The Lac Saint-Pierre archipelago, located in the Sorel-Tracy area, is an environmental treasure with an exceptionally rich marsh that makes up 20% of the remaining wetlands bordering the St. Lawrence River. Together with other area associations, QIT-Fer et Titane ensures that the environment in this area is preserved and promoted.

Since 1995, the Centre d’interprétation du patrimoine de Sorel has actively promoted this unique ecosystem by means of exhibits and educational activities. QIT-Fer et Titane is a founding member of this heritage centre and its primary partner.

In 1998, QIT became an active participant in a campaign to have the wetlands of Lac Saint-Pierre recognized as a Ramsar site.

In 1999, QIT joined forces with the "Société d’aménagement de la baie Lavallière" (SABL) to set up 400 bird houses in the green belt of the Bas-Richelieu so that the Eastern screech owl and the saw-whet owl, two bird species that were abandoning the St. Lawrence Valley, could nest. Today, these species are returning to the region.

On June 8, 2001, Lac Saint-Pierre was officially recognized by UNESCO as a biosphere reserve. The ceremony was the crowning glory of nearly ten years of combined efforts by numerous individuals and organizations in the region, by the Canadian and Quebec governments, and by QIT-Fer et Titane. A strong supporter of this project from the very beginning, QIT reconfirmed its commitment to protecting and advancing this natural heritage site by pledging to be its main industrial partner for the next four years. The reserve is managed by the Coopérative de solidarité de la Réserve de biosphère du Lac Saint-Pierre, which can be reached at (450) 746-9441 or 1-800-474-9441.

On June 23, 2001, QIT entered a four-year partnership with SABL to found the interpretation centre La Maison du marais, Fer et Titane. Nature-lovers will be able to enjoy the beauty of largest marsh on the St. Lawrence River, thanks to the centre’s nature trails and canoe and pontoon excursions.
