Canadian municipalities are making efforts to prevent the sale of invasive plants in local garden centers, while advocates are urging the Canadian government to establish a national strategy for regulating the horticultural industry. In response to the threat invasive plants pose to biodiversity nationwide, cities are stepping in to address gaps in the current regulatory framework, which varies by location. Canada has committed to reducing the introduction and establishment of known invasive species by at least 50% by 2030.
The Canadian Coalition for Invasive Plant Regulation (CCIPR) is calling on the federal government to create a regulatory body for the horticultural sector and develop a national database that identifies invasive plants and their associated risks in different regions. CCIPR co-founder Cathy Kavassalis emphasized the importance of informing the public about potential harm posed by invasive plants, suggesting that similar to other products, plants should also come with warnings or information labels.
While the Canadian Food Inspection Agency (CFIA) oversees some invasive plants under the Plant Protection Act, individual provinces and territories have their own legislation for managing invasive species. The CFIA noted that their approach is based on species-specific risks rather than a blanket ban on all invasive plants across the country. They highlighted that regulating invasive plants is a collaborative effort involving federal and provincial authorities, municipalities, industry stakeholders, and invasive plant organizations.
Recent actions by Canadian cities underscore the growing concern over invasive plants. Nanaimo and Surrey have moved to restrict the sale of plants listed by the Invasive Species Council of B.C., while London’s environmental committee recommended that retailers provide information about invasive plants and animals to customers at the point of sale. These localized initiatives are seen as temporary solutions, prompting calls for a more cohesive national strategy to address the issue.
Advocates stress the need for federal intervention to meet the 2030 target set by the government, with a focus on regulating the horticultural trade. Studies have shown that ornamental non-native plants sold in nurseries can be a primary pathway for introducing invasive species. Establishing a national database could enhance information sharing among provinces, territories, retailers, and gardeners regarding the risks associated with specific plants.
Experts like Jim Hole, a former greenhouse owner, believe that most garden centers would support measures to curb the spread of invasive plants. He emphasized the importance of research, regulation, and public education in controlling unwanted species. Native plant advocate Lorraine Johnson highlighted the role of nurseries in promoting biodiversity loss by selling non-native plants that may not support local ecosystems.
In conclusion, the push for federal regulations in the horticultural industry reflects a broader effort to combat the spread of invasive plants and safeguard Canada’s biodiversity. The collaboration between different levels of government, industry stakeholders, and the public is crucial in addressing this pressing environmental challenge.
