I noticed you E. hemlock for the Northeast. Dale Luthringer's last measurement of the Seneca Hemlock in Cook was 147.5 feet.

Phenomenal job.

Erik, Jared, Elijah, Bob, and Larry,
I want to keep this going. I have another part of it I’m working on this week, but next week I want to get into RHI 20s for each of the eastern states. A few states might be a bit of a challenge to get 20, so an RHI 10 would do nicely. Is anyone interested in taking a few states and running with it? Some states have outliers that won’t appear on any of the Rucker list so it would involve checking most reports per state. Any help would be appreciated. Just respond with whichever states you intend to do. Thanks

Megasite Comparison

updated 9/3/20

I got a little creative with this grouping. I'm using some sites that have been used before for comparison. Some areas experience geographical overlap, so this is not a strict ranking in any sense. The Chattooga River is included in both the Southern Blue Ridge Escarpment and the Georgia Blue Ridge (and the Chattooga River). The Chattooga Watershed is more comprehensive than the Chattooga River. Mary-Del-Penn (I'm open to a better name), is a collection of parks in close proximity in and west of Philadelphia, encompassing parts of three states.

The 150-foot Norway Spruce grows in Buckland State Forest in the Berkshires of Massachusetts. In the past, it was measured by John Eichholz and later by Jared Lockwood. It needs to be re-measured, but you can carry it as 150 feet for now. It would represent Massachusetts' only entry.

Thanks for getting the numbers together! I saw that numbers were pretty up to date for New York. I wasn't going to start there because you and Erik have been all over updating New York and you've been busy with Virginia as well over the past few years. This project has been so much fun, but it will be winding down soon, and then I'll just keep up with new finds, and some older numbers may emerge. I cannot access the Google Groups posts. There are undoubtedly some good numbers for several areas ( The Smokies and Natantahala NF come to mind).

Do you have any other ideas for date projects? Summer is the best time for crunching numbers as measuring slows to a crawl.

I just wanted to add some thoughts on where I think the Megasite Ruckers are heading. I'm going to refrain from comment on The Emerald Necklace and Mary-Del-Penn, as I haven't surveyed forest in those domains with the exception of North Chagrin.

GSMNP easily has the highest Rucker, despite being smaller in area than several of the other Megasites. Much of the park is in need of remeasurement. I've spent a lot of time in the Big Creek area and will continue to do so. A few new Smokies records have been found there recently. As mind boggling as The Smokies numbers are, I see them increasing in the near future.

The Southern Blue Ridge Escarpment has been well measured over the past five years. Numbers are still increasing. Despite a number of species approaching their assumed maximums, numbers should continue to increase, just not at the same pace as they have recently.

The Cumberland Plateau is in need of remeasurement and of more measurement. Several public areas have gorges similar to Savage Gulf. Savage Gulf's trees should be taller for many species already and I would expect the other gorge sites to contribute at the very least to the RHI 20.

The Georgia Blue Ridge has a number of unmeasured wilderness sites. I don't know what will be found at these sites. Jess has kept up with LiDar, so I would assume that most of the quality sites have been checked. Numbers should still increase slightly.

Congaree NP is much smaller than the Megasites but I included it for comparison because it holds more records than anywhere outside of the Smokies. Many species have attained their maximums so I don't expect much change in the numbers. Many large trees that were champions have fallen since their discoveries. As Will has stated, Congaree grows big and grows quickly. Most species max out at 150 years or so, especially bottomland oaks. Baldcypresses live much longer, as do loblollies.

Nantahala NF is in need of remeasurement. Also, many older numbers from Google Groups are now inaccessable. Some may resurface in the near future. Nantahala's numbers are understated in what I've presented, so I can't draw too many conclusions about them.

Pisgah Ranger District has been well covered as of late but a few spots remain for remeasurement. I expect numbers to creep up slightly.

Grandfather Ranger District is still undermeasured. I hope to remedy that next year but it will depend on how much time I have as the best spots are long hikes into and out of.

The Chattoga Watershed is well measured. Some of the tallest species may inch upward a bit. I would expect the supporting RHI 20 trees to increase more than the RHI 5 trees.

This next list is for the Eastern US Rucker. I do not know that these are all current as some measurers have not been posting recently. This is the best that I can come up with at this time. I've gone over all of the posts and consulted the Maxlist and various other state maxlists. I do know of a couple of species that have higher numbers but I don't have the information so they will be updated when I receive the info.

I'll start with trees native to the US and Canada, then follow it up with an exotic list and then a combined one. I'm moving the hybrids to a list on this same entry.

Great job! BTW, not that it matters, but John Eichholz and I share the credit for the bigtooth aspen in MTSF. It was my original discovery and was once 126.5 feet tall. Subsequently, its crown began to die back. Wh en John got to it, it was down to 126, and continued dropping from there.
