made a ruling on April 28, 2006, allowing
Kruger Inc. to resume its logging activities.
The island is also the object of an environmental/ecological campaign lobbying the government of Québec to create a protected area spanning the entire island. The group, SOS Levasseur,
arose in 2003 partly from the interest that mainstream environmental groups in Québec demonstrated during environmental consultations. All groups recommended that René-Levasseur Island be protected in its entirety. The Island has been proposed as a Canadian National Park, an ecological reserve, a biodiversity reserve and an exceptional geological site. There seems to be an exceptional concentration of old-growth boreal forest stands on the island.
SOS Levasseur has been conducting research expeditions on the island since January 2005, whose aim is to identify
old-growth forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Natio ...

The MRNFQ has yet to recognize the seven sites proposed by SOS Levasseur.
