During the extension and modernisation of the clinic from 2015 to 2019, the biotope was also optimised. This natural site fits into the surroundings beautifully and invites patients, relatives, members of staff and visitors to observe fauna and flora.
The biotope, which is located between the hospital building and the Ring of Life landmark, can be seen from the clinic's Restaurant Centro and from the patient rooms. The water area is 900 m2 and, at a depth of at most 150 cm, holds about 500,000 litres of water. The biotope is only fed by precipitation. This results in natural water level fluctuations.
The oasis offers living space and breeding opportunities for various animals: frogs, dragon flies, water snails, newts and birds. The flora in and around the biotope is also diverse: reeds, water lilies, marsh spurges, bulrushes, irises, willows, back alders, and sedges, surrounded by untouched flowering meadows.
