Attribute	Attribute Levels
Length of the river section that would be restored	0 km,^{^a} 0.5 km, 1 km, 2 km
Walking along the river	Yes, No^{^a}
Swimming in the river	Yes, No^{^a}
Barbecuing on the river bank	Yes, No^{^a}
Biodiversity	Low (60% of potential plant and animal species present)^{^a}
	Medium (75% of potential plant and animal species present)
	High (100% of potential plant and animal species present)
Price (increase in canton taxes per person per year)	0 CHF,^{^a} 25 CHF, 50 CHF, 100 CHF, 150 CHF, 250 CHF, 500 CHF
