Invasive species are plants, animals or other organisms not native to BC whose introduction and spread harms the province’s native species, economy and human health.

Invasives spotted locally include: Knotweed, Parrot’s Feather, Goldfish, English Ivy, European Chafer beetles, Periwinkle, Himalayan Blackberry, Yellow Flag Iris, Oriental Weatherfish and Scottish Broom.

Why should you care?

Most invasive species are unintentionally introduced by human activities into places outside their native habitat and, once they’re removed from natural predators and diseases they often reproduce, spread and choke out native species.

With few limits on their populations invasive species can easily take over sensitive ecosystems permanently upsetting the balance of plant, insect, bird and other animal life. Local governments, including Pitt Meadows, spend thousands of dollars each year to try to manage invasive species in our communities.

How can you help?

Report It

If you see a plant that looks out of place or a creature you don’t recognize and have concerns about, we encourage you to report it. Invasive species tend to pop up in areas that we frequent – like dog walking trails and local parks, or along roadsides and in ditches. Thank you for taking action by reporting invasive species you see!

Invasive Species in Pitt Meadows
Parrot's Feather

Parrot's Feather (Myriophyllum aquaticum) is an aquatic plant, often sold for use in aquariums and home ponds. They colonize water bodies and drainage systems choking ditches preventing natural flow. They reproduce by fragmentation, so a small fragment is all that is needed to produce huge mats. There is a huge cost to the City for managing this invasive plant. Please do not place unwanted aquarium plants in ditches, or any watercourse.

European Chafer Beetle

The European Chafer Beetle (Rhizotrogus majalis) is an invasive insect pest that is new to the Metro Vancouver region.  Its larvae feed on the roots of grasses, causing serious damage to lawns.

Chafer beetle infestation is often most visible when raccoons, birds and other wildlife, eager to eat the grubs, begin digging up grasses and damaging turf.

Knotweeds

Knotweeds originated from Asia and were brought to British Columbia as an ornamental plant.  They’re known as one of the 100 worst invasive species internationally and top 10 for control in our province. 

Knotweeds have significant economic, ecological, social impacts. Their vigorous growth can penetrate through concrete and asphalt. Disposal of knotweed requires careful consideration. Please refer the attached Fact Sheet for more detailed information. Residents are NOT to use their residential organic/green waste carts for disposal of Knotweed. BC Earth Exchange, on Bonson Road & Fraser Way, offers pick up of Knotweed removed from private property.

Goldfish

Goldfish (Carassius auratus) are native to eastern Asia, including parts of China, Hong Kong, Japan and the Republic of Korea – not Pitt Meadows!

Goldfish are being intentionally released into B.C. waterbodies by pet owners and escaping from outdoor ponds and aquariums. This species is an effective invader for its abilities to rapidly reproduce, withstand temperature and oxygen level changes, and spread quickly to surrounding water bodies. The Ministry of Forests, Lands and Natural Resource Operations says releasing aquarium fish into the wild remains illegal, and is reminding the public to return any unwanted fish to pet stores rather than freeing them.

For more information:

Oriental Weatherfish

Oriental Weatherfish have spread through human assisted introductions in the aquaculture and aquarium trades and as live bait. Oriental Weatherfish reduce the amount and diversity of aquatic insects, and compete with native fish species for food.

The Ministry of Forests, Lands and Natural Resource Operations says releasing aquarium fish into the wild remains illegal, and is reminding the public to return any unwanted fish to pet stores rather than freeing them.

Mosquito Control

The City participates in the Metro Vancouver Regional Nuisance Mosquito Control Program. Carried out by professional mosquito contractor Morrow BioScience Ltd., the program involves routine monitoring and sampling as well as the use of larvicides.

To report mosquito-related concerns, call 604.432.6228.

Mosquito FAQ

Frequently Asked Questions
How do I dispose of invasive species?

Contact the City Operations department at 604.465.2434 for any disposal advice. All removed invasive plant material should be disposed of properly. If you are a resident looking to dispose of invasive plants or soil containing invasive species, be aware that some facilities may not accept the material due to risk of further spread. DO NOT put invasive plants in a backyard composter as the temperature will not get hot enough to destroy these plants and their seeds. BC Earth Exchange, on Bonson Road & Fraser Way, offers pick up of Knotweed removed from private property.

What should I do if I see an invasive plant on public property?

If you see a plant that looks out of place or a creature you don’t recognize and have concerns about, we encourage you to report it. Invasive species tend to pop up in areas that we frequent – like dog walking trails and local parks, or along roadsides and in ditches. Thank you for taking action by reporting invasive species you see!

To identify which type of invasive plant species you’ve encountered, please visit the ISC Website.  

We continue to work with other levels of government and local environmental groups to ensure that we develop a detailed inventory of invasive plants found in our parks, water courses and protected lands.

What do I do if I find invasive plants on my private property?

The B.C. Weed Control Act imposes a duty on all land occupiers to control designated noxious plants.  The purpose for the Act is to protect our natural resources and industry from the negative impacts of foreign weeds.

We recommend that citizens contact a qualified business whose applicators have the ‘Pesticide User License' certification.  While we know that some may be tempted to take the ‘DIY' approach, the concern is that the foliar spraying of invasive plants in the wrong concentrations or under the wrong conditions may end up doing collateral damage to other plants in your garden, or your neighbour's garden.
