The Ice Age is to blame ...
After the end of the last ice age about 10,000 years ago, had an entirely different appearance of the Lower than today. While came the Freezing even in northern Germany to a standstill, but even when we were changing climate and vegetation. The Lower Rhine had then similarity with today's Arctic tundra. When the ice age came to an end shaped extensive sandbanks gravel deposits and the landscape, creating in the melted water flowing out the bed of the Rhine today. The wind was the sand in the low vegetation Landscape move and rearrange. So it came to large sand mounds. the inland dunes. One of these dunes trains is now called Fluer Heath. As luck would have it, which in some places within the dunes have deposited a layer of water damming flood plain of the Rhine. It is this layer of clay put the wind again and blew out a hollow, by up to 7 meters high, crescent-shaped dunes, is surrounded. The well had no drainage, so the rain water is collected and developed in the otherwise dry dunes a standing waters. First plants settled soon and stopped with their roots firmly the sand of the dune and thus prevented that the basin was again blown.
Why does the water in the pond is so dark, almost black?
In the course of the degradation of plant debris was the coffee-brown color of the water. This reduction proceeds under certain conditions, not fully but only partially. The intermediates of this degradation include the so-called "humins. Acids with a yellow to dark brown in color. They enriched themselves, and dark brown colored water. As the saying made from this black, and the pond was his name.
The plant world.
The Waterlobelia, for example, was the kind, the black water had become famous in central europe as it was impossible to find even in 1923. To date, disappeared more than 60 other species, of which 37 typical representatives of nutrient waters and mires. As before, the black water home by many, some endangered plant species. Between rushes and sedges can be found in some places even the marsh.
Nutrient-poor sites such as wet heath and open peat soils are the places where the one Middle sundew, one of our few "carnivorous" plants found. To their nitrogen requirements cover, they may use animal protein. Small insects, spiders stay on the sticky Leaves lasting and are decomposed by the plant with specially produced digestive enzymes, then was added. A close relative of the middle sundew, round-leaved sundew is the also the to find black water. It grows, however, together with the very rare cranberry in Peergrass. There are a further number of endangered and rare plant species to be seen. It is definitely worth carefully to take a walk around the black water!
The animal world:
The animal kingdom it resides a number of peculiarities. Sun comes here from the Nationwide Endangered moor before. Remains hidden to most visitors of this frog, that he comes lay for a short time at the end of February or early March to waters to spawn. sinseine Then he leaves the waters again and it will soon be another frogs. The Frog Pond and the little forest frog. They keep most of the year on the water and croaking in contrast to its rare cousin, loud and persistent.
Noteworthy is the small creatures of the water. So here there are at least 23 species of dragonflies, including Nationwide also rare species such as white-faced darter and the spear Damselfly.
Over 1000 species of beetles have been identified so far. Including how large beetle: stag beetle pupae robbers and sawhorse. At least in name each of the ant lion is probably one term. The larva of the Neuroptera

For wildlife, the same applies as for the unique plant life on the Black Water, Take you some time and is with open eyes by nature, then there are so few and more to discover!
