Halton Hills developing new strategy to combat growing invasive species threat

By: Christian Collington, Local Journalism Initiative Reporter, TheIFP.ca

 

The Town of Halton Hills is taking proactive steps to protect its natural landscape with the development of a comprehensive Invasive Species Management Framework (ISMF).

 

Town staff said the new strategy “aims to address the rising environmental and economic risks poised by non-native plants, animals and pathogens that threaten the region’s biodiversity.”

 

Residents are encouraged to view the project page online for more details on the ISMF and can submit questions or feedback as the framework develops.

 

A 2024 study, conducted with Credit Valley Conservation and presented to council, identified 155 invasive species within Halton Hills, with plants making up 94 per cent of the findings.

 

Examples of local threats include:

 

  Plants: European Buckthorn, garlic mustard, dog-strangling vine and Phragmites.

 

  Insects and pests: Emerald ash borer and spongy moth.

 

  Aquatic species: The round goby, which has been found outcompeting native fish in Fairy Lake.

 

A presentation from town staff at an open house on April 23, explained that Emerald Ash Borer has cost Ontario municipalities millions in tree removal and treatment, while the management of phragmites during the Trafalgar Road expansion added approximately $710,000 in unbudgeted costs.

 

According to the presentation, the draft ISMF will focus on four key areas:

 

  Prevention and protection: Stopping the arrival of new species and safeguarding existing ecosystems.

 

  Collaboration and engagement: Partnering with First Nations, community groups and external agencies to gather data and share resources.

 

  Prioritization and management: Developing multi-year plans to direct limited municipal resources where they will be most effective.

 

  Monitoring and evaluation: Establishing town-wide tracking to support adaptive management over time.

 

The town is currently refining the proposed framework based on feedback from the public at the open house and will present a draft report to council in late June, followed by the final report seeking council’s approval to be presented in July.
