Jasper is a small town in a national park. Landscaping choices should reflect the natural surroundings. Residents are encouraged to choose plants and trees from the Approved Planting List (PDF).
This list contains plant species that are both native to Jasper National Park and non-native. These recommended species are unlikely to become ecological problems by cross-pollinating with native plants or spreading into the natural environment. Preferred plant species are also drought resistant and do not attract wildlife such as bears or elk.
Alien weeds spread quickly and aggressively and they cause significant ecological damage by displacing native plant communities that stabilize the soil and provide food, shelter, and habitat for park wildlife.
There are over 120 species of non-native plants in Jasper National Park, mostly occurring in areas where people have the most impact: the Jasper town site. Of these, 10 weed species are the most aggressive and do the most damage.
Herbicides will not be used to control low priority weeds in the town site, or any weeds in public green spaces, playgrounds or school yards and all sprayed areas will be appropriately signed.
99% of Parks Canada’s weed control program involves manual and mechanical weed control and herbicide use is a last resort when no viable alternative means of control exists.
What to Expect
Parks Canada will be cautiously conducting controlled spot spraying at about a dozen select locations in the Jasper town site. At the moment, most of these infestations are small (less than 10 m2) and in remote locations away from regular public use.
