What is a Weed?

Noxious WeedsStrictly speaking, a weed is any plant growing where it isn't wanted. From chickweed in your garden to a canola plant in a wheat field, weeds are everywhere.

However, there is a piece of legislation in Alberta that recognizes certain plants as dangerously invasive and requires landowners to control or destroy these plants if they are growing on their property.

New Alberta Weed Spotter App for iPhones

Attention Weed Warriors!  The City of Edmonton has developed a free iPhone app to assist with weed identification and reporting.  It is called the Alberta Weed Spotter App and is available for download on iTunes.  This app helps you identify the weed you're looking at by plant part (such as flower colour or leaf shape) and also allows you to report infestations.  **Please note: this app is being administered by the City of Edmonton and, as such, it is very important that you input the exact address (including the city) into the Comments section of the report so that it can be forwarded to the City of Grande Prairie's Weed Inspection Department.

Dandelion Control in Grande Prairie's Greenspace

DandelionIn 2008, per Council's direction, Parks Operations ceased to apply herbicide for dandelion control on City-maintained turf areas. This dramatically reduced the amount of herbicide applied yearly to boulevards and parks.

Dandelions are an aesthetic weed; they are non-legislated in Alberta and there is no requirement for their control.

For more information on dandelion control in Grande Prairie, please contact Parks Operations at (780) 830-5018.

 

The Lowdown on Giant Hogweed

Giant hogweed (Heracleum mantegazzianum) is a member of the carrot family that is receiving a lot of media attention across the country.  From its enormous size (up to 5 meters tall) to the phytotoxic effects of its sap, everything about this plant spells hard to miss.  The City of Grande Prairie has been receiving many calls reporting the presence of giant hogweed in the area. Giant hogweed is NOT present in Alberta yet.  The most common lookalike is a native plant called cow parsnip (Heracleum maximum) that grows substantially smaller than giant hogweed.  Before you contact the City of Grande Prairie or attempt to remove the plant, please reference this factsheet (PDF, 3MB) for an in-depth comparison of the two plants to help you identify them properly.
