You better 'be-leaf' it: The hunt is on for Michiganâs biggest tree By: Alexandra Bahou and last updated 2021-03-04 11:48:25-05 (WXYZ) â Think youâre up for the challenge of finding Michiganâs biggest tree? All you have to do is be-leaf in yourself, and enter the "Big Tree Hunt Contest." The biennial contest is hosted by ReLeaf Michigan, a statewide tree-planting and education nonprofit, which works closely with the Michigan Botanical Club on this effort. This is the organization's 15th contest where Michiganders are encouraged to set out and find the largest tree around. Ashley Laux, project forester with ReLeaf Michigan, said the biggest trees are nominated for the State Champion Tree List with a shot at making it on the official National Register of Champion Trees.
