Tapping guidelines for current sap collection practices
Research into whether existing tapping guidelines are appropriate to use with ‘high yield’ sap collection practices which remove a much greater amount of a tree’s sap than older systems.

Sugar Maple Sap Yields Using One or Two Tapholes Per Tree
Studies currently underway at the University of Vermont Proctor Maple Research Center (PMRC) are examining the effects of accumulating internal taphole damage on the ability to support future tapping, as well as related subjects such as the effects high vacuum sap extraction might have on tree growth, all with the goal of developing new sustainable tapping guidelines. However, along with focusing on the possible negative effects of tapping and sap extraction, it is important to examine how certain practices might lead to greater sap yields.
Results from the 2013 New England tapping survey
Results of an annual survey conducted of New England sugarmakers, capturing information on production practices and results, such as types of equipment used, sap sugar content, sanitation practices, and other data.
High Vacuum in Gravity Tubing
Gravity tubing systems are widely used in many small to mid-sized operations throughout the maple region. This article summarizes the past 3 years of my research on gravity tubing, or tubing without a vacuum pump.
Results from the 2012 New England tapping survey
Results of an annual survey conducted of New England sugarmakers, capturing information on production practices and results, such as types of equipment used, sap sugar content, sanitation practices, and other data.
How deep do you tap?
An investigation into the impact of tap hole depth on tree health.
Expanding trees: diameter growth in sugar maples
Tree growth rate can be an important indicator of how well the tree will heal from tapholes.
The state of the maple industry – 2011
A summary of the current state of maple production in New England is based on surveys returned from approximately 220 sugarmakers in April, 2011.

Root pressure in trees: a spring phenomenon
Root pressure occurs when the soil begins to warm, and when snow has melted, and icy water from snow melt has largely drained from the soil, forest soils warm quickly.
