Blue Ash Database

Post by Matt Markworth » Wed Jan 06, 2016 10:25 pm


I have started a spreadsheet focused solely on the interesting blue ash:

Included are my own measurements, along with measurements that have been posted by other ents. The list currently stands at 34 trees. I'll be able to measure quite a few more open-grown blue ashes in the Bluegrass Region of KY and I also know of some forest-grown blue ashes on south-facing slopes above the Ohio River.

Fortunately Emerald Ash Borer doesn't appear to currently target this species like white ash and green ash, although I know some trees have been treated as a precaution.

Please let me know if you have additional blue ashes for the list. Here are the columns:

Form (Forest-grown or Open-grown)
CBH (ft)
Height (ft)
Average Spread (ft)
Reference (Link to the original report)
Photo Links

Here are the largest girths on the list. All of these trees are open-grown trees in the Bluegrass Region of KY. By and large they are very old trees and almost all have lost their tops. A CBH of 13' or more represents what I consider to be a large open-grown blue ash.
