Idaho's Registry of Champion Big Trees 06.13.2019 Yvonne Barkley, Director Idaho Big Tree Program TEL: (208) 885-7718; Email: [email protected]

The Idaho Big Tree Program is part of a national program to locate, measure, and recognize the largest individual tree of each species in Idaho. The nominator(s) and owner(s) are recognized with a certificate, and the owners are encouraged to help protect the tree. Most states, including Idaho, keep records of state champion trees and forward contenders to the national program. To search the National Registry of Champion Big Trees, go to http://www.americanforests.org/bigtrees/bigtrees- search/

The National Big Tree program defines trees as woody plants that have one erect perennial stem or trunk at least 9½ inches in circumference at DBH, with a definitively formed crown of foliage and at least 13 feet in height. There are more than 870 species and varieties eligible for the National Register of Big Trees. Hybrids, minor varieties, and cultivars are excluded from the National listing but all but cultivars are accepted for the Idaho listing. The currently accepted scientific and common names are from the USDA Plants Database (PLANTS) http://plants.usda.gov/java/ and the Integrated Taxonomic Information System (ITIS) http://www.itis.gov/

Champion trees status is awarded using a point system. To calculate a tree’s total point value, American Forests uses the following equation: Trunk circumference (inches) + height (feet) + ¼ average crown spread (feet) = total points. The registered champion tree is the one in the nation with the most points. The tree with the most total points is crowned national champion. When multiple candidates exist, the new “3 x 3” rule is employed, meaning co-champions are crowned using the following criteria: if the trees are under 100 points and within 3 points; if the trees have more than 100 points and the differential is 3 percent of the total. The final register is released each year in July. Champions listed in the National Registry must be re- measured every 10 years to maintain their National Big Tree Champion status. Idaho Champion trees will retain their status until another nomination topples the reigning champ or the reigning champ dies.

Species that have BOTH Idaho AND National Champion status are in bold Non-native/Cultivated species in Idaho are indicated by GRAY shading
