Emerald Ash Borer Quarantine Repealed
Effective October 1, 2018, the Michigan Department of Agriculture and Rural Development (MDARD) repeals its Emerald Ash Borer (EAB) Interior Quarantine. The tree-killing pest has been found in all but four of Michigan’s 83 counties.
“Enacted in 2002, Michigan’s quarantine helped to slow the spread of EAB giving communities, land owners and managers the time to plan ahead of an EAB infestation to ensure diversity of their tree landscape,” said Gina Alessandri, director of MDARD’s Pesticide and Plant Pest Management Division.
EAB was first identified in North America in southeast Michigan in 2002. Since then it has been detected in 35 states, the District of Columbia and five Canadian provinces and most likely came to the U.S. from Asia in solid wood packing materials.
Until now, Michigan’s interior quarantine regulated the movement of ash trees, ash logs, other ash tree parts and hardwood firewood from the Lower Peninsula into the Upper Peninsula, from the quarantined counties of the U.P. into the non-quarantined counties of the U.P., and from anywhere in Michigan to several Great Lakes islands.
The EAB interior quarantine meant businesses and individuals handling ash wood, untreated ash products and hardwood firewood had to sign agreements with MDARD on how they would reduce the risk of moving the pest into non-quarantined areas.
