"Let every tree lover, every forester, every lumberman rally…to fight for the preservation of our biggest tree specimens." Joseph Stearns, Forester, 1940

AMERICAN FORESTS' National Register of Big Trees capture our imagination for their size and strength . Since 1940 citizens have helped American Forests find the largest of 826 species of trees in the US those champions are listed on the National Register of Big Trees.

But there’s more to a champion than just its size. Big trees are symbols of all the good work trees do for the quality of the environment-and our quality of life. Big Trees provide more cooling shade and more places for wildlife to perch and nest. They sequester more carbon dioxide, trap more pollutants, and clean more of the air and water.

Although trees often outlive us, they succumb to age, disease and insects, wind, rain, drought-all , all to often, the chainsaw buzz of development. It’s our responsibility to maintain a healthy environment that allows trees to grown to champion status.
