Mauricie National Park
La Mauricie's dense forest
cover is composed of no fewer than 30 species
of trees covering 93% of the park's area.
The park is in a transition zone at the northern
edge of Quebec's large broad-leaved forests,
which in the north end of the park gives way
to boreal forest. In the richest soil environment,
the southern sugar maple, yellow birch and beech
trees do well; pine, balsam fir and red spruce
manage best in the damp valleys and hilly slopes.
One of the oldest and largest
white spruce plantations in Canada, planted
by a pulp and paper company between 1930 and
1932 using what was then farmland, is now managed
by the park. In the Esker Bog, where the peat
is about 7 metres thick, a black spruce and
tamarack forest has taken hold. Protection and
increase of the remaining white pine has become
a conservation concern. One method of improving
its condition is to initiate a controlled burn
of the existing white pine areas, which will
re-seed if the understory of competing balsam
fir has been burned off. Balsam fir, which is
threatening to overrun the white pine, does
not successfully regenerate itself after a fire.
The 440 species of plants include some 70 species
of particular interest as rare or uncommon plants
found mostly on rocky cliffs and swampy areas.
Undergrowth in the forests is a blend of mosses
