Silvics of North America: Hardwoods

Silvics of North America describes the silvical characteristics of about 200 conifers and hardwood trees in the conterminous United States, Alaska, Hawaii, and Puerto Rico. Individual articles were researched and written by knowledgeable Forest Service, university, and cooperating scientists. They were reviewed by their counterparts in research and academia. The project took 10 years to complete. The revised manual retains all of the essential material from the original publication, plus new information accumulated over the past quarter of a century. It promises to serve as a useful reference and teaching tool for researchers, educators, and practicing foresters both within the United States and abroad.

Invasive species, climate change, poor forest management, and other factors are all serious threats to the productivity of harvesting maple sugar in the decades to come. However, there are things we can do to protect the tradition of maple sugaring in our regions. Silviculture is our primary tool.

Soil Base Saturation Combines with Beech Bark Disease to Influence Composition and Structure of Sugar Maple-Beech Forests in an Acid Rain-Impacted Region

Sugar maple, an abundant and highly valued tree species in eastern North America, has experienced decline from soil calcium (Ca) depletion by acidic deposition, while beech, which often coexists with sugar maple, has been afflicted with beech bark disease (BBD) over the same period. To investigate how variations in soil base saturation combine with effects of BBD in influencing stand composition and structure, measurements of soils, canopy, subcanopy, and seedlings were taken in 21 watersheds in the Adirondack region of NY (USA), where sugar maple and beech were the predominant canopy species and base saturation of the upper B horizon ranged from 4.4 to 67%.

Some Background on the Asian Longhorned Beetle

The beetles were first discovered in Brooklyn, New York in 1996 and spread to neighboring Queens, infesting areas in Sunnyside, Woodside, Astoria, Long Island City, Maspeth, Ridgewood and later in Bayside and Flushing. Small infestations were also found in Flushing Meadows Park, Forest Park in Woodhaven and Kew Gardens Hills. New York city has lost over 4,000 trees because infested ones have to be cut down, chipped and burned.

Spotted Lanternfly: A New Sugarbush Threat

A new foreign invader could have a substantially negative impact on the eastern North American hardwoods in general, and sugarbushes in particular. The Spotted Lanternfly (Lycorma delicatula, SLF) was first detected near Philadelphia, PA in 2014 and since has spread throughout much of the Commonwealth and has been sighted in about a half dozen New York counties and in several sites in southern New England.
