Adirondack invasive program focuses on knotweed

Each summer, the Adirondack Park Invasive Plant Program (APIPP) receives calls from landowners across the Park who want to know how to manage invasive species on their property. The most common question is, “how do I manage that ‘bamboo’?” Most often the plant in question is not bamboo, it is one of three species of knotweed that grow in the Adirondacks. 

To help community members learn how to identify these destructive invasive plants, prevent their spread, and manage infestations on their property, APIPP is hosting a free virtual learning event on Thursday, July 30 at 10 am. Visit to RSVP.

APIPP also has a wealth of information about how to manage knotweed and other invasive plants on its website. 

APIPP’s knotweed treatment efforts will expand this year in a pilot collaboration with the former Regional Inlet Invasive Plant Program (RIIPP), founded by Inlet property owner, Douglas Johnson. RIIPP was previously administered by the Town of Inlet, and then by the Hamilton County Soil and Water Conservation District (District). The program grew beyond the District’s boundaries and was transferred to APIPP this summer. APIPP was able to assume oversight of the program because of the assistance provided by volunteer invasive plant coordinators. The coordinators identify areas with knotweed and seek landowner permission to manage the sites. APIPP then contracts with licensed applicators to treat the plants with herbicides.

    As a retired biologist and Natural Resources manager I applaud all efforts to prevent, control, and eradicate invasive species. Knotweed is certainly high on the list. However, I wonder about the quality of the program and the real effort. Three years ago I reported several knotweed locations, one on my own property. Three years later still hasn’t been posted to the map/data base. Makes me doubt the worth of reporting.

    In the UK, if you have knotweed on your property and want to sell it, you must have the knotweed removed professionally and disposed of in a landfill.
    A law like that in New York would help force the knotweed eradication effort.
    Little Sandy Creek over by Lake Ontario is totally overwhelmed with knotweed. I am seeing some on the Bouquet river below E’Town. This would be a good place to eradicate because it spreads along the river banks with high water breaking off stems. Unless it is eradicated, the river will become unrecognizable as an Adirondack stream.

    I am definitely interested in any program or information as I am overrun with knotweed at my house in Johnsburg

      Michael, I am a certified applicator and have the necessary tools to control knotweed. feel free to get a hold of us we are based in Warrensburg.
