The key for sap capture is that the temperature swings from cold at night to warm during the day with best results where the nighttime temperature falls below the freezing point.

As you are aware this happens both in spring and fall very commonly, but in fact it is not seasonal dependant in as much as it is weather dependent.

Commercial tree tapping tends to be more industrialized process so they aim to maximize efficiencies to get as much sap as they can in bulk so they can refine to maple syrup as part of an assembly line process of collection, and cooking the sap, so it is much more regimente das there is an "ideal" time of year to get the highest yeilds. However, you are wrong in thinking that it is the only time that you can get sap is at the peak of the season, you just get the highest yeild, something a survivalist isn't really concerned about in a survival situation when they just need enough to survive not to make a bottle of syrup.

There is of cource going to be a reasonable drip rate to make it worthwhile to tap.

Seems birches will flow above 50f where as the maple is more so temperature fluctuation.

This is good for identifying maples etc..

The flavor also changes for the worse as soon as the budds open up on the tree
