Did you know that Minnesota has a Big Tree registry that lists the state and national champion of different tree species? Anyone can nominate a tree!
Large trees are awarded points based on a total of:
- The circumference in inches, measured at 4.5 feet above ground
- Its height in feet
- ¼ of its crown in feet
Based on this point system, the largest tree in Minnesota is the Eastern Cottonwood which has a total point value of 527.5. (Circumference: 394″, Height: 106′, Crown spread: 110′). It is located in Chippewa County near Watson.
Our largest National Champion tree is a Black Willow located near St. Croix River.
