Re: Walker Cove Big Ivy/Coleman Boundary NC

Brian, From the early 1990s when I first visited Walker Cove, you've put the watershed on the map. It is great to see what this exceptional watershed grows. I was surprised at the 166-foot white pine. Again, white pine and tulip trees duke it out for first place, but there are soooo many more tall t...

Re: Mountains-to-Sea Trail

Brian,

Pretty impressive. Are the Arboretum managers aware of your measurements? So far, I've seen no evidence that most arboretum personnel have mastered height measurement, so we have a mission to bring them up to date.

Re: Far Mill River, Stratford, CT

Ryan,

Again, congratulations! CT's tulips are recapturing some of the state's lost glory when the Cathedral Pines blew down.

Re: Greenwich, CT Sites

Ryan,

You are single-handedly putting Connecticut on the map. What we are seeing is the maturing of tuliptree across the landscape. Connecticut is the only New England state with a capability for 160-foot tulips.

Re: Modeling the Pinchot

Ryan,

I expect around 2,300 or 2,400 cubes. Armed with a toolkit of new reticle formulas, hopefully, Jared and I can do a thorough job later this year.

New Reticle Formulas

Ents,

Michael Taylor, Jared Lockwood, Erik Danielsen, Elijah Whitcomb, etc. and I continue perfecting reticle-based tree measuring. The attached Excel workbook adds some tools/methods to the repertoire. They need testing, but do extend our capability to deal with leaning and tapering trunks.

Re: NE forests were old growth not cultured.

Lucas, No surprise to me in what David said in the article. Through their decades-long pollen grain research, Harvard Forest has progressively moved away from the belief that Native Americans routinely torched the landscape with reckless abandon for millennia - at least here in the Northeast. The na...

Saheda Carbon Report

Ents, Please see the attached report on Saheda. It analyzes the performance of this huge pine in terms of its volume growth and carbon sequestration relative to itself at earlier ages and to a cluster of younger pines occupying a space equivalent to its projected crown area. The report is admittedly...

Re: Comparison FIA Vol Model to NTS

Hi All,

The attached Excel workbook is up to date and provides a 3-way comparison between FIA-COLE, reticle, and form factor measurements of the trunk volume of a stand-grown white pine.
