Freshwater ecosystems in the Swiss plateau are threatened by multiple stressors that deteriorate water quality and hydromorphology. This is the result of channelization, dams, wastewater, and agriculture, among other causes. To restore these ecosystems and stop the biodiversity decline, multiple management measures will be implemented over the next decades. We propose methods for prioritising the location and timing of restoration measures to maximise their effectiveness, considering many sectors and multiple societal objectives.More
Persina Nature Park has high conservation value but is also of importance to local economies through its fish resources, climate regulation and biomass production. However, the societal, economic and environmental value of this wetland is not well recognized by local and national stakeholders and decision-makers.
