Many reeds have disappeared along the Ems as a result of digging, straightening, and bank reinforcement. These reed belts, which appear plain at first glance because of the lack of plant variety, are actually a diverse habitat and also contribute to the self-cleaning processes of bodies of water. The Master Plan Ems 2050's list of measures includes a number of measures for reestablishing reed zones. They are expected to be established in the planned tidal polders and the river neck in Rysum, where existing reed belts should also be preserved.

Reed zones are especially crucial to bird species who specialise in living and breeding in this habitat, including reed warblers, rails, and reed buntings. Many fish and amphibians also spawn here, and their offspring have enough room to grow. Many invertebrates also call this habitat home.
