Weed Wise in Medicine Hat
Medicine Hat is host to a number of invasive plant species listed under Alberta’s Weed Control Act. Many of these plants are aggressively spreading and choking out our natural vegetation. Under the Act, all landowners are responsible for destroying those plants categorized as Prohibited Noxious. Plants listed as Noxious must be controlled by limiting their growth and preventing the dispersal of seed. A shared effort is required to ensure our community remains a vibrant and beautiful place to live.

Please take the time to learn more about the invasive plants found in Medicine Hat and how you can help control them. For more information contact the Parks and Recreation department at 403.529.8333.

Why should we care?
The reality is that invasive plants impact us all. They have the ability to cause significant environmental and ecological damage. They have special characteristics that allow them to out-compete native plants, thereby altering our city ecosystems and landscapes. They also cost a lot in time, money and effort to control.
