What can you do?
Control of buckthorn is best achieved with early and frequent identification and removal of isolated plants before they begin to produce fruit. Established stems will need to be cut and chemically treated. Herbicide treatments are Glyphosate (Round-up), Triclopyr (Garlon 4) and 2,4-D, which provide excellent control when used properly.
In general, the best time to treat buckthorn is in the mid to late autumn. This plant retains its leaves much later into the fall than other plants. There are three common methods for applying herbicides: cut stump, basal bark, and foliar sprays.
Both buckthorn and garlic mustard have drastically dictated how we manage our forests. Garlic mustard, for instance, had made summer logging unacceptable due to spread of seed. Dollars must be set aside to combat these invasive species or we lose our forests.
Educate your neighbors of the drastic effects of invasive species. I cannot stress the importance of early detection and treatment. For more information, see your local department of natural resources.
This is a long term battle which must be fought yearly. Good Luck!
