Examining the impact of seed production on sap sugar content

Sap flow is only part of what determines the total amount of syrup made (and how much money ends up in a syrup producer’s pocket). New research suggests sugar makers may be advised to look to their trees’ canopies as well as the weather forecast if they want to predict the tapping season.

Pure maple gaining on artificial syrups

Pure maple syrup is on the rise in a declining overall market for pourable syrups. We are moving in the right direction, but still have a long way to go.

Misrepresentation of maple syrup

In the marketplace today, there are numerous instances where a product that does not contain any real maple syrup conveys in various ways, on its packaging or in its advertising and promotion materials, that it does contain real maple syrup or, even, is real maple syrup. The International Maple Syrup Institute (IMSI) and the North American Maple Syrup Council (NAMSC) believe that such behavior is misleading and deceptive to consumers, be it intentional or not, and should be curtailed, much as with any truth in advertising or labeling issue.

Measuring Sap Flow

Keeping track of the amount of sap being collected is important for maintaining high yields and minimizing losses. This article explains how to measure sap using counters mounted on releasers.

Evaluation of Sugar Maple Dieback Trends in the Upper Great Lakes Region

Crown dieback and declines in tree health of sugar maple (Acer saccharum) have been reported on various land ownerships in the western Upper Great Lakes region in recent years (MDNR 2009, 2010, 2012). In some areas, the crown dieback has affected high-value crop trees. Historically, sugar maple dieback (fig. 10.1) has been reported more frequently in the eastern part of its range and has not been described on the same scale in the Great Lakes region since the 1950s and 1960s (Bal and others 2015, Millers and others 1989). As a result, fewer studies of canopy health of sugar maple exist in the Midwest than in the Eastern United States.

Choose wisely when selecting where to tap

Knowing when, where, and how to tap is critical to making good maple syrup and keeping trees healthy.
