Miami University (OH) - Measuring Girth

Post by Matt Markworth » Wed May 08, 2013 7:58 pm

Hi All,

Founded in 1809, Miami University holds a longstanding reputation for its excellence in education and it's scenery. It's Georgian Revival architecture provides a great backdrop for the trees on campus. The surrounding Miami Natural Areas also contain impressive trees and boast 15 miles of hiking trails. Robert Frost visited many times and called it "the most beautiful campus that ever was."

I'm going to do a Rucker Girth Index of at least 20 species, including the campus and the surrounding Natural Areas. Here are a few trees I measured to get it started. Let me know your thoughts on whether the CBH of the Osage Orange should be included in the Rucker Girth Index. I've included photos showing the different sides of the trunk walking clockwise around the tree. The tree has been reported with an age of 210 years.

Matt,

That Osage orange defies description. I've never seen one to match it. I have a new appreciation for the species. According to descriptions I've read, the wood burns hotter than any other American species. Native Americans used it to make bows. And none of use want to get hit in the head of its falling fruit.

Bob,

Isn't that the truth. There is a row of Osage Orange along my back property line and fortunately I haven't been hit yet :) I can attest to the wood burning hot and long. The power company periodically trims them and I have some branches for an occasional fire.

The Osage Orange must be the one in front of the dining hall in the east quad. In Dr. Eshbaugh's dendrology class, in 1972, we learned Osage Orange based on this tree---but the test plant ID was from a clipped hedge of Osage Orange along S. Patterson Street in front of Upham Hall. I got it right on the test.

Matt,

I'm especially impressed with the beech. We don't get to see big American beeches here in New England any more because of the beech blight.

Hi All,

Here are more trees at Miami, along with a Rucker 10 Girth Index and a Rucker 15 Girth Index. It should be noted that I'm combining Open-grown, Forest, and Creek-side trees at the University, so comparisons to other sites aren't extremely meaningful unless these various habitats are present.

Matt-

There are a few other exotic species at Miami that are likely Ohio records: Juglans ailantifolia, near the small greenhouse attached to Upham Hall, Quercus nigra, near the NE corner of Upham Hall as I remember, and Kalopanax pictus, in the formal gardens area.

Steve,

I didn't have any luck finding the exotics. They are modifying some buildings including Gaskill Hall right next to the Upham Hall Greenhouse, and creating a new student center. With all the construction, I'm not sure if the Japanese Walnut is still standing. I'll keep a lookout for the other two.

All,

Here are more species to round out the Rucker 25 Girth Index . . .
