This month’s topis is  Untying the Knotweed Problem: 9-year Study of a Chemical-Free Approach by Sigrid Resh, Research Assistant Professor of Forest Ecology and Coordinator, Keweenaw Invasive Species Management Area (KISMA)

Invasive knotweeds form dense monocultures, outcompeting native plants, depleting native insects and other wildlife communities, and damaging infrastructure like foundations and fences. Knotweed also is incredibly challenging to control. Here I will present a successful option for controlling invasive knotweeds without the use of chemicals that is based on nine years of research. I will also present chemical-free management options for woody invasives like barberry, buckthorns, and invasive honeysuckles.
