An observation guide for your stay: mixed forests, wild shorelines,
waterside blooms and emblematic canopy trees — what to spot, when,
and how to enjoy the places without harming them.
Laurentian forests — domain of the yellow birch–maple
forest: sugar & red maple, birches (yellow & white), beech,
trembling aspen, eastern hemlock, balsam fir, spruces and white pine
[4][6].
What to notice at a glance?
Even on a short stroll you’ll spot the mosaic of broadleaf
and conifer: pale birch trunks, broad maple leaves, and
the cool shade of hemlocks. In autumn the maples set the canopy
ablaze; in spring, shores brighten with irises and fresh shoots.
Sugar maple: 5-lobed leaf, source of the famous syrup.
Yellow birch: bronze-gold bark in fine ribbons.
Hemlock: small cones; two pale lines on needle undersides.
“Kept-wild” shoreline at the Refuge — this vegetated belt
between forest and water holds moisture, stabilizes banks,
filters sediments and keeps water cooler for fish
[1][3].
How to recognize & respect it
Look for diversity: grasses, sedges, willows, alders, dogwoods,
young birches… It’s normal that it’s a bit “bushy” — that’s
what protects the river.
Stay on existing access points; don’t make new paths.
Avoid trampling wet banks and emergent plants.
Take photos, use binoculars… and leave everything in place.
Streamside shrubs — red-osier dogwood
(red twigs), willows and alders knit the banks
together and shelter many birds
[3].
Blooms & emergents — blue flag iris,
cattails, arrowheads, pickerelweed:
great photo subjects and refuges for frogs and dragonflies
[3].
Quick waterside observation ideas
Spot the red twigs of dogwood in late winter.
In June–July, look for violet irises and
dragonflies perched on stems.
After rain, listen for the “plop” of amphibians in the reeds.
Conifers to spot on the trail
White pine: long needles in bundles of 5,
tall slim crown; hemlock: soft needles and tiny cones
hanging from horizontal twigs.
Cool ravines: often hemlocks.
Rocky knolls & ridges: solitary white pines.

Dominant broadleaf trees
Sugar maple (5 lobes, syrup), red maple
(3 lobes, reddish sap), yellow birch (yellow-bronze
bark, ribbons): the three most common species around La Macaza
[4][6].
In autumn the maples light up the canopy; in spring, shores show irises and fresh shoots.
Paper birch is rarer here than in the boreal forest, but easy to spot by its white bark.
Blooms, berries & pollinators
Edges and clearings offer a steady bloom (asters, goldenrods,
daisies) and wild berries (raspberries, lowbush blueberries).
Watch for butterflies too, and from June–August, the common milkweed,
host plant of the monarch
[8].
Foraging: only where allowed, in very small amounts — and leave plenty for wildlife.
Never eat a plant unless you are absolutely certain of the ID.
Special habitats & rare plants
Mont-Tremblant National Park holds several rare plants
tied to micro-habitats (bogs, sandy shores, marshes).
Please stay on trails and admire from a distance
[7].
Invasive exotics: how to avoid spreading them
Japanese knotweed and common reed
quickly colonize banks and ditches. As a visitor, help limit spread:
clean shoes & gear, stay on paths, and don’t pull plants (it fragments them)
[10][11].
