The National Register of Big Trees 2008.

The quest for champion trees and the thrill of discovering these giants has captured many hearts since the National Register of Big Trees' inception in 1940. We hope the 2008 Register will accurately document the champions uncovered through many searches. To improve the list's accuracy, this year we incorporate a new rule: All trees must be measured within the last 10 years to retain championship status. Special thanks to all the state coordinators, big tree hunters, and volunteers who put in so many hours to remeasure many of our champion trees. We did make special allowances for a few trees that big tree coordinators were unable to re-measure in time due to extenuating circumstances, including weather. Those trees will be remeasured before the 2010 Register. This Register also includes a new rounding system. Point totals are rounded up if the measurement ends in 0.50, left as is if it is 0.49. This has affected a number of trees, but only by one point. The 2010 National Register of Big Trees will include a revised list of eligible species. Please visit our website at www.americanforests.org to view the eligible species list and to use our online nomination form. May the champions in this Register--the biggest of the big--continue to fill you with amazement and inspire you to care for all trees.
