Re: Letchworth State Park

Great finds. Letchworth has so much ground to cover! Have you seen any Balsam Poplar among the younger trees in successional floodplain there? It's showed up abundantly in the Chautauqua Gorge, and when I was recently there with a botanist who's going to be working on an up-to-date flora of new york...

Re: Franklin D. Roosevelt Presidential Library and Home

Was that cucumber magnolia a well-formed single stem towards the base? One of similar girth at the Montgomery estate was disappointingly just a chunky double, but I've seen photos suggesting the species can develop and excellent open-grown form under the right conditions.

Re: Opportunity to make our data count

Bob, I agree it is a slow conversation but I'm sure many of us are eager to contribute. I'm making plans for some good data collection from Allegany state park. When I look back at a lot of my past data, though, it's a bit daunting to think about how to sort through it and extract the most relevant ...

Re: Nikon Coolshot 80i VR

Don, that is a method some cheap cameras and cellphones use (it can be done better later by software that performs R-L Deconvolution sharpening, like RAWtherapee). The stabilization technology in higher end photo gear (and specifically designated by the "VR" branding in Nikon products like this) rel...

Re: Nikon Coolshot 80i VR

I would not be certain of that yet- Nikon has extensive experience in stabilizing optics (as I've appreciated in their VR camera lenses as well), and this technology is what would result in a more stable view through the eyepiece, and this is what might improve accuracy in SD measurements in reducin...

Re: Ash height record?

Very interesting. I'd be glad to hear of the current status of known White Ash height records in New England- just the other day the question came up on facebook of whether any of the ash in Mohawk Trail State Forest were still standing over 150'. Sounds like you've got an exceptional specimen not j...

Re: Big Basin - Allegany State Park

Elijah, maybe when Bob's able to head down we can make it a little rendezvous. Lots of good stuff yet to measure, and some of the larger stems would be great to model for volume. A big question in my mind- would a Rucker Volume Index for ASP be able to match an RVI for the much tinier Leolyn Grove a...

Re: Dutchess County's Champion Trees May 6 2017

Nice. Between that, the 141' tulip, the hemlock over 120' etc I am sure this site would end up on the list of NY RHI 120 sites given a thorough measuring. Looking forward to hearing about this other estate!

Re: Big Basin - Allegany State Park

Saturday 4/6 I put some miles in on the other side of ASP1, mostly across Stoddard Creek in the (more or less) southwestern quarter of the Old-Growth area defined by NYNHP in the map from the original post. From the trailhead I set off from I was able to sight another cluster of white pines in the d...

Re: Large Shumard Oak. Noxubee National Wildlife Refuge

That is some oak! Pretty large crown spread for forest-grown, too. Also really loving the photos of the spring bloom- they look to me like some golden ragwort (Packera) species? Are these (and the oak) on the floodplain itself or former floodplain that's now persistently dry?
