It’s a good time for building with wood products. More architects and contractors are returning to this renewable, sturdy, all-purpose material after decades of what some might consider an undue reliance on concrete and steel.
In furthering that message, I was pleased to join WoodWorks, a nonprofit organization supported by a $1 million grant from the U.S. Forest Service, to host more than 350 architects and builders this year at the Wood Solutions Fair in the District of Columbia.
The fair promoted the use of wood in commercial buildings in helping maintain sustainable forest management, addressing wildfires, droughts, extreme storms and insect epidemics. Wood buildings store tremendous amounts of carbon and reduce the fossil energy needed for construction over alternatives like concrete, steel and aluminum. Read more »
Almond growers are innovative in their water savings. This orchard uses micro-irrigation, which efficiently directs water. Photo courtesy of the Almond Board.
It takes a lot of hard work to make a living out of farming, to build a thriving agricultural business and it takes ingenuity. This is especially true in rural America, where dedicated farmers and ranchers rely on each other and the communities around them to fuel innovation and create opportunity. From nutritional research to competitions that promote sustainability and continued environmental care, ag promotion programs—with oversight from USDA’s Agricultural Marketing Service (AMS)—help American farmers make long-term investments that ensure a better future for everyone.
For more than 30 years, California almond growers have pooled their resources under the Almond Board, focusing on research and techniques to make the most of precious water resources. Efficient water use and irrigation management are vital to the success of California’s Central Valley almond growers, ensuring that consumer demand for almonds can be met sustainably. State-of-the-art farming and production developments over the past two decades have helped farmers reduce the amount of water they use per pound of almonds grown by 33 percent. Key strategies have included the wide adoption of micro-irrigation as well as advances in soil assessment and monitoring. Read more »
Cross Laminated Timber (CLT) and other emerging wood technologies are being used in new construction projects around the world, like these apartment buildings in Vaxjo, Sweden. (Photo credit: Midroc Property Development)
Cross-posted from the White House Rural Council:
As part of the Obama administration’s commitment to mitigate climate change, USDA, in partnership with the Softwood Lumber Board and the Binational Softwood Lumber Council, is announcing the U.S. Tall Wood Building Prize Competition. This competitive prize, open to teams of architects, engineers, and developers, will showcase the architectural and commercial viability of advanced wood products like Cross Laminated Timber (CLT) in tall buildings.
Advanced wood products are becoming the latest innovation in tall building construction. Products like CLT are flexible, strong, and fire resistant. In construction, wood products can be used as a successful and sustainable alternative to concrete, masonry, and steel. Using wood also reduces greenhouse gas emissions by storing carbon and simultaneously offsetting emissions from conventional building materials. By some estimates, the near term use of CLT and other emerging wood technologies in buildings 7-15 stories could have the same emissions control affect as taking more than 2 million cars off the road for one year.

Several hundred non-native forest insect species have become established in the U.S. Recent arrivals, such as this adult Asian longhorned beetle, have killed millions of trees and altered urban landscapes in the Northeast and Midwest.

Wood makes great packaging material—it’s inexpensive, abundant and versatile—but there’s one drawback: destructive forest pests stowaway in the pallets, crates and dunnage (wood used to brace cargo) used in international shipping. Over many years, international trade has resulted in the inadvertent introduction of many non-native wood-feeding pests and plant pathogens in the U.S. and throughout the world. Some of these non-native insects, including the emerald ash borer and the Asian longhorned beetle, have become highly invasive and caused serious environmental and economic impacts.
But an international standard for wood packaging material is slowing the inadvertent export of invasive bark- and wood-boring insects, according to a study conducted by Robert Haack, a research entomologist with the Forest Service’s Northern Research Station in Lansing, Mich., and a team of scientists. Researchers found as much as a 52 percent drop in infestation rates in the U.S., where the standard was implemented in three phases between 2005 and 2006. The study was published May 14 in the journal PLOS ONE. Read more »
Harvard Forest staff renovated a pole barn to house the boiler room and modern wood shop. The new boiler room (left side of the building) contains three wood gasification boilers, a 2,500-gallon thermal storage tank, a propane-fired backup boiler and associated pumps and system controls. The sloped roof on the left of the building provides a dry storage area for racks of firewood prior to loading in the boilers. (U.S. Forest Service/Rob Clark)
I recently had the opportunity to speak at the dedication ceremony for the Harvard Forest Wood Energy Project, an exciting venture partially supported by the U.S. Forest Service Northeastern Area. This woody-biomass heating system will support 50,000 square feet of the central campus buildings and five dormitories, replacing fuel-oil with renewable firewood that comes from Harvard Forest, a 3,500-acre laboratory and classroom in Petersham, Mass., and owned by Harvard University.
A unique aspect of this project is that it is at the heart of a long-term forest carbon research project. Not only are carbon flows in the Harvard Forest where the wood for the new energy system will come from already being closely studied, but now every aspect of the new installation will be very closely monitored and studied as well.

Imagine nearing the remote, rugged crest of the Gallatin Range in Montana’s Gallatin National Forest. As you scramble up-slope, you put your hand against what appears to be a lightning-blasted stump for balance. But the stump is not weather-polished wood—it’s made of stone.
These are the 50-million-year-old remains of redwoods, pines and sycamores which make up the Gallatin Petrified Forest, where fossilized tree trunks are preserved in so much detail that cellular structures may be seen under a microscope and growth rings are often visible to the naked eye. But how did these trees turn to stone? Read more »
