Re: Is this the largest single-stemmed tree in PA, and the largest sycamore in the U.S?

Bee, Not sure. The extremely dense woods like live oak will weigh more, of course. Conifers like pine will be less. It gets complicated because of the different densities of dry wood and bark and the varying moisture contents in the trunks within a species and across species. What further complicate...

Re: Is this the largest single-stemmed tree in PA, and the largest sycamore in the U.S?

Bee, Using the FIA-COLE volume-biomass model, the predicted volume is 3,754.5 ft^3. Unquestionably, other academic-Forest Service models would yield different results. However, the total volume is not likely to be under 3,200 ft^3, and probably not as much as FIA-COLE predicts, which applies more to...

Re: Ragged Mountain Natural Area, Charlottesville, VA

Elijah,

That 175-foot tulip may be the tallest accurately measured tree in Virginia. I know Eric Wiseman has one elsewhere at 172, if I remember correctly. I'll ask Eric.

Brian,

I would love to see that mountain laurel snaking its way along the ground for 35 feet. Wild!

Re: An update and report on the Penn trees in "Penn's Woods 1682-1982"

Bee Great job. Very interesting information. The American sycamore performs spectacularly in the big tree competitions, then and now. I am impressed by the number of white oaks on the lists. Comments on trees that were assumed to be part of the original forest are interesting, and potentially reveal...

Re: Is this the world's longest branch?

Ride,

I'm not sure either. I'll ask BVP and get a definite answer.

Re: Big Trees of Columbia County NY

Brian, Good finds. Sooo many possibilities. BTW, as you search the countryside for impressive trees, if you would like to include a volume measurement for the trees to go along with the usual 3 dimensions and point total, let me know, and I can try to supply it for quite a few species. I would use t...

Re: Undiscovered Old-Growth near Woodward PA??

Ents,

Using photographic analysis, the white pine in the Tioga Tract appears to be 196 feet tall assuming the person at the base is 5' 10". No way of knowing. There's probably another 5 to 10 feet of foliage. Trees of that age usually have flattened tops. So, don't expect a lot more.

Re: Pisgah National Forest, Davidson River Area, NC

Brian, At the base, I'm trying to show to a number of forest scientists, if crudely, what white pines are achieving growth-wise from Canada to Georgia, starting from the top and working down. Thanks to you, Jess Riddle, and a few others, there is a steadily growing number of sites in the southern Ap...

Re: Pisgah National Forest, Davidson River Area, NC

Brian,

How much white pine is in that area? Are there a lot of 150s?. In the paper I’m a coauthor on with several climate scientists, we’re listing outstanding white pine sites. In your judgement, would this one qualify? If sp, I’d like to list it.
