the specific plants of this biotope, as Alyssum montanum subsp. gmelinii, Euphorbia seguieriana, Silene conica, Silene otites, Bassia laniflora, Odontites luteus, and specialized grasses are not only growing behind the fence. They can be seen directly at the roadside, where they partly have better conditions than behind the fence, because the rigidity of the sand surface caused by lichens and mosses is occasionally broken here by entering.
In the southern part of the nature reserve the open dune changes to pine wood.
 
In the northwestern part of Sandhausen near highway resting area Hardtwald there is nature reserve 'Pflege Schoenau - Galgenbuckel', which partly contains the same rare plants as nature reserve 'Duene Pferdstrieb'.

Naturally this list of plants isn't complete. It will be continued on occasion.
 
There are similar biotopes in the inland dunes south of Mannheim, on which pages with spring flowering plants and summer flowering plants are available.
Also on the inland dune biotope Viernheimer Heide there is a web site.
