And two more graphs if anyone is interested. The graphs show the relationship (or lack of relationship) between tree diameter, spile orientation, and sap production of the trees in my bush during the 2015 season. Note that I use the term estimated sap in the graph as I have estimated values for the odd occasion when wind blew a bucket off a spile or precipitation discoloured the sap (I directly measured 3034L of sap which was actually collected and boiled and estimated an additional 53L of sap for the purposes of these 2 graphs). Also please note that for the 2015 season, I only installed one spile per tree. Enjoy!
