"Weed Wrenches" are specialized tools used for manual removal of woody stemmed invasive plants such as glossy buckthorn, autumn olive, multiflora rose and honeysuckles. We have 26 available for free loan to conservation groups and community members.

Invasive plants frequently colonize areas of bare ground so, after any invasive plant removal is done, we encourage you to complete the restoration by establishing native plants. We have 23 "planting bars" available for loan to help with this activity. They are great for helping establish bare root seedlings.

All tools are housed at Great Bay Discovery Center in Greenland and are available on a first-come, first-served basis. To become eligible to use the tools, we ask that you complete a brief survey. This survey will help us learn more about invasive plants in New Hampshire's coastal watersheds and develop strategies to manage them most effectively.
