The bur oak (Quercus macrocarpa), in addition to producing the largest acorns, is the hardiest of the oak family in Quebec. Without bitterness, its acorns have economic potential as a food source, rich in protein and oil.

This noble tree, with its imposing stature, also provides high-quality, rot-resistant wood, and its bark is fire-resistant. Preferring rich, deep soils, it can live for 200 to 400 years but is adaptable to various environments, as long as there is good drainage. While it thrives in fresh, moist soils, it is also drought-resistant due to its deeply rooted system. In riparian zones, it can withstand temporary flooding. The bur oak stands out for its resistance to diseases and insects as well.
