Small tunnel excavator under the crassach river

The short course of the small river krassach resembles an idyll. Originating in the picturesque barental, it flows gently splashing towards the town of the same name, through this further in the direction of niesten and to suden. After 300 meters the creek has grown to a width of four meters and ends with a dam that is about six meters wide and certainly has a water depth of up to 1.50 meters. Behind it, the water drops again at this depth. A beaver has obviously settled in this place.

Not only there the hardworking rodent was very active. The beaver has dug a rough pipe tunnel coming from the river into the rapsfeld 50 meters next to it, through which a child could certainly fit, michael schmittlein from the city’s building department noted with astonishment during a site visit. When working in the fields, this underground passage can be very dangerous for the farmer, says farmer and city councilor norbert rehe (GUB). The beaver does not belong here, he thinks, because the amount of small fish living in the river krassach has decreased noticeably in the meantime.

Beavers find their way back to the region

BBV district chairman michael bienlein can only agree with this. An almost extinct rodent can be found again more often, but the population of other animals is decreasing strongly. If man intervenes, there will always be advantages and disadvantages in nature. But limits had to be set here, he says.

The protected rodents are since the beginning of the 2000s also in the local region again native. For about a hundred years, beavers were almost extinct in bavaria; their fur and meat were too coveted. The district office’s beaver advisor, hans-werner herold, says there are problems with the rodent throughout the district, especially on smaller streams and rivers. Territorial spaces at dredging lakes and at the main are already occupied by beavers. Beavers that want their own territory have to search until they find a habitat that is comfortable for them.

Keeping the balance

70 beaver territories currently exist in the district of lichtenfels. The stock keeps reducing itself. After two years, the offspring is mercilessly sent by the parents into a struggle for survival. He may then not continue to stay in his ancestral home. But a beaver that even swims through already occupied terrain is attacked by others. In the adjacent wooded areas near the water, foxes are the only natural enemies for young beavers.

Releasing beavers for shooting, as often demanded, would not be a solution either, the expert advisor notes. Because when a beaver is no longer in its territory, it is quickly reoccupied by another one.

The dammed-up crassach in connection with the undercut field is a nuisance from the farmers’ point of view and also a danger for agricultural equipment and its operators, not least because of the depth of the dug holes, says mayor michael zapf (GUB). From the point of view of species protection, the beaver seems to feel very much at home here, if you look at the area in front of kleinziegenfeld in addition to krassach, for example. But despite all the sympathy for the beaver, it is necessary to take countermeasures with justifiable means, so that a balance in nature is maintained.

A compromise is the goal

The participants agreed that language must be sought, the result of which satisfies all. The coarse beaver pipes should be filled and the drainage installation of the beaver at the dam should be lowered. But first it is necessary to determine the cost of it. So it is highly probable that there will be a beaver in krassach in the future as well.
