Weed Page
My name is Kandra Forbes and I worked with Eagle Creek Watershed Group from July-March on projects such as Invasive Weed and Water Quality Awareness.
I have been worked with weed inspectors in the watershed to help identify what their problem weeds are and helped them map the spots they spray. I also worked with weed inspectors and producers to help identify new weeds that they may not be familiar with and help make sure those weeds aren’t in the Weed Act.
Underneath here you will find resources as well as some examples of weeds you may see in this area.
Feel free to check out IMap Invasives to get an idea of what weeds are a problem in certain areas of the province.
Resources recommended by Kandra and Glenn:
- Weeds of the Prairies - cost $25.00 This is a handy book to have in your truck or home it comes with excellent photos too.
