The Domaine de Maizerets is threatened by an invasive plant species

Le Domaine de Maizerets est menacé par une plante envahissante

The City of Québec and the regional environmental Council (CRE) is launching a call for assistance to the public in order to preserve the biodiversity of the Domaine de Maizerets, which is threatened by Japanese knotweed, an invasive plant species “out of control”.

Difficult to eradicate, this plant could spread throughout the site and take over other plant species in a few years if nothing is done, warns you.

Chores grubbing will be held throughout the summer, Tuesdays and Thursdays, from 10am to 15h. Nature lovers who want to give a boost to volunteer can show up without an appointment, during these hours, the Domain Maizerets.

They will provide on-site shovels and the necessary equipment to pull off this plant, also known as the “bamboo japanese” because of its hollow stems and knobbly similar to those of the bamboo. The manual extraction is preferred. It is out of the question to use the herbicide Roundup for this kind of operation, a-t-on insisted at a press conference.

About 3 hectares, on the 27 the natural environment near the centre of the city, are affected by Japanese knotweed, a plant that figure in the top 100 worst invasive species of the planet according to the international Union for the conservation of nature, recalled the councillor Suzanne Verreault. The City of Quebec is allied to the CRE for the operation “I pull”, which will take place throughout the summer.

In Quebec since a long time

“The plant is in the process of invading the middle. It is a beautiful plant, but it takes up all the space. It’s been 10 years, it exists here [in the Domaine de Maizerets]. Maybe we waited a little too late before treating knotweed”, concedes David Just, of the CRE, without wanting to throw the stone to that either. The public park, popular with birders, belongs to the national capital Commission, but it is managed by the City of Québec.

“Four employees to do the control, probably as the plant moves more quickly as we” shows there to understand at what point this perennial fast growth is invasive. “It is for that reason that we request the assistance of the public. It is a hot spot, here, but it’s everywhere in Quebec, said Mr. Come, in a meeting with the media on the site.

Control operations were also carried out on the coteau Sainte-Geneviève. Other sites, such as the Victoria park, however, have been spared until now.
