Minnesota's Native Big Tree Registry

A child helps a forester measure a big tree

Have you ever seen a tree and wondered if it’s the biggest tree? There’s a list for that – and your tree could be on it!

Minnesota's Native Big Tree registry is a record of Minnesota's 53 native trees judged to be the largest of their species in the state.

Nominees are judged on three measurements: circumference, height, and crown spread. Together, these measurements are used to calculate the total points awarded to a particular tree. A champion tree is the one with the highest points for its species.

Become a big tree hunter! You just need a measuring tape and ruler to get started – and maybe a friend or family member. Learn how to measure a big tree. These biggest trees can be found in forests, parks, and front yards.
