Re: New mission?

Hi Bob, I do think this is an important mission to be pursuing. I was not able to do as much tree measuring this last season as I had planned and would have liked to. This was largely due to a transition into full-time-ish ecology-oriented work, whereas previously this has been something I've pursue...

Re: Rucker Comparisons

Hi Brian, Just curious- is the intent to edit and update the individual state posts as time permits? I'm just noticing that in some cases the numbers used are from the older posts for a given site, rather than their most recent numbers, like Ragged Mountain in VA. I realize there's a lot of material...

Re: Letchworth State Park

Elijah, This is a fantastic outcome to the work you've done at Letchworth in the last several years. I had imagined that Letchworth probably matched or exceeded Zoar's big tree potential in presettlement times, but had not imagined it would be so close to it in the present day! Interesting to see th...

Re: Can someone help me ID this plant I found at Spirit Creek State Forest

Looks like the basal rosette of a Nicotiana species.

Re: Big Basin - Allegany State Park

On January 2nd I returned to the upper reaches of Red House Brook to explore a little more intensively and get a better sense of the extent of large old-growth hemlocks. My focus was hemlocks over 40"dbh or 110' tall. As before, the truly large hemlocks mainly occur low on the slopes and right withi...

Re: Howland's Island

Elijah, I've been using qGIS. It does a lot of what more sophisticated programs like arcGIS can do. High-resolution digital elevation tiles can be downloaded from orthos.dhses.ny.gov along with different aerial imagery sets and now liDAR for most of the state, which I keep downloading but then putti...

Re: Rockefeller State Park Preserve

I'm with Brian on that, the placement of Oak species in this Rucker reminds me more of the midatlantic site lists George Fieio posts than other sites in NY (excepting maybe Inwood Hill)- which makes sense in terms of the geography. Your surveys at this site have definitely raised the bar for Quercus...

Re: Howland's Island

Elijah, since you've got so much data from Howland's Island, have you considered mapping some of it to get a sense of how the trends you're seeing interact with the landscape from the digital bird's eye view, so to speak? I'm doing more and more mapping recently and it certainly makes me wish I had ...

Re: Big Basin - Allegany State Park

ASP's Big Basin may be easiest to define as the watershed of Red House Brook (though at the western edge it overlaps with the area I've described as the "Trackless West")- visible in this map: http://www.wnytrails.com/maps_allegany/maps_pdf/map_Allegany_watersheds.pdf The southernmost "prong" of the...

Re: Allegany State Park's Trackless West

On November 26, 2019, after some explorations in ASP's Big Basin (report pending) with Jamestown NY old-growth enthusiast Chris Merchant, we decided to use the last hour or so of daylight to go measure a White Pine that Chris discovered several years before. He had sighted its emergent crown on aeri...
