Protection of ecosystems

Guide and accompany the citizens of Haute-Yamaska, including the owners of natural environments, in their common desire to protect and restore ecosystems and biodiversity.

A diversified fauna and flora

The Haute-Yamaska ​​territory is home to several animal species such as the snapping turtle, grass snake, monarch butterfly, least bittern, etc. It is also home to several plant species such as Labrador tea, pitcher plant, fragrant water lily, cardinal lobelia, etc.


The preservation of the wealth of the territory for future generations. SETHY works with several school boards to create projects related to the environment. Several programs exist to offer learning and discovery opportunities to the youngest.

A wealth to (re)discover

Keep a close eye on the biological diversity of your property: you can make amazing discoveries! Your territory may be home to rare species of flora and fauna, each as important as the next. Pay particular attention to wetlands. Not very favorable for agriculture or walking, these environments are very rich!

Green belt project

The Foundation for the Safeguarding of the Ecosystems of the Haute-Yamaska ​​Territory is currently pursuing, and has been for several years, a project to conserve natural environments in the RCM of La Haute-Yamaska. Natural environments occupy an essential place in our daily lives and play a positive role in our quality of life, our health, our leisure activities and our economy (maple sugaring, tourism, hunting, etc.). However, action is needed now to preserve these ecosystems.


In 2020, the belt project
green consists of three elements

- Maintain an interrelated network of natural environments.

- Connect Parc national de la Yamaska ​​with the forests of Mount Shefford, the wetlands of the Saint-Joachim-de Shefford peat bog and other important natural heritage sites in our region.

- Improve the quality of watercourses in the basin
slope of the Choinière reservoir.

Control of invasive alien plants

Since 2013, in collaboration with the Conseil québécois des
invasive alien species, the SÉTHY Foundation has developed expertise in the control of several invasive alien plants, including Japanese knotweed, giant hogweed, reed.

Our expertise includes the following services

-Development and implementation of control, eradication, monitoring and experimentation programs

-Ecological inventory and characterization

-Citizen and municipal awareness and education (information sessions, conferences and practical workshops)

-Preparation of popularization and awareness-raising tools (eg interpretation panels, leaflets).

Connectivity project and plantation project

Haute-Yamaska ​​has an astonishing richness in terms of fauna and flora diversity. For example, more than twenty animal species in a precarious situation have been identified near you.
It is imperative to consolidate the connectivity between natural environments in order to create favorable conditions for the movement of sensitive wildlife species and the survival of vulnerable plant species. As a result, the SÉTHY Foundation meets with owners of natural environments to explain to them the ecological wealth of their land, but also the importance of preserving their natural attractions.

The plantation project improves connectivity between natural environments. The SÉTHY Foundation targets and organizes planting of trees and shrubs by pairing school groups with natural environments in loss of biodiversity. This creates a ripple effect to organize other plantations in the communities of Haute-Yamaska. In addition, the direct positive impact on climate change and
connectivity is undeniable.
