Everyone is invited to join the search for Minnesota's native champion big trees.
Minnesota's Native Big Tree registry is a listing of Minnesota's 52 native trees judged to be the largest in the state.
A nominee is judged on three measurements:
- Circumference, in inches, of its trunk at 4 ½ feet above the ground.
- Its height in feet.
- One-quarter of its crown spread in feet.
The total of these measurements is the points awarded to a particular tree. A champion tree has accumulated the most points.

Did you know there is also a National Registry of Big Trees that recognizes champion trees nearly 900 species and varieties? Minnesota has one national champion included on this list – the white spruce. In fact, Minnesota's program is set up using much of the same criteria as the national program.
