The Laurentian Forest

The Biodôme's Laurentian Forest represents a deciduous forest (where the leaves actually drop in the fall). More specifically it is a sugar maple-yellow birch stand. This is the orange part on the map.

This kind of forest looks different, depending on the terrain. We chose a particular part of the La Mauricie Park, north of Trois-Rivières in Quebec, as our model. It is a hilly region in the southern part of the Laurentian plateau.

Sugar maples are the dominant species here. There are a number of companion species, the main one being yellow birch.

Good companions

In addition to yellow birch, a number of species grow alongside the sugar maples in a sugar maple-yellow birch stand. One of the most common is American beech. There are also red maple, balsam fir, tamarack, eastern hemlock and American linden.

Companion grasses

Sugar maple stands, like the sugar maple-yellow birch stand represented in the Biodôme’s Laurentian Forest, are home to many herbaceous spring plants.
