Soft moss
The Weichser Moos near Weichs is a nature reserve in the Upper Bavarian district of Dachau .
Geographical location
It is naturally located in the Danube-Isar hill country in the Glonn valley at an altitude of 461 m above sea level. NHN . The closest localities are northwest Weichs and northeast Ebersbach . It is bounded to the north by the state road St 2054 and to the south by the Glonn .
description
It is an extensive low moor or flatland moor that, in contrast to the raised bog, feeds its water from the ground. It can be seen as a wet biotope with standing water on soaked meadows. According to the protection ordinance of October 2nd, 1998 of the government of Upper Bavaria, it was declared a nature reserve because it is a designated fen with animals and plant species that are worth protecting.
Contrary to its name, the Weichser Moos is not a green moss area, but a flat moor with an area of 55.48 hectares , which is interspersed with nutrient-rich groundwater up to the surface. As a low moor, it forms in a so-called river valley along the nearby Glonn, which rises west of Odelzhausen and runs through the district of Dachau, to flow into the Amper in Allershausen, 15 km away . Geographically, it extends between the eastern end of the village of Weichs, Lkr. Dachau and Ebersbach, bounded by the Glonn river on the southern side.
Flora and fauna
The Weichser Moos is an FFH (Flora-Fauna-Habitat), which has been designated as such by the European Union and is therefore particularly worthy of protection because it forms a valuable, irreplaceable habitat for rare animal and plant species.
The vegetation of the lowland moor is rich in species. So you can find marsh meadows and litter meadows with pipe grass , lean flatland hay meadows characterize the image of the Weichser Moos. It can have a varied tree population and, as usual in bog forests, many bog birch , bog spruce and bog pines ( Spirke ). Among the lower shrubs there are many so-called dwarf shrubs, such as the bog berry, the rosemary heather, and also the rare, bay leaf-like gale shrub , which used to be used as an addition in breweries (so-called gagel beer). From a distance you can see a very moist high herbaceous area with willow and buckthorn bushes that lean to one side in the wind. Not to be overlooked are the great sedge meadows and meadows, which are usually found ideal growth conditions in bogs.
The Weichser Moos is a popular nesting place for gray geese and larks, all of which live there in large numbers. But deer also find their territory in the undergrowth and feed on grass, shoots and forest fruits. Among insects there are also the light and dark blue anthers, which are a type of butterfly, as well as white flies and the peacock's eye. The protected narrow diaper snail (lat. 'Pupillidae') can be found on the ground.
At some times, however, cormorants circling above the Weichser Moos, as they find rich prey as fishermen. However, they are not specifically mentioned by the State Office for Bird Protection in order to protect them from visitors and hunters.
Peat extraction
The bottom of the Weichser Moos was once removed by peat cutters for use as fuel, so there are still peat huts. Peat is a brown-black mixture of dead, decomposed plants. A fen is rich in moisture. This prevents the decomposition of the organic substances because of the permanent soaking, so that this biological process is strongly inhibited. The organic substances consist of several layers of differently decomposed, often fine-substance, brown-black peat layers (= humus form) over Mudde (term for muddy sediments). Today the extraction of peat serves more as a substrate for mud baths and for the production of garden soil (e.g. as peat mud). However, for nature conservation reasons, this can no longer be used economically here, as it contributes to the drainage of the moor and thus to its destruction.
