1998 Ice Storm Effects on the Health and Productivity of Sugar Bushes of Eastern Ontario

In 1998, fifteen managed sugar bush blocks with 7% to 72% ice-induced crown damage were established in eastern Ontario. Results suggest that severe ice storm damage to crowns resulted in reduced fall root starch levels and less sap production, and/or sap sweetness, and therefore lowered the syrup producing capacity of sugar maple.

1998 Ice Storm Effects on the Health and Productivity of Sugar Bushes of Eastern Ontario: Part 2

In 1998, fifteen managed sugar bush blocks with 7% to 72% ice-induced crown damage were established in eastern Ontario. All blocks received dolomitic lime (calcium and magnesium) and phosphorous (P) and potassium (K) treatments in June 1999. Initial crown damage, fall root starch, sap production and sweetness were all measured. Syrup production was calculated.

2010 Sugaring Season Survey

In mid-April 2010, an invitation to participate in a survey was sent to subscribers of two maple forums. The survey was designed to get some basic information about the operations of the respondents, to describe sanitation practices (changing tubing, spouts, etc.) and to get feedback from users about the Leader Check-valve adapter.

2011 Update of Maple Tubing and Taphole Sanitation Research at Cornell

During the 2011 maple sap season a variety of research trials were conducted at the Arnot Forest of Cornell University and in the woods of a number of cooperators both with vacuum and gravity systems. Research conducted over the last five years has shown that significant increases in sap yield can be obtained by keeping the tap hole from contamination by bacteria and yeast.

2012 Maple Tubing Research

In 2012 a variety of spout and tubing cleaning and replacement options were tested to determine the extent of sap yield changes. These tests were done at the Cornell Arnot Research Forest.

2013 Maple Tubing Research

In 2013 a variety of spout and tubing cleaning and replacement options were tested to determine the extent of sap yield changes that would result. Most of these tests were done at the Cornell Arnot Research Forest.

2015 3/16″ Maple Tubing Cooperator Trial

During the 2015 maple sap season the Cornell Maple Program conducted a small trial, testing sap yield from 5/16″ tubing vs. 3/16″ tubing. This trial was not conducted at the Arnot Research forest but with a small maple operation cooperator. The tubing system consisted of six lateral lines, three 5/16″ and three 3/16″ alternating between the two treatments across the hillside.

A History of Taps and Tree Size

The current ‘traditional’ tap hole number guidelines involve adding a tap for each 5 inch dbh above 10 inches dbh. ‘Conservative’ guidelines involve placing one tap in trees 12 inch dbh and a second tap in trees more than 18 inches dbh. The reasons behind the traditional guidelines are not stated in the North American Maple Syrup Producers Manual, but the conservative guidelines are suggested when there is concern for tree health. The purpose of this article is discover where these guidelines came from and to re-establish the reasons why they exist.
