Au Sable River Property Owners Alliance

The Au Sable River Property Owners Alliance (ARPOA) is a Michigan nonprofit of riparian property owners founded to preserve, protect, and enhance the Au Sable River watershed's natural resources. Its work includes the Cedars for the Au Sable reforestation program (over 28,500 northern white cedar seedlings planted since 1997), invasive purple loosestrife removal since 2009, watershed health monitoring, and advocacy against projects that threaten the river's water quality and flow.
