Minnesota's Big Tree Registry

Your nomination must be one of Minnesota's 52 native tree species listed in the registry. All categories of information must be completed for your application form to be accepted. Local federal, state, county, or city foresters can help you verify your tree's species and measurements. Try a local nursery or tree care company for help, too.

1. Measure your tree

While measuring your tree, also get a photo and data needed to complete the nomination form.

  • County where found
  • City (or closest city)
  • Condition of tree
  • Comments (to help identify the tree)
  • Location of Tree
    • Address, City, Zip
    • GPS Coordinates
    • Detailed directions to tree
  • Date measured
  • Owner of tree

2. Check to see if your tree matches or is larger than the current champions.

3. Fill out the application form

A photo is required for a tree to be considered for the National Big Tree Registry.

You will be notified if your tree is the new champion. Nominated trees that do not surpass the recorded champion are filed as "contenders." When a champion falls, the largest contender of that tree species becomes the new champion.
