Bommecketalmeans "stream surrounded by trees" - and that is exactly what a walk through the Bommecketaloffers: wild forests and lots of water.
Habitat for species from much higher altitudesThe
Bommecketal is the preferred habitat of species that depend on cool, very clean water with a high oxygen content. These are rare, often inconspicuous species such as brook snails and spring snails, alpine planarians and midges and their larvae or certain mosses associated with torrents. In the Bommecke and some spring streams, a rare crustose red algae forms extensive blood-red deposits on alternately moist rock. Due to the gorge-like character of the north-facing notch valley, species can be found that are normally only found at much higher altitudes. The valley has now become a refuge for a large number of montane species, and
the fire salamander is a characteristic animal with a year-round habitat there. Its larvae grow in the clear mountain waters. It hibernates in the old mine tunnels, as do several species of bats. Yellow shield fern and spotted fern typically grow on the rocky ledges. Habitat-typical bird species for the Bommecketal are the dipper and grey wagtail.
