The Barry County Board of Commissioners voted recently to allow the state to aid in eradication efforts starting today. The move gives DNR officials access to Barry County's lakes and other waterways to kill swans.
The DNR has said it wants to reduce the state's mute swan population from about 15,500 to fewer than 2,000 by 2030. It wasn't immediately known how many mute swans might be targeted in Barry County.
State officials say the birds are an invasive, non-native species with a destructively voracious appetite for vegetation. Mute swans have been in Michigan for about a century.
Opponents of the planned killings want nonlethal management options.
