Delver Koog

The nature reserve is distinguished by areas of fen with reed beds and meadows of large and small sedge.

The many, small, open waterbodies with an extensive irrigation ditch system form an important habitat, especially for birds.

At that time, there was a saying :Wenn Du wullt warrn in't Bett ni natt, denn kumm nan'n Delv un koop Di Dack!

Extensive areas of reedbed and rare plants such as cottongrass and various species of sedge exist.

The Delver Koog is one of the most important stopover sites for the hen harrier, as well as waders, gulls, and wet meadow birds that rest here during their migration.
