In recent years, the condition of the Pike River banks in Stanbridge East has deteriorated, invaded by an invasive species from western Canada, the Manitoba Maple.

[French version available] The Pike River flows harmoniously through the village of Stanbridge East. In recent years, however, the condition of the banks has deteriorated, invaded by an invasive species from western Canada, the Manitoba Maple. This tree grows rapidly and colonizes the banks, threatening to fill the entire area and obscure the view from the bridge and from either side of the river, as well as preventing native species from surviving there, impoverishing the existing ecosystem.

Local Volunteers And Municipal Financing

Concerned about this issue, local councillor Marcus Flynn presented a project to revitalize the riverbanks in the section of shoreline located in the heart of the village, on the Museum property and the Farmer’s Wall Park property owned by the municipality. To restore the vitality of the banks, a plan has been devised to cut back undesirable species and remove stumps, and replant the area with a variety of native shrubs, as it is harmful to leave the banks bare.

The project was well received by the Municipality, which agreed to cover the costs—$1,200 for the purchase of plants and planting accessories. The work was carried out by local volunteers Julie Bellefroid, Éric Ciup, Andrée Lacelle and Marcus Flynn himself. Together they put in a total of 73 hours of volunteer work. Attractive, low-growing native shrubs (see list below) were selected and planted to give the area a pleasing appearance, while preserving the view from the bridge and from either shore. 

An Inspiring Project

And even if the Manitoba maple cannot be eradicated because it is so prevalent in the region, its undesirable regrowth can be discreetly removed each year without leaving the bank bare of vegetation, thanks to the newly planted bushes.

From an environmental point of view, the new vegetation will reduce runoff and erosion, help keep the banks slightly cooler through transpiration and shade, and promote biodiversity in this riparian environment important for many species of flora and fauna.

This remarkable initiative is an inspiring example of riverbank revitalization in a visible, prestigious and well-frequented location.
