Maple is a tree crop much like Cinnamon. The whole trunk produces, instead of the leaves. Like cinnamon, you right click on the trunk to get maple syrup. it yields maple syrup when harvested. Combining maple syrup with a spruce sapling creates a maple sapling (looks like a cinnamon sapling).
Maple trees can be found in taiga, and extreme hills biomes.
