Weed alert: Canada thistle


via Sea to Sky Invasive Species

Invasive Species are problematic for Pemberton farmers. They can cause crop losses, increased maintenance costs, reduced product quality & quantity, human and animal health concerns (from mild allergies to poisonings), and lowered land values. Pemberton’s agricultural land base covers 18,600 acres of the valley, and since weeds do not respect fence lines, effective management is made much easier by neighbouring properties working together to stop the spread.

SSISC partnered with the Pemberton Farmer’s Institute and the Pemberton Seed Potato Growers Association to determine which five plants are the most problematic weeds for agriculture in the Pemberton area, and how best to manage them. Through sharing this information with the wider Pemberton community, we aim to reduce the spread of these plants and the negative impacts they have on agriculture and the environment. Explore the following factsheets to learn how to identify Pemberton’s 5 Worst Weeds, their negative impacts on local agriculture, and recommended strategies for controlling or removing them.
