BACKGROUND EuroAmerican land-use and its legacies have transformed forest structure and composition across the United States (US). More accurate reconstructions of historical states are critical to understanding the processes governing past, current, and future forest dynamics. Here we present new gridded (8x8km) reconstructions of pre-settlement (1800s) forest composition and structure from th...

the impact of climatic variations on basal area growth of basswood (ba) (tilia americana l.), american beech (be) (fagus grandifolia enrh.), bitternut hickory (bh) (caria cordiformis (wang.) k. koch), largetooth aspen (la) (populus grandidentata michx.), red maple (rm) (acer rubrum l.), red oak (ro) (quercus rubra l.), sugar maple (sm) (acer saccharum marsh.), and white ash (wa) (fraxinus a...

Mark Schafer President and Principal Scientist, Sonic Tech Wayne, PA This paper presented the results of several years of testing the use of ultrasound to find structural defects in pallet parts and pallet cants used to produce pallet parts. To determine the magnitude of unsound defects, we inspected full length cants from seven saw mills from Virginia and West Virginia. Split, wane, shake, hol...

This paper will discuss the evolution of the treatment for a 1751 French boiserie mirror retaining approximately 30% of its original gilding. In the first phase of the treatment, the mirror had been thoroughly analyzed and documented, tests were undertaken and cleaning and compensation method testing had commenced. This philosophical discussion was presented in a paper in the general session la...

St. John’s is a “landscape paradise” in central Minnesota. Although no complete checklist of vegetation exists for the campus, various surveys reveal a diverse flora. This floral wealth is the result of several terrestrial biomes (Figure 1) converging on campus – prairie, savanna, deciduous forest, and coniferous forest – as well as diverse aquatic habitats including both lakes and wetlands. A ...

The Virginia landscape supports a remarkable diversity of forests, from maritime dune woodlands, swamp forests, and pine savannas of the Atlantic Coastal Plain, to post-agricultural pine-hardwood forests of the Piedmont, to mixed oak, mesophytic, northern hardwood, and high elevation spruce-fir forests across three mountain provinces in western parts of the state. Virginia’s forests also have b...
