Invasive species are organisms (including plant, animal, insect and pathogen species) that are not native to an ecosystem and can harm the environment. They have the ability to outcompete native species for resources and space. Invasive species often lack their natural predators or population controls, which allows them to reproduce and spread rapidly. They are often very adaptable and have the ability transform entire ecosystems.

Richmond Hill has a long history of managing invasive species throughout the city and has developed strategic approaches to manage the impacts of Emerald Ash Borer (EAB) and LDD moth (Lymantria dispar dispar), previously known as Gypsy Moth.

Presently, the City only manages invasive plants when working with Conservation Authority staff to ensure the success of woodlot restoration projects and to address regulated noxious invasive species (like giant hogweed) that pose an immediate public safety threat.

Residents looking to manage an invasive species on their own property can visit the Ontario Invasive Plant Council to discover helpful resources such as landowner guides to managing and controlling invasive plants and species specific best management practices.

What can you do to reduce the impacts of invasive species?

Plant native

When gardening, choose native plants in your landscaping. The Grow Me Instead Guide highlights common ornamental invasive plants and suggests native alternatives that are better suited to Richmond Hill’s growing conditions.

Know and report invasive species

Become familiar with common invasive species in Richmond Hill and report them when you encounter them on the trail or in the water.

Stay on the trails

When visiting Richmond Hill’s Parks, Trail and Natural Areas stay on the trails to reduce the spread or introduction of seeds in natural habitats. Make sure to clean your footwear and equipment before going from one natural area to another. This includes cleaning bikes, boats, fishing equipment, ATVs and other recreational equipment.
