The Endangerment & Conservation of the Western Marsh Orchids

The range extends in Europe from the Pyrenees to the Baltic and to the Don, possible even to the Volga. The western marsh orchid is not found south of the Alps and is rare in southern Scandinavia.

In Germany the western marsh orchid is widespread but with several gaps. In many places, especially from western to northern Germany, it is extinct.

In Switzerland the western marsh orchid is also quite widespread. A significant gap is found south of the Aar between Aarau and Lake Neuchâtel.

Although the western marsh orchid is commonly found in some regions, it is nevertheless protected as an orchid.

As with many marsh plants, the numbers of this species have been dwindling for quite some time. The main causes are the entry of nitrogen via fertilizer, drying out of the habitat, and intensive conversion to pasture. The western marsh orchid does not react so sensitively to changes in its habitat as for example the early marsh orchid. It is usually the last of the native orchids to disappear. This tolerance makes it a still relatively common species.
