Sugar maple (Acer saccharum) is a keystone species in the forests of the northeastern and midwestern United States and eastern Canada. Its sustained health is an important issue in both managed and unmanaged forests. While sugar maple generally is healthy throughout its range, decline disease of sugar maple has occurred sporadically during the pastfour decades; thus, it is important to understand the abiotic and biotic factors contributing to sugar maple health.

Sap ladders have been developed by maple producers in response to the challenge of transferring sap over gradients in sugar bushes. The main objectives of the present study are to learn more about sap ladders so that recommendations can be made regarding their comparative effectiveness.
Ice storms and resulting injury to tree crowns occur frequently En North America, Reaction of land managers to injury caused by the regional ice storm of January 1998 had the potential to accelerate the harvesting of northern hardwoods due to concern about the future loss of wood production by injured trees. To assess the effect of this storm on radial stem growth, increment cores were collected from northern hardwood trees categorized by crown injury classes. For a total of 347 surviving canopy dominant and subdominant trees, a radial growth index was calculated (mean annual increment for 1999-2000 divided by the mean annual increment for 1995-1997).
Invert sugar content of syrup determines how well the syrup will crystalize when making value-added products. This article explains how to conduct that test.
Maple producers contemplating the use of high pressure steam should carefully plant their steam system with the assistance of qualified persons. Proper boiler selection to meet the system requirements is an important step in the success of any steam system.
