Courtesy boat inspections are the cornerstone of the state's invasive aquatic species prevention program. Limited funds are available for locally initiated CBI programs. Grants up to $2000 are available to municipal and county governments, quasi-municipal organizations (including water districts) and 501C(3) eligible organizations such as lake associations. The State of Maine also uses a Request for Proposal (RFP) process to solicit applications for plant control work.

To reduce the spread of aquatic invasive species in Maine, a law was passed by the Maine Legislature (effective June 16, 2023) that requires boaters to take specific actions to encourage water to drain from their watercraft prior to entering a water body or leaving a launch site. Aquatic invasive species are any fish, wildlife, or plant species that spreads to a water body where they do not naturally occur. These species are often transferred to new locations on watercraft, watercraft trailers, and other equipment associated with water recreation, and they impact the health of our waters, fish, and wildlife.

How can an insect that is smaller than a penny cause so much ecological, economic, and cultural devastation? The emerald ash borer, an invasive beetle native to Asia, is one of the most destructive invasive species in North America. These tiny pests killed tens of millions of ash trees in the northeast – and continue to this day.

In Maine, a coalition of Indigenous and non-Indigenous researchers, tribal members, state and federal foresters, conservation groups, and local communities have been working for the past twenty years to prepare for the onset of emerald ash borer in northeastern forests. The group, called the Ash Protection Collaboration Across Wabanakik, is focused on identifying research-informed strategies to protect the future of ash trees.
