Tapping Zone Model – Tubing

This model estimates the proportion of clear, conductive wood in the tapping zone of an individual tree each year (for 100 years) based on the values input for tree diameter, tapping depth, spout size, number of taps, and dropline length. This is equivalent to the chances of tapping into conductive wood in this tree each year Ð if 80% of the wood in the tapping zone is conductive, you have an 80% chance of hitting conductive wood when you tap that tree. The model can be used to estimate whether various tapping practices are likely to be sustainable. A more complete description of the model and guidelines for its use can be found in the companion technical report “A Model of the Tapping Zone”, which is available on the UVM-PMRC website (http://www.uvm.edu/~pmrc).

Making Cornell Maple Syrup

In the Spring, maple trees begin to move sap up from their roots. At the Arnot forest, this sap is collected and then boiled down to produce maple syrup. In this video, Prof. Brian Chabot, tells us about the process and we see how maple syrup is made.

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.

Ask Proctor

Should I use 3/16″ or 5/16″ tubing? One of the first questions maple producers face when deciding to tube (or retube) a sugarbush is whether to use 3/16″ or 5/16″ tubing. This article explains some of the general rules that can be helpful in narrowing down the pros and cons of each approach.

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.
