"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.

The GBNERR tool loan program has been transferred to The Stewardship Network: New England (now called Nature Groupie). They have a very extensive collection of tools, including Weed Wrenches, as well as signs to help you direct volunteers for a workday. Please visit their website to get more information and to check out the tools. Good luck with your project!
