Did you know?
– Each spring, frosty nights and warmer days trigger the sap flow within the tree. Tap a hole in the tree, collect the watery sap, and boil it down until two-thirds of the water has evaporated – you have a maple syrup!
– Native people drank maple sap fresh from the tree as a cold refreshing beverage.
– Rich in protein and fat, and low in carbohydrates, maple seeds are prime pickings for cardinals and grosbeaks. Chipmunks and squirrels harvest the seed crop for in-tree dining and take-home for future consumption.
