Fantastic post! The NTS measuring mission at its best. In terms of tallest accurately measured hemlock in Michigan. If I recall, Will and I measured some in the Porkies to approaching 116 feet.

More later. Monica and I are on the road in western Tennessee headed west.

Bob,

can't wait to hear more about the hemlocks you guys measured in the Porkies. I imagine the species will fairly easily break 120' in MI but I'm not sure beyond that. I saw several 100'+ hemlocks in Hartwick Pines and at least one or two more that were likely over 110'.

Doug,

I'm glad you were finally able to spend some time measuring trees at Hartwick Pines. I enjoyed reading your report very much. Congratulations on the tallest red pine! Your photograph of the tallest white pine (whole tree) that I measured in September of 2013 really shows its great height.

I was questioning my height measurements some back in 2013 when I measured trees in Hartwick Pines but it turned out that my measurements were quite good. It wasn't until I reached Hartwick Pines in September of 2013 that I realized I didn't have a memory card in my camera! I was hoping to get back and take photographs to accompany my post but it hasn't worked out to return.

It is unfortunate that the white pine I measured to be slightly taller at (162.86' = 163') is likely no longer standing. It stood in a low wet area and I suspect the trees in that part of the park have a very shallow root system which would make them more susceptible to blowing over. I don't think the tallest red pine you measured is the same tree as the tallest one I measured. I don't recall a hemlock at the base and the circumference and height measurements don't quite line up. The one I measured had a slightly larger trunk and at less than 148', I don't think it would have been able to make it up to the height of your tree in two growing seasons.

Here is a list of some of the trees I measured at Hartwick Pines back in September of 2013. I was using a Nikon 440 so I have rounded my heights to the nearest .5'.

Species Circumference Height Average Crown Spread Index

red pine 5'8" 147.5' ___ ___

white pine 11'4" 140' 35.5' 284.875
white pine 12' 141.5 51.5' 285.5
white pine 11'4" 142' 41.5' 288.375 This one has the greatest index of the white pines I measured.
white pine 10'4" 145.5' ___ ___
white pine 7'6.5" 148' ___ ___
white pine 10'10" 148.5' 38' 288
white pine 7'5" 152' ___ ___
white pine 8'11" 152.5' ___ ___
white pine 8' 154.5' ___ ___
white pine 8'9" 161' ___ ___ This is the tallest white pine mentioned in Doug's report.
white pine 8'11.5" 163' ___ ___ This one is likely no longer standing.

Doug- Wow congrats on the Red Pine! The White Pine is also fantastic! I measured some Red, Jack and White Pine in Mn and Wis but nothing like those babies!! Great post and some really nice photos!!!

Doug,

Awesome photos and impressive heights man!! I especially liked the 160' + tall E. White Pine photo. That was really cool.

I just lost my draft but I was commenting on how red pine grows better in northern Michigan than southern Michigan and it is very observable when planted with white pine. White pines in Kent county where I live will have 20' feet on similar planted red pines by the time they are about 90' tall or so here in southern Michigan where as the gap is much smaller in northern Michigan. Red pine is a transitional forest/boreal forest species that occupies the northern realm of the temperate forest as well and the central portion of northern Michigan is definitely in the tree's comfort zone.

Also, I just visited the Porkies and I could not find a single hemlock tree over 100 feet tall. The trees that are in the Appalachians are in contrast way larger and it appears that there is a strong relationship between precipitation/climate there and the size they attain.

Thanks -

Dan Morris

NTS,

last month I remeasured the tallest White Pine and tallest Red Pine.

May 2016
White Pine 8.86' (106.3") x 162' 2"
Red Pine 5.62' (67.4") x 151' 10"

May 2018
White Pine 8.87' (106.4") x 163' 3"
Red Pine 5.65' (67.8") x 152' 5"

So the White Pine grew 13" in height and the Red Pine grew 7" in height in two years. The White Pine needs to grow 10" to surpass the 50 meter mark so if all goes well Michigan may have a 50 meter tree in two more years.

Doug
