Japanese Knotweed Treatment Seminar

Japanese Knotweed Treatment Seminar 2021-10

Japanese Knotweed, a non-native invasive plant that spreads aggressively,  degrades property values as much as it degrades native ecosystems.  Forming a ten-foot tall ever-spreading  mass, Fallopia japonica prevents native plants from growing, yet provides little to no benefit to wildlife.  Japanese Knotweed is difficult to dissuade, let alone eradicate.  Yet hope remains – learn what to do, and when to do it, at our first Japanese Knotweed Treatment Seminar:

Why it’s imperative to control Japanese Knotweed

Like other aggressive invasive plants, Japanese Knotweed must be actively managed.  Japanese Knotweed quickly forms a monoculture, reducing biological diversity and lowering the quality of our streams and rivers.  Once Japanese Knotweed establishes itself, habitat degrades in quality, streambanks erode, and species diversity declines. 

Once well established, control requires a well-timed plan of annual treatments for up to five years.  If control is not attempted, Japanese Knotweed will spread to the exclusion of all other species. 

Japanese Knotweed – Landowner Assistance Project

One landowner, working alone, contributes to the health of the ecosystem by combatting invasive plant species – but neighbors working together, and combining efforts with environmental and municipal entities, can accomplish massive improvements.  The CFC will coordinate a several-years’ program to connect parcels together, and to advocate for and assist with control treatments.  This October’s Japanese Knotweed Treatment Seminar is the first step to improving the health of our Wild & Scenic Clarion River. 

Landowner Participants benefit from: 

  • expert information and guidance, including creation of a treatment plan, and recommendations on chemical formulations;
  •  access to high-quality equipment, or the option to hire vegetation management contractors in a block;
  • help monitoring progress and reporting local infestations; and
  • advice on re-establishing native habitat

Please join us for this first round meeting – and bring a neighbor!
