The Fort Vancouver National Historic Site worked with the Oregon State University College of Forestry and sampled every single wood member in the log stockade known as the palisade.

Two kinds of long-term research are taking place at the H. J. Andrews Experimental Forest, a renowned research facility in the temperate rain forest of the Oregon Cascades. Here, scientists investigate the ecosystem's trees, wildlife, water, and nutrients with an eye toward understanding change over varying timescales up to two hundred years or more. And writers from both literary and scientific backgrounds spend time in the forest investigating the ecological and human complexities of this remarkable and deeply studied place.
"The wood product (cross laminated timber) is incredibly strong and it can be put together incredibly big," according to Thomas Maness, a dean at the college of forestry at Oregon State University.
“For the first time in 70 years, the park has a complete suite of predators and prey,” Oregon State University forest ecologist William Ripple, a co-author on the study, told The Washington Post in 2004. “This is a grand experiment.”
At the DR Johnson plant three hours to the south—the first in the country to make structural-grade panels—the timber is planed down to a thickness of 1.375 inches, laid flat and set end to end in a single layer. Another layer is glued on top perpendicularly, then another layer glued perpendicular to that and so on—generally three layers of boards for walls and five for floors, according to Lech Muszynski, a wood science professor at Oregon State University—until it is sent into a massive custom-built press for a couple of hours while the glue sets.
Oregon State University has been notified that it will receive a $447,000 grant from the federal Economic Development Administration for the testing of cross-laminated timber, or CLT. The testing will allow the development of manufactured wood products that meet state building codes so the products can be approved for the construction of large buildings, said Geoff Huntington, director of strategic initiatives for OSU’s College of Forestry.
But while the microorganisms can be grown in solution, capturing the pigments has required the use of toxic solvents, said Sara Robinson, an assistant professor in the OSU College of Forestry. Robinson has now found a way to use oils to harvest the pigments, and OSU has applied for a provisional patent on the technique.
Panelist Steve Strauss, Oregon State University professor of forestry, took a sharper tone as he lay out of a brief history of a growing campaign against genetically modified crops.
