“The Temperate Interior West Community Tree Guide: Benefits, Costs and Strategic Planting” is the latest in a series of nine publications showing how trees improve air quality, conserve energy, filter storm water and reduce carbon dioxide in the nation’s cities.
The regional guides detail costs and benefits of planting trees in specific climate zones across the country. They can be downloaded for free at: http://www.fs.fed.us/psw/programs/cufr/tree_guides
Tree advocates, arborists and public officials have used the guides since 1999 to increase public awareness and support for tree programs by quantifying the average annual net benefits of trees.
Center for Urban Forest Research scientists found energy conservation to be the most significant benefit provided by urban trees in the temperate interior West. A mature hardwood tree in this region can bring annual savings of $40 in electricity and $15 in heating costs, while reducing power plant emissions through energy conservation.
Scientists also found the same tree absorbs about 6 pounds of air pollutants and intercepts 2,100 gallons of storm water each year. It also sequesters several tons of carbon dioxide, and provides about $1,100 in aesthetic, social and economic benefits in its life.
The average annual benefit of trees in the temperate interior West differs with size and location. After taking maintenance costs into account, scientists found net benefits to be:

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
