The content of the project is the natural design of the approximately 2 000 m long seaside shoreline of the Lietzense in accordance with the garden monument conservation requirements. The nature-oriented design increases biodiversity, supports the ecological balance of the lake, sustainably promotes good water quality and thus significantly increases the quality of stay in the park. The shore restoration of the Lietzense is carried out with planted filter boxes (geophytofilters), which additionally allow a nutrient retention from the water body.
