SCUGOG: The Township recently unveiled an updated strategy to combat invasive species, focusing on one of Ontario’s most notorious ecological threats: Phragmites australis.
A detailed report, presented to the General Purpose and Administration Committee, outlines new best management practices, for addressing the fast-spreading wetland grass which threatens biodiversity and water quality, in areas like Lake Scugog.
Prepared by Grant Taylor, Director of Public Works and Infrastructure, the report emphasizes the need for enhanced management and funding, to control the pervasive species. "Invasive Phragmites is a significant ecological challenge, particularly in sensitive habitats like Lake Scugog," Mr. Taylor said. The plant, often found along roadsides and wetlands, forms dense stands which crowd out native plants and wildlife.
Since 2018, Scugog has been mapping and treating Phragmites hotspots, in collaboration with local organizations, such as the Ontario Federation of Anglers and Hunters. However, consistent funding has been a challenge. The program which initially received external funding, now relies on an annual $10,000 budget for invasive species management.
This year, the Township increased its commitment, by allocating $15,000 for invasive species mitigation, including $10,000 for Japanese Knotweed and $5,000 for other invasive plants. Yet challenges persist, particularly in untreated areas under the jurisdiction of the Ministry of Transportation (MTO) and the Region of Durham.
"The lack of coordinated efforts from neighbouring jurisdictions undermines our work," the report states, pointing to untreated road allowances as sources of reinfestation.
The report recommends a multi-pronged approach, combining herbicide application, mechanical cutting, and prescribed burns. While effective, these methods require precise planning and resources. Areas like Palmer Park which fall outside of the Public Works exemption for herbicide use, may necessitate collaboration with Kawartha Conservation or formal approval from the Ministry of Natural Resources.
Ward 1 Councillor, David Le Roy praised the report, and asked if staff were looking at similar strategies for tackling other invasive species which present local threats, such as buckthorn and dog strangling vine.
“Yes, we are looking at all invasive species, but primarily focused on Phragmites, and treatment along township roads,” noted Mr. Taylor. “We’re trying to avoid treatment near the water because of herbicides and our licensing to perform that work. Staff are doing their best with the budget we have.”
Regeneration of native plants is also a priority, with the report advising seeding and planting where diversity is historically low. Post-treatment monitoring will ensure long-term success.
The Township plans to engage residents, through a public communication campaign, to inform them about herbicide treatments in parks and waterfront areas. "We want to ensure transparency and educate the community about the importance of these measures for protecting our natural environment," Mr. Taylor explained.
The report underscores the critical role of sustained funding and regional cooperation in invasive species management. As the Township of Scugog continues its fight against Phragmites and other threats, its efforts aim to restore the area’s ecological health and preserve it for future generations.
