Sugar bush refers to a forest stand which is utilized for maple syrup. The tree canopy is dominated by sugar maple or black maple. Other tree species, if present, form only a small fraction of the total tree cover. In the Canadian provinces of New Brunswick, Ontario, Quebec and Nova Scotia, and in some New England states, many sugar bushes have a sugar shack where maple syrup can be bought or sampled.

The maples are tapped for their maple sap in early spring, whenever the weather has warmed so that day-time temperatures are above freezing — 0 °C (32 °F) — while night-time temperatures remain below freezing. The tapping period ends when the supply of maple sap ceases, as when night-time temperatures begin to be above freezing, or when the tree produces metabolites to facilitate tree bud development (which will give syrup an off flavor)--whichever comes first. After the tapping period, some maple sugar bushes experience a profusion of spring wildflowers which take advantage of unobstructed sunlight before the maple leaves emerge. In summer, a healthy maple sugar bush is luxuriant and shady. Autumn leaves are colorful, especially on the sugar maples.
