Parks and Recreation: Weeding out invasive species
By Keziah Lesko-Gosselin on May 6, 2019.
From agriculture to zooplankton, environmental policy in Alberta covers a vast array of topics. To practice due diligence, it is important to remain aware of which legislation applies to you. Whether it comes down to weeds growing through cracks in a driveway, or invading a crop field, weed control is a legislative issue which impacts many people. Weeds are found almost everywhere, and are governed by various laws, including the Province’s Weed Control Act and Regulation, and the City of Medicine Hat Bylaw No. 1982. The provincial government’s website is also a great resource for quick and simple information on weed legislation. The two types of restricted weeds in Alberta, noxious (example: downy brome) and prohibited noxious (example: Russian knapweed), must be controlled, however prohibited noxious weeds must be destroyed if found on one’s property. Provincial legislation authorizes authorities to issue penalties regarding non-compliance. Depending on the offence, fines of up to $5,000 may be issued under the Weed Control Act. While the penalties seem daunting, a simple component of weed control is to understand how the legislation applies to you. Many nuisance plants are not restricted, as listed plants need to pose significant economic, agricultural, health or environmental threats. For example, many common nuisance plants like dandelion are not regulated, but would never be found in a flower shop. However, baby’s breath is noxious, but still sold in many garden centres. Knowing which plants are, and are not, restricted can help you concentrate weed control efforts where they matter most. City of Medicine Hat Parks and Recreation is committed to effective invasive species control in public parks, however weed control on private lands is just as important to stopping the spread of invasive species. When growing plants at home, opt for native species that grow well in the Prairie region, like golden currant or prairie coneflower. Many non-native plants like Russian olive are not restricted, but may become invasive if given the chance to grow and spread. Native plants also require less irrigation and fertilizer, making your garden more affordable and environmentally-friendly long term. Local garden and nature centres, and the Alberta Native Plant Council are great resources to consult when choosing plants for your yard. Weeds do not respect property lines, and will invade given any possible chance. Their control is only effective if everyone participates – when it comes to invasive species, your action really does make a difference. Native plants need you!
