American Forests is proud to announce the new species list for The National Register of Big Trees in 2010. There are 57 new tree species that are eligible for nomination in the register, while 22 species have been removed. The new tree species are denoted by an asterisk beside their name.

Our goal has always been to ensure the scientific integrity of tree species so that they are in accordance with today's taxonomy and nomenclature. These changes have been made to help achieve that goal, while continuing to best reflect Dr. Elbert Little Jr.'s 1979 publication of native and naturalized species in the United States, upon which the register is currently based.
