Plants of the Reiss-Insel at Mannheim


The 'Reiss-Island' is a natural habitat and recreation area near Mannheim with riparian woods and orchards, situated south of the city in a dead branch of river Rhine. In 1916 the owner Carl Reiss donated it to the City of Mannheim. Condition was that the natural condition has to be maintained. In 1950 it became a nature reserve. There is a circular route of 4 km length, but the Reiss-Insel is closed during the bird breeding season from March to including June. The old Silver Willows are slowly pushed away by the Ash-Leaf Elder, which was introduced from North America and which grows faster.

Later in the year the areas of the riparian woods, which sporadically are flooded, are covered by the nettle:

Coincya monensis subsp. cheiranthos / Wallflower Cabbage Brassicaceae / Crucifers Only once, in the year 2006, I found one specimen of Wallflower Cabbage Coincya monensis subsp. cheiranthos at the circular route. Most probably the seed has been washed ashore by a flood of the rhine.
The old fruit trees in the orchards are a refuge for birds and many other animals.
