White Noise September 22, 2010
I live 500 yards from train tracks and 5 miles from a major highway.
The train typically whistles and rumbles, bumping along the track in a forceful, metal grinding push. The highway, in the meantime, sends out the normal grumbling hum-drum of heavy traffic as semi trucks move large loads, small automobiles whiz by them and occasional construction crews jack hammer.
Noise. It has been known to cause anxiety, tension or even illness, and prolonged exposure to high levels of noise can cause hearing loss, the USDA National Agroforestry Center says in its report "Leaf the Noise Out." Today, some people even regard noise as a form of environmental pollution. Yet, noise is a part of everyday life.Read More
From Research to Reality September 15, 2010
Have you ever sat and watched a tree swaying in the wind? Sure, many of us have on a nice, cool, summer day. Now imagine studying that tree's canopy movement using 3-D motion tracking - like a video game showing how a tree, its branch structure and leaves billow in the breeze, analyzing each fraction of movement.
And what if this type of tool can actually help you determine how stable that tree really is when it's being shaken by air currents or even how much strength is sacrificed in the process?
What could this do for an arborist? A lot. It can help them better assess safety risks when climbing and pruning a tree. It can even help them determine the entire pruning plan to do what's necessary to restore or retain that tree's normal strength. What does this do for you - the person enjoying the tree on a daily basis? Even more. It means you get to watch that tree grow happier and healthier and stronger for a longer period of time, adding value to a property and providing all the benefits for which trees are best known.Read More

Get outdoors and experience nature - it's in our blood.
"An affinity for nature is in our genes," explains R.J. Laverne, The Davey Tree Expert Co.'s manager of education and training. "There's something inside each one of us - whether it's evolutionary and tied to genes or spiritual and tied to Mother Nature. Whatever happens, there is a draw for most humans to be attached in some way to nature. Whether it's conscious or subconscious, we don't understand why, but it feels good."
And, in fact, a lack of connection with nature could be detrimental to our health.Read More
