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.

Sugar Profiles of Maple Syrup Grades

Although many analyses of the chemical composition of maple syrup have been conducted, relatively little information exists on the differences in composition of the individual syrup grades. As a first step in acquiring this information we performed a study to determine the characteristic sugar composition of each maple syrup grade.

Sugarbush Management and Chainsaw Safety

Maple production requires sugarmakers possess a diverse set of skills in order to tend the forest resource and maintain a productive sap collection system. Maintaining a healthy, diverse sugarbush that maximizes its growth potential requires periodic vegetation management activity. Also known as thinning, vegetation management is the process of reducing competition for light, water and nutrients of crop trees. Felling trees is the key activity in vegetation management and may be done by logging professionals in support of formal forest management plan objectives or by the sugarmaker or landowner on an as needed basis and including response to extreme weather events.

Sugarbush Management Notebook

A sugarbush is a special type of woodland. Woodlands include a complex mixture of natural processes and attributes such as soil type, elevation, tree species, types of wildlife, history of use, tree age and more. Foresters can help maple producers gain an in-depth understanding of these factors to achieve a healthy and productivity sugarbush, but there are several steps a maple producer can take on their own.
