“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 ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
