Join the fight against invasive plant species – attend an Invasive Weed Pull event to learn how to identify and remove invasive plant species from Lethbridge's natural areas! 

Invasive Weed Pull events help to protect the natural biodiversity of our region. We encourage our community to participate so we can effectively deploy an 'Early Detection, Rapid Response' for prohibited noxious weeds in our river valley. Specifically, Invasive Weed Pull events target spotted knapweed and diffuse knapweed.

No pre-registration necessary (but it is encouraged), simply meet at the designated location on the corresponding date/time. We provide gloves, bags, and orientation so you know what to look for!

Weedy Wednesdays in 2024

Do your part to protect our local biodiversity on the third Wednesday of every month from May to August! Drop-in at the locations below anytime between 6-8pm to get an orientation and supplies, then help us minimize the impacts of prohibited noxious weeds.
