The Emerald Ash Borer: A Small but Formidable Foe

Visitors of the Gault Nature Reserve sometimes wonder why so many dead or dying trees are found in the forest and why the forest floor is full of debris. This is because the forest is left unmanaged—and this is on purpose! Under normal conditions, trees in a forest do not require human intervention. After all, they did just fine for many millennia. Mont Saint-Hilaire has one of the last remnants of old-growth forest in the region. This old-growth character contributes to the exceptional value of the Reserve for teaching and research.

 

Unfortunately, the forest is not immune to the unintentional consequences of human activity. One such formidable foe has recently arrived: the emerald ash borer (Agrilus planipennis). This invasive species of insect threatens forests by attacking ash trees. An affected tree can take up to 10 years to die from an infestation. These trees, however, are more prone to falling in high wind conditions endangering visitors hiking the Reserve’s trails. Our team works hard to examine ash trees located along the trails throughout the year. When they find signs of an emerald ash borer infestation, they cut down the hazardous tree.

Cute as a Button

What a sweet surprise to spot a tufted titmouse sitting at your bird feeder or perched high up in a tree! This small, cheerful‑looking passerine can be identified by its impressive grey crest, grey upper body, big black eyes and dark forehead marking. Increasingly frequent sightings of the species in southwestern Quebec indicate that it is expanding its range in the northeast, likely due to global warming. Nesting in a woodpecker hole or natural cavity, the tufted titmouse feasts on a variety of insects, as well as seeds and acorns.

Skiing in a Winter Wonderland

Thanks to heavy January snowfalls, the Reserve has been able to open its full network of groomed cross-country ski trails. Skiers can enjoy exploring 8 km of narrow, winding and mountainous classic trails.

 

Ski season is well underway, but conditions may change due to thawing. Our website has up‑to‑date information on ski trail conditions, right on the home page—when in doubt, check before leaving home.

 

Yellow Birch

The yellow birch (Betula alleghaniensis) is Quebec’s official tree. It is commonly confused with the white birch (also known as paper birch), but you can tell them apart with one simple test: pick up a twig and scratch it. If it smells minty, you’re looking at a yellow birch.

 

The Abenaki would use yellow birch as an energy booster during long winter treks between camps, much like modern hikers reach for energy bars, explains Michel Durand Nolett in his video.

Blast from the Past

Changes in 1958

McGill University Takes Over Management of the Gault Estate

In 1958, McGill University, as the new owner of the mountain, began using the Gault Estate (as the Reserve was known at the time) for research and teaching. The university appointed its very first director, Professor Patrick D. Baird from the Department of Geography, to manage the site. It was under his supervision that Mont Saint‑Hilaire’s modern era of biology, geology, ecology and geography research work began. In the 1960s, McGill set up the first weather station in the field, to serve as a base camp for climate research. Today, no trace of the station remains.

 

Although the Gault Estate was now dedicated to research and teaching, it remained open to the public to provide an exceptional outdoor environment for recreational activities.
