To visitors of Schwarzes Wasser it is obvious: The excavators and trucks have disappeared because the desludging of the water banks is finished now!
In former times, the heath mere has been known for its special plant association with the keystone species Luronium natans (floating water-plantain). Because of increasing silting, this marsh plant has almost completely vanished from the site. The recently completed measure shall break the negative trend and reactivate the germinable seeds, that are still in the ground.
Furthermore, two smaller water bodies have been excavated on a former bog site. They are expected to evolve into heath moors and provide spawning facilities for the keystone species Rana arvalis (moor frog).
