London Invasive Plant Management Strategy

Invasive plants are a threat to London ecosystems, economy, and social and recreational environments. As many invasive plant species lack natural enemies, they can out-compete colonies of important native vegetation, negatively altering existing ecosystem function and recreational enjoyment.  To combat this issue, the City initiated the control of invasive species in 2006 and the London Invasive Plant Management Strategy in 2017.  London is the first city in Ontario to adopt a municipal invasive plant management strategy.

The City of London is an identified leader among other municipalities and other levels of government in demonstrating a proactive approach to the management of invasive species in parks, woodlands and Environmentally Significant Areas (ESA) since 2006.
