America's Big, Champion Tree Registry

First founded in 1875, American Forests is the oldest national nonprofit conservation organization in the United States. Recently AF completed the latest National Register of Big and Champion Trees for 2006-2007.

American Forests has been the keeper of the register since 1940 when forester Joseph Stearns said: "Let every tree lover, every forester, every lumberman rally ... to fight for the preservation of our biggest tree specimens." Since then, the register has turned into an institution with big tree coordinators in all 50 states and a group of big tree hunters always on the lookout for new champion trees.

Most states have big tree or champion tree programs and publish their own lists (I nominated the largest Alabama champion black willow and it still stands today). "The competition among states and big tree hunters often is fierce" according to American Forests. "Especially when the title for an official State Tree is held by a different state." These "hunters" are out to dethrone the national trees of record with their own nominations. They even remeasure existing ones to challenge any errors that might have been made.

These champion trees are measured mostly by foresters, rangers, or big tree hunters who submit nominations to the American Forests Register or the state big tree coordinators. A free brochure with rules for measuring and nominating trees is available from American Forests or through your state forester.

There are 826 native and naturalized species eligible for inclusion in the Big Tree Register. Eligible trees must be native or naturalized in the continental United States (including Alaska, but not Hawaii). They are listed in Check List of Native & Naturalized Trees of the United States, written by Dr. Elbert L. Little, Jr., former chief dendrologist of the U.S. Forest Service (see my review on his excellent tree id book).

The current list totals 889 champs and co-champs representing 738 tree species. Florida again has the most national champion’s trees (160) followed by California (101), Arizona (82), Texas (78), and Virginia (54). There are seven states that have no champion: Arkansas, Delaware, Kansas, Massachusetts, North Dakota, Oklahoma and Wyoming. The Register is available in print from American Forests Magazine or National Register of Big Trees.
