Japanese Barberry (Berberis thunbergii) is now considered an invasive species in New Hampshire.
This Japanese Barberry still needs to be removed from the gardens at Distant Hill.

Many of the plants in the list below have been found growing in the forests and fields of Distant Hill. A few of the plants were planted by us before they were known to be invasive. We are removing them from the property as quickly as we can. Live and learn!

NRCS Invasive Plant Control Funding

In 2013, we received a grant from the USDA Natural Resource Conservation Service (NRCS) to remove invasive plants from our property. That spring and summer we mechanically removed hundreds of common and glossy buckthorn, autumn olive, oriental bittersweet, Japanese honeysuckle, and multiflora rose with a tractor and winch.

 

In the fall of 2014, we followed up the mechanical control of the previous year with chemical control, applying Roundup with two different applicators:

  • With a hand-held sprayer 
  • And with a Buckthorn Blaster.

The Buckthorn Blaster™ is an inexpensive hand-held, 4-ounce capacity herbicide applicator for cut-stump herbicide treatment of buckthorn and other undesirable stemmed plants. The replaceable foam applicator tip of the Buckthorn Blaster™ releases herbicide only when pressure is applied to freshly cut stumps. It uses a tiny amount of herbicide compared to spraying, allowing us to spend hours treating stumps without a refill. And it eliminates the "drift" hazard to humans and native plants associated with herbicide sprayers.

HIGHLY RECOMMENDED!

NOTE: The New Hampshire Guide to Upland Invasive Species is a great resource to help identify the invasive plants and insects of New England.
