On April 30 a new state champion was added to the Michigan Big Tree Register. The eastern red cedar, Juniperus virginiana, was nominated by Austin Patrie, and it's measurements certified by Don Carra. The tree is located in the Kleinstuck Preserve in Kalamazoo county.
Its key measurements were girth of 133 inches, height of 101 feet, and average crown spread of 47 feet, for a total point score of 246. This far outdistances the previous champion, which scored 186 points, and is located in the Portland State Game Area. There are a total of 10 eastern red cedars on the current register.
For the past 65 years, the Michigan Botanical Club has maintained a scientific register of the largest trees of each species in the State of Michigan. Paul Thompson began this work and over the course of his 45 year tenure as Big Tree Coordinator, he personally measured and documented over 4000 trees. Paul was a visionary in this field. and our register is one of the oldest in the nation. Upon Paul's passing, Dr. Elwood "Woody" Ehrle became the new coordinator. Woody spent the first two years diligently sorting and organizing Paul's notes and records, and it was under his guidance that the first official register was published. In 2008 Andy Sawyer was appointed the Big Tree Coordinator. In 2017, Andy passed the reigns to our current Big Tree Coordinator, Ted Reuschel.

The Michigan Big Tree Register
The Michigan Big Tree register is important for several reasons. First it is a vital record of a precious natural resource. These trees are typically the oldest of their type, and therefore their genetic material is also the oldest and may play a critical role in species preservation. These trees are also growing at the physiological limit for their species, and if global climate change is occurring these trees will likely be the first to be affected. The register is also important because humans have always enjoyed a close relationship with trees. Many of us had a favorite tree from our childhood, a tree that provided shade, adventure, inspiration, or recreation. Trees have also been central to our history and our faith. Consider the metaphors of the "Tree of Life", "Our Family Tree", or "Our Roots", or the role that council trees and trail marker trees have played in our history. The register stands as a record of grand examples of these historically, spiritually, and personally important trees
