History
In 1978, private clubs for hunting and fishing were abolished and replaced by zones d'exploitation contrôlée (harvested controlled zones) with the objective to democratise their activities. Consequently, the territory of the reserve was transferred to zec du Chapeau-de-Paille.
The Irenée-Marie ecological reserve was created on October 31, 1985 by a decree of the Quebec Government. It was the 13th ecological reserve to be created in Quebec.[4]
