Yup, that is some sweet SWO porn.

Just thought I would add a couple of left over scraps that you might have missed. I came across a large tuliptree at 137' x 14'10" cbh which is over a foot thicker than the previous 13'8" recorded for the species . I also recorded a 118' x 4'10" Bigtooth aspen which would be a newly recorded species for the site. I found four of them near each other but do not have photos at this time.

I managed to get an average crown spread for the large pignut/red hickory that I located in the park. It has a max spread of 90ft with a perpendicular spread of 70ft for an average 80ft crown spread. The total points would be 275 which would make it the largest for the state whether or not its actually a pignut or a red. The Ohio big tree registry has a pignut listed at 230pts and a red at 262pts. I also did the numbers for the Fort Hill pignut found by Matt Markworth at 253pts and the red hickory found by Turner Sharp at Mound Cemetery in Marietta at 202.7pts.

That tulip has a fascinating and beautiful atypical form! Thanks for sharing. Good luck with the hickory ID, hopefully you can visit it when fruits are available and reasonably fresh.

Stefan,
It's almost certainly red hickory.

NTS. AF spoke method for spread is now required, FYI... Eight spoke minimum.

Quite a spread!

I went to visit the tallest recorded tree in the park last measured over five years ago with an official height of 157.3' (Reed, Galehouse, Blozan 9/5/11). After determining the mid-slope by taking the difference between the upslope and downslope relative to a wrapped ribbon around the trunk. I then readjusted the ribbon a foot higher to 4.5ft using a bubble level to make the wrap as straight as possible. I took five different measurements from five different positions after finding the tallest leader. I used the ribbon as my bottom reference and added 4.5ft to the final result. I got hits of 162.5',161.38',162.16',164.14',163.14'. The average height for the tall tulip is an unofficial 162.66'. It's growing about a foot a year.

Nice work! The highest reading is the truest height. That sucker is growing rapidly. In 5 or 6 years, it may become a member of the 170 club, only the second for northeast Ohio.

Stefan,

Brian's right. Using an accurate laser and proper math, there's no need to average your readings. Trust your tools. The highest reading, as long as it's repeatable, is the true height.

That's the thing. The top hit wasn't repeatable so far, only one hit. I need at least two hits to trust it myself, let alone for others to trust it. I think somewhere between 161 to 162 is a more repeatable height for others to achieve. My readings should be regarded more as "estimates" rather than "measurements". The latter term should be reserved for cadre tree measurers.
