Idaho's Registry of Champion Big Trees
02.14.2017
Yvonne Barkley, Director
Idaho Big Tree Program
TEL: (208) 885-7718; E-mail: [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/bigtreessearch/
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

Abies concolor
concolor fir
(Rocky Mtn. white fir)
NOTE: Abies concolor is the accepted name in the ITIS database w. common names of concolor fir and white fir BUT NOT Rocky Mountain fir.
Unfortunately the National BIG tree program database is using the combination of Abies concolor and Rocky Mountain white fir together – a query
to the National Director resulted in the following response “Abies concolor var. concolor has not been presented to us as a new species, so we have
not changed the database. I can’t verify which variety is the champion for 2016 is, but it is located in Utah so I would assume Rocky Mountain white
fir.”
