ReLeaf Michigan helps organize tree plantings across the state, and now it’s asking Michiganders to be a part of their work by competing in the Michigan Big Tree Hunt contest. The contest has been happening biennially since it started in 1993.

The idea behind the contest is to help ReLeaf account for the types of trees in Michigan along with the number and size of those trees. Awards will be handed out to the biggest trees found in each Michigan county. All trees that are submitted will need to be alive and available for verification by an official with the contest. The size of the tree will be measured by the circumference of the trunk.
