"An absolute rarity and an absolute stroke of luck to find this species once in a lifetime. The species makes the natural monument wetland at bieberbach something very special!" This is what alexander ulmer wrote to his colleagues in may 2016. What so excited the managing director at the landesbund fur vogelschutz (LBV) in coburg was a small fern: the nattern’s tongue.
Botanists had been searching for a long time for the plant, which was last confirmed as a find in the 1980s. Alexander ulmer was all the more pleased that the nattern’s tongue was discovered in the area with a considerable number of specimens.
Frank reibenweber, managing director of the landscape conservation association (LPV) coburger land, explains why the area was given the status of a natural monument: "when the area was placed under protection, the status of a protected landscape element did not yet exist, which is applied today."
The value of the site on the western edge of sonnefeld was recognized as early as the 1970s. The bypass road was therefore placed closer to the site than originally planned. Separated from the village by the strabe dam, the area continued to develop in a positive way. But now it is in danger. "Last summer, you could walk through the middle of the pond in half shoes", says frank reibenweber. Now the thorny stalks of loosestrife stand out there. But there is also again a water flat to recognize.
Drought as an amphibian killer
They are obviously pleased with a larger community of frogs, who let a loud concert be heard – as if they had to croak for fellow species that have fallen victim to the drought. "We are registering on the amphibian fences that we probably lost a third to a half of the population of amphibians last year due to the drought.", frank reibenweber describes the ausmab of the losses. If summers like this were to come more often, it could mean the end of the sedge meadow near sonnefeld in the long term. Coot, moorhen and teal, which occur here, have disappeared from this habitat.
The hollow through which the beaver brook flows has become a floodplain forest in this area, through which a narrow fub path winds – a piece of rustic nature right at the gates of the community. Now, after the rainy may, the creek carries plenty of water, the wetlands are really wet and plants and animals seem to really enjoy it.
Designed and developed
Even closer to the town, near the access road to sonnefeld coming from bieberbach, are flat areas that were shaped years ago by the landscape conservation association. "This is now about 20 years ago and has developed quite well", frank reibenweber is pleased. Hedges planted at that time have grown high and dense. Fruit trees form a meadow orchard. Only a few that were planted at the time have perished.
The meadows, which largely belong to the municipality of sonnefeld, are extensively farmed and mowed late accordingly. The grass is used and therefore removed. The plants do not get manure. "Nevertheless, it takes a long time for the soil to become nutrient poor", says frank reibenweber. But the depletion would have been an important prerequisite to get the diversity of plant species that conservationists want for such flatlands.
An insect wall was erected in a protected corner of the hedge. During the inspection, frank reibenweber noticed that the area was pleasantly busy and that many of the artificially created pipes had been obtained from different species.
