Wissahickon Valley Park 11/2019

20191106_151458.jpg In November of 2019 had the chance to visit the Wissahickon Valley section of Fairmont Park in Philadelphia. I had hoped to visit Brandywine Park in DE to seek out some tall liDAR hits Michael Taylor processed, but it didn't pan out- the ready accessibility of Fairmont made it a...

Re: First State National Monument

George, These Black Oak heights really stand out. Do you think the mid-atlantic coastal plain uplands are perhaps the optimal growth habitat for this species? I'll be popping into Brandwine and surroundings in a couple weeks seeking some of those liDAR hits Michael processed- I see you noted some of...

Zoar Valley Slope Habitats

R0017707.jpg When the WNY Old Growth Survey team sought to determine whether old-growth forest was in fact present in Zoar Valley, it was not the towering canopy of the canyon bottom that they first confirmed to contain ancient trees. Instead, the stands of often less-impressive trees lining the ca...

Re: Pharaoh Lake Wilderness, Essex & Warren Counties, NY

That's very interesting information regarding the age of the fallen pines. I think that with regards to bark character development we still have a lot to figure out in terms of cork cambium growth rate vs. diameter growth rate vs. weathering rate, and how different combinations of those parameters c...

Re: ENTS racks up 10,000 Spam emails to my gmail !! LOL

It's definitely been an unpredictable several months for the BBS. You are much more popular than I am with the spammers (I've only ever gotten one!) but I was having the same issue with the error messages- this only seemed to make the front page unusable, whereas if I searched subforums externally t...

Re: An Ode to the Bradford Pear

Josh, Speaking to NYC and WNY, you're correct in thinking that callery pear (or generally fertile backcrosses with other pear varieties, as in theory Callerys should all be one sex, hence their being labeled as "sterile," which is clearly not the case) is most noticeably and successfully invasive in...

Re: Highland Park, Rochester, NY May 3, 2015

Elijah, Thanks for the additional notes and images. I've encountered Q. prinoides in its more typical natural habitat on the atlantic coast where it's more of a ground-level scrub species, and in that setting the pseudo-bristle lobes aren't always well developed, so the leaf shape resemblance can go...

Re: Highland Park, Rochester, NY May 3, 2015

Yes, I misread. Still impressive as a single-trunk! How obvious is the difference between Dwarf Chinkapin Oak and a stunted Chestnut Oak in person? There were some references to Dwarf Chinkapin Oak on the slopes of stunted chestnut oak in zoar valley from the Diggins/Kershner era, but some of the tr...

Re: A super gnarly Live Oak

Addy, Thanks for posting- that really does have some serious gnarl factor. The subject of live oak ages has come up often in tree-interest groups on facebook recently, with of course the usual silly claims like the angel oak being 1500 years old, or even a tree somewhere in florida claimed to be 250...

Re: Hawthorn Books

Elijah, It's been recommended to me that "Haws" by Ron Lance is one of the best texts for developing an understanding of the taxonomy and subgroups of hawthorns. It specifically deals with the species that occur in the southeast (many of which range up to our area as well), but the conceptual framew...
