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.

Understanding the relationship between tree size and yield

There are several important factors that affect the yield of sap from trees during the production season. One relationship that it sometimes overlooked is the one between tree size and yield.

Results from the 2014 New England tapping survey

Results of an annual survey conducted of New England sugarmakers, capturing information on production practices and results, such as types of equipment used, sap sugar content, sanitation practices, and other data.

The state of the maple industry – 2011

A summary of the current state of maple production in New England is based on surveys returned from approximately 220 sugarmakers in April, 2011.

Why do some maple trees produce more sap?

Many researchers, in addition to many sugarmakers, have observed that there is a great range in the amount of sap produced from individual trees in a forest. Understanding, and perhaps predicting the different performances of the trees in a sugarbush is an aspect of maple physiology that remains fascinating.
