Re: NY Rucker Height Index

Poison sumac you'll most often find in association with wetlands with more calcium, often in areas with limestone bedrock. Often peaty wetlands that might be colloquially termed "bogs" but are technically "fens" with higher pH groundwater as one of the major sources of moisture (true bogs are built ...

Re: The Ancient Hemlock Ravines of the Canadaway Creek Drainage

Thanks Elijah. BeeEnvironment, my understanding is that at this point filling or plugging increment borer holes is considered to have no benefit and even potential to cause harm by interfering with the tree's natural processes for compartmentalizing small wounds. Most of the old trees I have cored i...

Re: Undiscovered Old-Growth near Woodward PA??

Bob, I've read through the past conversations here that made that case, but that conclusion that 220' seems like a reasonable upper limit is exactly what I've come to question. Too many of these dozens of accounts of trees measured in the process of timbering (certainly not clinometer measurements, ...

No problem. I'll include a letter with some pointers on getting started and resources for further reading and practice.

Re: Stateline Woods Preserve, off of Old Kennett Pike

Hi BeeEnvironment, This looks like a great forest site. The Oak-Tulip-Beech forests of that part of the Atlantic coast region can really put it up there. A question about your MonumentalTrees posts, though- they list that you measured the tall beeches with a laser in two-point mode? That's the measu...

Re: Galen WMA

Thanks for sharing these measurements and congrats on the 120' Bur Oak. This site and its surroundings do sound like they have great potential. I wonder what's across the river in that area with the more mature-looking canopy with heterogenous texture? Similar areas in the Conewango Swamp WMA have s...

Re: Moravian Cemetery, Staten Island

Hi Elijah, Thanks for the Magnolia suggestion. I really haven't gotten any more familiar with these nonnative trees since I posted, to be honest. I do think the leaf may be more likely F. grandifolia than sylvatica based on the lack of cilia around the edges and it was found near the cemetery edge, ...

Re: The Ancient Hemlock Ravines of the Canadaway Creek Drainage

Recently I took the time to collect a core sample from a Hemlock in the first location I posted about in this thread, the narrow ridges in the steep ravine at location "D" on the map. Previously, a section I cut from a snapped-off hemlock of modest size showed at least 291 growth rings. This newly s...

Re: Whiskey Hollow Preserve, Van Buren

That's a very impressive small site! Where they're present, hickory composition certainly does seem to be an interesting indicator of subtle differences in the abiotic conditions of a given forest's setting. Nice to hear about a site that still has a good Beech component too. Do they all seem pretty...

Re: NY Rucker Height Index

Hi Elijah, Thanks again for your continued maintenance in this authoritative list. The only thing I see that's missing is the 134.8' Black Cherry from Allegany State Park (Trackless West topic). Those exotic Abies must be hard to sort out. I try to just avert my eyes when I meet unfamiliar planted c...
