Keep in mind that the Oregon champion registry is based on a point system that combines height, trunk diameter and average crown spread. The species nominated and listed may not necessarily be the actual largest, or the tallest.

For example, in 2011, we found 4 Ponderosa pines, all of which were new world's tallest pines: of any pine species. But we did not nominate them, because they did not have sufficient points to beat the Ponderosa pine champion.

January 2011 Tallest Pine Discovery

But each one of the four pines were indisputably the tallest known pines in January 2011. Each one of the four was taller than the previous height record.

And that's the way this registry and nominations works. The standard is controlled by American Forests. It does not ensure a registery of the actual biggest trunk or tallest canopy.

But, basically everything on the list is still impressively large for its species.

The responsibility for keeping track of nominations and measurements was shifted to volunteers or non-profits.

To submit a nomination, acquire the following information:

Circumference
Height
Crown spread
Common and scientific name
Date measured and by whom
Exact location (GPS and map)
Owner's name and address
Nominator's name and address
Any additional information

Outside Oregon, look on the American Forests site for your state's register:
