Last October,we received the final copy of a study we <br /> participated in that used American Forests' CITYgreen software to analyze aerial photos and <br /> satellite imagery from 1972 and 2001 to detail how the forest canopy cover in the Willamette <br /> Valley has changed over the last several decades. The software, which we used in a pilot project <br /> during the code revision process a few years ago, also calculates, in dollar figures, the benefits <br /> that tree canopy provides, such as air pollution reduction, carbon sequestration, and water quality <br /> improvement. <br /> Our partners in the"Regional Ecosystem Analysis for the Willamette/Lower Columbia Region <br /> of Northwestern Oregon and Southwestern Washington State"included the USFS, ODF, <br /> Washington State Department of Natural Resources, and the cities of Albany, Beaverton, <br /> Corvallis, Portland, Salem, Tualitin, Vancouver and Wilsonville. Major findings show that <br /> average tree cover in the Willamette Valley has decreased from 46% in 1972 to 24%in 2001. <br /> Contact me by phone or by e-mail [mark.r.snyderci.eugene.or.us] to receive a copy of the final <br /> report. In the meantime, you can look at this news, once again, as an opportunity to talk with <br /> your customers about all the good reasons to plant trees and take care of them properly for the <br /> best environmental benefits,benefits that can translate directly into dollars in their pockets! <br /> (100 <br /> Coy <br />
