Green is not always green. Wet meadows have different grasses and herbs than so-called fresh meadows.
At this point, scientists have put pipes in the ground. They can use them to measure the water level in the ground and research the plants and habitat here. It is also advantageous for farmers to know where the water is close to the surface. Because then they will harvest different grasses than elsewhere and they cannot drive heavy machinery onto the ground, otherwise they will get stuck.
You can find several different grasses here. You can recognize them not only by their color, but also by the shape of the stalks. Some are angular and rough, some are round and smooth. Take a close look and feel! But be careful, some can also cut you!
There are sweet grasses, which include reeds. Then there are sour or sedge grasses, so-called sedges. They usually have folded, rough leaves and other inflorescences like reeds. The shore sedge also occurs here in this depression. A rush also grows in many clumps here. These do not have stems with leaves, but the shoots are round and have everything in one: stems with leaf color and flowers. What is special is that they also live in wet soil, where many grasses cannot survive. Cut off a stalk of the rush; there is a spongy tissue on it. This allows them to bring air into their roots. If you use a magnifying glass, you can take a close look at the differences between reed, sedge and rush flowers and leaves.
