The Government of Alberta regulates the spread of invasive species through the:
These Acts allow for enforcement to ensure invasive species are properly destroyed and/or controlled. Both the City and residents have a role in protecting the community from invasive species.
The City manages weeds and pests in parks and green spaces through the Integrated Pest management Plan (IPM). The IPM is a decision-making model that factors environmental considerations when outlining the steps to prevent and manage pest problems. While some weeds are managed through mechanical control methods like mowing, some spots may use chemical methods like herbicides.
When a herbicide is applied, it is approved by the Canadian Pest Management Regulatory Agency (PMRA) of Health Canada. Signage is also posted at the site during and following its application. Please stay off these areas and keep pets and children away. If you spot an invasive weed or pest, please report it via SeeClickFix.
Residents have a role in helping to eliminate regulated noxious weeds and invasive pests at home to stop the spread from harming Leduc’s biodiversity. Property owners of residential, commercial, under construction and/or vacant lots are subject to the Provincial Acts.
Under the Alberta Weed Control Act, Enforcement Services can conduct routine inspections of private properties to identify problematic vegetation and work with property owners to ensure timely removal or control.

Black knot (Apiosporina morbosa) is a fungal disease pest that commonly affect cherry trees (Prunus spp.) They start as greenish brown swellings on the stems and after two years become black swellings, which can lead to growth issues that can eventually kill the tree. When spores are released, they can quickly increase infections in nearby trees.
To remove black knot, prune out the infected branches (15 to 20 centimeters below the knot) between late fall and early spring when the plant is dormant. Sterilize your cutting tools between each cut using warm soapy water or a bleach solution (one part bleach and three parts water) to prevent further spread of the disease.
Diseased wood must be bagged and placed in your black bin.
