The sugar maple is America's most popular tree and is known for its syrup, or syrop as the French explorer called it. In late winter, the trees are bored so that the sap runs out. A medium-strength tree yields about 50 litres of sap per year, from which 1 kg of sugar is extracted by thickening. Sugar production is no longer as important today as it was at the turn of the century, but it is still economically important.

Sugar maple is the most important maple species in North America and grows there in the eastern part, from Newfoundland to the Gulf of Mexico, but is absent in Florida.
Trunk and bark
The sugar maple tree reaches a height of 30 to 40 m and a diameter of up to approx. 1 m. It only occurs in association with other hardwoods. The bark of the sugar maple is light-coloured and thin.
