A Future Without Maple: The threat of the Asian Longhorned Beetle
The ALB poses a grave threat to maple trees, and to the maple syrup industry.
Cloudiness’ effect on refractometer measurements
Accurately measuring density is critical to the production of pure maple syrup. This article explores how impurities in syrup can affect the accuracy of tools used to measure density.
Counting Sugar Makers
Analysis of the 2012 U.S. Census of Agriculture’s report on the maple industry.
Reverse Osmosis for Maple Syrup Option 2
Cornell University’s Maple Specialist, Steve Childs reviews a second reverse osmosis system for a small-scale maple syrup producer. Reverse osmosis greatly reduces the time and energy spent in boiling maple syrup by pulling much of the water from the sap before the boiling process begins. Sap can be put through the system repeatedly and becomes more concentrated with each pass through the RO membrane. Boiling the concentrated sap at the end is always necessary however, as that greatly contributes to maple syrup’s rich flavor.
Small-scale Reverse Osmosis
Cornell University’s Maple Specialist, Steve Childs looks at a small-scale reverse osmosis unit and goes through the equipment piece by piece.
Reverse Osmosis for Maple Syrup Option 3
Cornell University’s Maple Specialist, Steve Childs, reviews one more reverse osmosis unit that is still applicable to the small-scale maple producer, despite this unit’s size.
Collect More Sap Without Vacuum Pumps
Using 3/16″ tubing can create non-mechanical vacuum that can increase sap yield.
Population dynamics of sugar maple through the southern portion of its range: implications for range migration
The range of sugar maple (Acer saccharum Marsh.) is expected to shift northward in accord with changing climate. However, a pattern of increased sugar maple abundance has been reported from sites throughout the eastern US. The goal of our study was to examine the stability of the sugar maple southern range boundary by analyzing its demography through the southern extent of its distribution. We analyzed changes in sugar maple basal area, relative frequency, relative density, relative importance values, diameter distributions, and the ratio of sapling biomass to total sugar maple biomass at three spatial positions near the southern boundary of the speciesÕ range using forest inventory data from the USDA Forest Service Forest Inventory and Analysis program over a 20 year observation period (1990Ð2010).
A New Take on Sap Collection
A new method of gathering sap from sugar maple saplings is being tested.
