Picking our Battles:
Enhancing Success of Invasive Plant Control Projects

Invasive plants can cause significant ecological and economic harm and are changing the face of America. They may impact wildlife by choking out natural habitats such as freshwater wetlands, causing loss of available food, or altering habitat structure.

Sample resource map

The importance of minimizing the spread of invasive plants across the landscape means they are a common focus of restoration projects. However, invasive plants know no boundaries and can easily reestablish from surrounding areas unless a landscape-scale strategic approach is taken to prioritizing control projects.

The New Hampshire Fish and Game Department and the N.H. Natural Heritage have teamed up with over 120 community members, natural resource managers and academics to develop a statewide strategic prioritization plan for the control of upland, wetland, and intertidal invasive plant species.

Only by working together on shared invasive plant “battles” across differing land ownerships and political boundaries, can we effectively protect our native plants and wildlife habitat in the long term. Thanks for being part of the team!

Customized Maps

Click on a town name below download a customized map for each New Hampshire town, showing priority areas where invasive plants removal will have the most immediate impact and most effectively protect our native natural resources in the long-term. You'll also find a customized “early detection” list of plant species just coming into each town and a “watch list” of plant species that are not present yet, but are lurking close by. These documents describe how to use this strategy to prioritize projects right down to the individual property or stand level; you'll also be able to see how the statewide model was developed.
