George,
The hackberry is off the charts. I've observed the species from Massachusetts to Iowa and measured them up to a little over 90 feet, but your hackberry is in a new class. The site index is quite respectable.

Great job, George!!! That hackberry blows away the rest in terms in height. That'll be a tough one to beat. Your honey locust and Norway maple are the tallest documented in PA... but we have very few in the database, so these could change. Sorry it's taken me so long to reply. I'm slowly getting to my data backlog and wanted to get this in my list of PA RI sites. Thanks!

The preserve has a total of 67 acres containing open fields, flood plain, and wooded areas on steep slopes overlooking two streams, Cedar Hollow Run and Valley Creek. This site has lots of invasives with the slopes and ridges having little to none. The preserve was once a farm site and the old fields are full of honey locust. Church Rd. runs through the preserve dividing it into two sections, east and west. The east side is mostly open field and flood plain while the west side is completely wooded. The first tree we measured was a huge sycamore just south of the parking lot. It is the largest tree on the preserve at 19’5” x 107.2 x 119.5. This is the largest sycamore of four that had a 14’+ cbh. We then crossed Church Rd. and headed into the west side of the preserve. Tulip poplars dominate the canopy along with ash(green or white), red oak, sugar maple, and fewer bitternut hickory. Halfway up the north slope was a large fallen red oak with a 15’+ cbh. From here we walked the top of the ridge to the southwest corner of the preserve where we found an eastern red cedar. From where I stood the tree looked dead but it’s top was green. A closer look revealed that one side of the trunk had no bark but the back side did. It reminds me of a bristle cone pine. The cedar measured 6’1” x 48. Then we headed back, northeast along the ridge, and came across a small flat that had a few chinkapin oaks. Just below the flat was a fat bitternut hickory that measured 8’2” x 99.9. We were now on the south facing slope and found some more bitternut hickories and the tallest was 6’9” x 114.4. We measured a few more trees before crossing back over Church Rd. and into the east side of the preserve. The east side is dominated by honey locust along with boxelder, black walnut, sycamore, and ash except for a small ridge in the northeast corner that has the same forest type as the west side of the preserve. Here we came across some short but fat honey locust. The largest cbh was 10’8”. We followed the stream, measuring a couple of fat sycamores along the way, crossing the creek and up into the small ridge. Along this ridge is a huge common hackberry( I made an earlier post about this tree). It measures 12’3” x 114.2 which makes it a new northeast height record. I measured one or two more trees before getting back to the truck. Another great day in the woods! Here are the measurements for Cedar Hollow Preserve.
