Maple is not the only tree that you can get useful sap from for example here is a quote:
“Although sugar maples are the tree of choice for commercial sugaring due to their high ratio of sugar to water in their sap, many other types of trees can be tapped to make syrup, including silver and red maples , hickory , birch , box elder , and walnuts”
Pine trees can also be tapped for their pine resin which could be useful for crafting.
What do you guys think or care to expand upon? Would it make for interesting additions or is just unnecessary redundancies?
