The Forests of Southern New England, 2012
This report summarizes the U.S. Forest Service, Forest Inventory and Analysis (FIA) forest inventory data, collected from 2008 to 2012, for Southern New England, defined as Connecticut, Massachusetts, and Rhode Island. In addition to providing regional and state-level summaries, the reports highlights three focus plots, one average or prototypical plot from each State, as a means to better tell the story of the forests of the region. Forests cover an estimated 5,128,000 acres or 59 percent of Southern New EnglandÑ1,736,000 acres in Connecticut (56 percent of the State), 3,028,000 acres in Massachusetts (61 percent), and 364,000 acres in Rhode Island (55 percent). There was no substantial change in the area of forest land between the current, 2012, and the previous, 2007, FIA inventories.
New York Forests 2012
This report summarizes the second annual inventory of New YorkÕs forests, conducted in 2008-2012. New YorkÕs forests cover 19.0 million acres; 15.9 million acres are classified as timberland and 3.1 million acres as reserved and other forest land. Forest land is dominated by the maple/beech/birch forest-type group that occupies more than half of the forest land. The sound wood volume on timberland has been rising and is currently 37.4 billion cubic feet, enough to produce saw logs equivalent to 93.7 billion board feet.
Forests of Vermont and New Hampshire 2012
The first full remeasurement of the annual inventory of the forests of Vermont and New Hampshire was completed in 2012 and covers nearly 9.5 million acres of forest land, with an average volume of nearly 2,300 cubic feet per acre. The data in this report are based on visits to 1,100 plots located across Vermont and 1,091 plots located across New Hampshire. Forest land is dominated by the maple/beech/birch forest-type group, which occupies 60 percent of total forest land area.
Long-Term Effects of Forest Liming on Soil, Soil Leachate, and Foliage Chemistry in Northern Pennsylvania
Sugar maple (Acer saccharum Marsh.) decline disease, decreased growth, and regeneration failure have been related to a low supply of Ca and Mg. There is increased interest in augmenting cation availability via liming, but there is little information on the amounts of lime required and the longevity of the lime treatment. A single application of 22.4 Mg ha-1 of dolomitic limestone in 1985 at four forested sites in Potter County, PA has shown that soil, soil water, and sugar maple foliage chemistry are significantly altered by liming and the changes in soils and foliage persist as long as 21-yr post-treatment. By 2001, only 3 kg ha-1 of lime remained undissolved while increases in exchangeable Ca and Mg, and pH continued through 2006 at depths up to 35 to 45 cm.
2014 -15 Maple Tubing Research
In 2014 and 2015 the focus of the tubing and taphole sanitation research changed dramatically. Tests conducted in 2013 showed that if the spout and drop line were adequately sanitized sap yield comparable to a new spout and drop could be obtained. With the assistance of a grant from the Northeast Sustainable Agriculture Research and Extension program of the USDA and in cooperation with the Proctor Maple Research Center in Vermont, a variety of spout and drop cleaning and replacement options were tested to determine the extent of sap yield changes.
Could Maple Syrup Help Cut Use of Antibiotics?
Recent findings, published in the journal Applied and Environmental Microbiology, suggest that combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage.
2015 3/16″ Maple Tubing Cooperator Trial
During the 2015 maple sap season the Cornell Maple Program conducted a small trial, testing sap yield from 5/16″ tubing vs. 3/16″ tubing. This trial was not conducted at the Arnot Research forest but with a small maple operation cooperator. The tubing system consisted of six lateral lines, three 5/16″ and three 3/16″ alternating between the two treatments across the hillside.

Asian Longhorned Beetle (Coleoptera: Cerambycidae), an Introduced Pest of Maple and Other Hardwood Trees in North America and Europe
The Asian longhorned beetle, Anoplophora glabripennis (Motschulsky), threatens urban and forest hardwood trees both where introduced and in parts of its native range. Native to Asia, this beetle has hitchhiked several times in infested wood packaging used in international trade, and has established breeding populations in five U.S. states, Canada, and at least 11 countries in Europe. It has a broad host range for a cerambycid that attacks living trees, but in the introduced ranges it prefers maples. Identification, classification, and life history of this insect are reviewed here. Eradication is the goal where it has been introduced, which requires detection of infested trees using several approaches, including ground and tree-climbing surveys. Several agencies and researchers in the United States and Europe are evaluating the use of pheromone- and kairomone-baited traps. Control options beyond cutting down infested trees are limited.
