Wander Indiana . . .

After spending the better part of a morning trying to locate tops in a dense flatwood forest, I decided to change up my strategy and find some elevation. I headed over to Hemlock Bluff Nature Preserve in Jackson County, IN and was not disappointed.

The description claims that the preserve contains the largest Hemlock in Indiana at 33” DBH. It may be referring to the same tree that I measured at 8.4’ CBH with a height of 108.9’. That claim appears to be dated though, as the 2010 Indiana Big Tree Register has a Hemlock with a CBH of 9.4’ and a height of 135’.

By the way, thanks for allowing someone with no formal “dendro” background hang out with you guys/gals. It’s a testament to your hospitality and graciousness.

Matt,

This is one site I always wanted to visit. Thanks for the information. It is an unusual disjunct population of eastern hemlock and I have always wondered about how much genetic variation there might be in this population compared to nearby continuous populations.
