Tree Size Matters

In order to develop models of tree size and yield we measured the sap volume and sugar content from a wide range of tree sizes during the 2016 and 2017 seasons. This article explores the findings.

Ask Proctor

Why are my tapholes leaking and what can I do about it? (Part 1) There are often several issues involved in leaking tapholes, and sometimes the applied remedy itself turns out to be the actual problem.

Bigleaf Maple Syrup: Nontimber Forest Products For Small Woodland Owners

The sugar maple tree (Acer saccharum) is most commonly used in maple sugaring, but all maples produce sap that can be converted to maple syrup. Though not as high in sugar content as the sugar maple, the sap of bigleaf maple trees (Acer macrophyllum) grown in the Pacific Northwest produces excellent syrup.

Is Tapping Below the Lateral Line A Good Idea?

This research was conducted to determine whether tapping below the lateral line in vacuum tubing operations results in the same quantity of sap from a taphole as normal (above the lateral line) tapping, and thus whether tapping below the lateral is a reasonable management alternative which might be employed to increase the size of the tapping band in maple sap production. It will also inform us as to any tradeoffs (reductions) in yield that might result from this approach.

Sap Collection from Small-Diameter Trees

For several years, we conducted research on the collection of sap from small-diameter maple trees. This document outlines the basic concepts, techniques, and applications of this type of sap collection.

Growth Rates of Sugar Maple Trees Tapped for Maple Syrup Production Using High-Yield Sap Collection Practices

The amount of sap that can be extracted annually from trees for maple syrup production using current equipment and practices is more than double the typical yields achievable when current maple industry tapping guidelines were developed. The growth rates of trees tapped with these Òhigh-yieldÓ practices at 18 sites in Vermont were measured and evaluated to determine whether they were sufficient for the replenishment of conductive wood to remain at sustainable levels when current tapping guidelines are followed.
