Sugar maple is a deciduous tree that can grow to a height of 50 to 130 feet. It is native to the US, and found throughout the eastern states. Sugar maple is the primary source for maple sugar and syrup. Trees are tapped for syrup in late winter/early spring throughout New England. Sugar maple is also a valuable hardwood for a variety of products from flooring to cabinets.
Red Maple is a deciduous tree that can be 50 to 60 feet tall at maturity. It is wide ranging, and native throughout the eastern half of the United States. Red maple can be used for syrup production. However, it tends to bud and flower very early in the season, which has a negative effect on the sap, making the syrup season for the red maple very short.
Due to projected increases in winter air temperatures in the northeastern USA over the next 100 years, the snowpack is expected to decrease in depth and duration, thereby increasing soil exposure to freezing air temperatures. To evaluate the potential physiological responses of sugar maple (Acer saccharum Marsh.) to a reduced snowpack, we measured root injury, foliar cation and carbohydrate concentrations, woody shoot carbohydrate levels, and terminal woody shoot lengths of trees in a snow manipulation experiment in New Hampshire, USA. Snow was removed from treatment plots for the first 6 weeks of winter for two consecutive years, resulting in lower soil temperatures to a depth of 50 cm for both winters compared to reference plots with an undisturbed snowpack.

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.
Gravity tubing systems are widely used in many small to mid-sized operations throughout the maple region. This article summarizes the past 3 years of my research on gravity tubing, or tubing without a vacuum pump.
