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. Bioclimatic domains of the Southern Québec Ecosystems of North America 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 shrubs The main shrubs are striped maple, mountain maple, mooseberry, American fly-honeysuckle, red-berried elder, ground hemlock and alternate-leaved dogwood. 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.
