The Sippenauer Moor is a nature reserve and an FFH area in the Mitterfecking district in the municipality of Saal an der Donau in the Lower Bavarian district of Kelheim. It is located southeast of the Saaler district Mitterfecking and west of the Hausener district Sippenau.

Location and nature

The Sippenauer Moor is located in a valley cut through which the Danube flowed in earlier times and which today leads to the Feckinger Bach , which flows into the Danube ( throughflow moor ). At the southern edge of the moor runs a border of the White Jura with characteristic Malm limestone . At this point, karst springs are increasingly forming , which feed the moor. The escaping groundwater is very sulphurous . The biotope is divided into the so-called old area of about 1.35 ha in the northwest of the moor, whose peat body comes from the end of the last Ice Age , and the younger areas of about 15.9 ha, which are characterized by loess drifts . These promote the formation of low peat peat, while low peat peat is formed in the area of the old area by the incoming karst water.

The sulfur springs in the moor represent a special feature in the entire Bavarian region. The origin of the sulfur it contains is unclear. It is assumed, among other things, that it comes from lignite deposits of the Tertiary in the Alpine foothills or from pyrite nodules in the adjacent Malm Limestone. The age of the sulphurous waters in this area is estimated to be 8,000 to 20,000 years.

The name of the moor is derived from the sulfur springs: clinging means “stink” or “foul smell”.

history

The area of the moor was settled as early as the High Middle Ages , as evidenced by numerous landscape features such as ramparts and moats. There are also references to a medieval castle stables .

At the beginning of the 20th century they wanted to use the sulfur springs of the moor for a spa, but this would have meant the destruction of the moor. That is why the Regensburg Botanical Society (RBG) began buying up the first areas in the old area in 1911, and in 1939 it was declared a nature reserve. Since then, there has been a route requirement in the publicly accessible area . By 2003, the RBG increased its property in the area of the Sippenauer Moor to 15.9 hectares.

Endangerment and care

The biotope is most acutely endangered by the pumping of groundwater through the lime works in Saal an der Donau in a quarry approx. 1.5 km away . Investigations showed that during the period of pumping (1977–1985 and from 1996) the water levels of the bog developed critically, which particularly threatened the sensitive old area. As a result, there was a legal dispute between the lime works in Saal an der Donau and the RBG, which dealt with the use of groundwater in the vicinity of the moor. It ended in May 2001 with a settlement by the Bavarian Administrative Court, which precisely laid down the extent of pumping and the financial distribution of compensatory measures.

The maintenance and preservation measures decided in the course of this comparison include the expansion of the spring stream and a groundwater balance between the old area and the surrounding areas. One third of the costs for these measures are borne by the RBG. In 2003, the responsible district office in Kelheim acquired an adjoining forest area of 8.4 hectares, which was transferred to the RBG and which almost doubled the existing properties. However, the RBG criticized the fact that these measures to maintain the moor were inadequate. In order to maintain the characteristic state of the moor, forestry measures and regular mowing of the moor meadows are also carried out.

The maintenance measures are regulated until 2010, after which a new regulation must be negotiated.

Flora and fauna

The Sippenauer Moor offers a habitat for numerous rare species, some of which are only found here. In addition to various plant species, a previously unknown family of archaea , so-called cold archaea , was discovered here in 2002 , which live in symbiosis with the thiotrix sulfur bacteria from the karst springs . Native are:

insects

Striped swell maiden

plants

Archaea

March cup colonies

Particularly impressive are the large numbers of March cup colonies (" spring knot flower ") in the alder break of the brook at the entrance to the nature reserve.

Geotope

The Sippenauer Moor has been designated as a valuable geotope (geotope number: 273R007) and natural monument by the Bavarian State Office for the Environment .
