There are many different types of stream within the National Park: Wild streams in narrow valleys with a rocky riverbed, and sedately flowing, winding meadow brooks in broader valleys with a gravelly, sandy bed.
Flowing bodies of water are part of the natural landscape and do not require any special care. However, in some places they have been altered by dams, pipelines or work on the banks. These impediments are being gradually removed as part of renaturation measures.
Many typical animals species, such as fish, dragonflies, water beetles and, above all, numerous stonefly, mayfly and caddis fly larvae, as well as characteristic shore plants and moss, live on the edge of the water and in the water itself.
The headwaters, from which the streams originate, are also vital habitats. You can find places in meadows or forests where the groundwater meets the surface in the form of seepage springs almost everywhere in the National Park. A number of characteristic flora and fauna can be found in the spring water, which always has the same temperature – these consistent conditions are vital to these flora and fauna.
