Re: Cathedral Pines, Cornwall

Jared, We are indebted to you and Ray for bringing the Cathedral Pines back up on our tall tree radar. This once New England flagship stand was a favorite haunt of mine and of my son Rob. JACK SOBON measured a pine there in the 1980s to 172 feet using his transit. There were a number over 160 accord...

Re: Rucker Comparisons

Brian, The epicenter of black birch development is presumably a strip going across southern New England and NY and PA. Ohio has its share also. When white pine and oak are cut up here, black birch springs up in profusion. Some years ago, I started a black birch database as you'll likely recall. In t...

Re: Rucker Comparisons

Brian, The birch at Smith College is a black birch. In terms of its white cousins, John Eichholz broke 100 feet on a white birch in Mohawk Trail State Forest years ago. I can ask him what his numbers are. Interestingly, of yellow, black, and white. black is the clear height winner in New England, an...

Brian,

Jared Lockwood and I measured a quaking aspen to 108.0 feet on a private property in Stockbridge, MA. It was in 2017. Best I issn do now.

Re: LTI TruPoint 300

Ents, Steve Colburn recently informed Cadre members that LTI has secondhand TruPoint 300 units available for $875/unit. New ones now cost $1,300. The used price is truly a good value if you can make use of the versatility of the instrument. But what might that mean for tree-measurers? The 300 is adv...

Re: Rucker Comparisons

Brian, Great job! BTW, not that it matters, but John Eichholz and I share the credit for the bigtooth aspen in MTSF. It was my original discovery and was once 126.5 feet tall. Subsequently, its crown began to die back. Wh en John got to it, it was down to 126, and continued dropping from there. Bob

Re: LTI TruPoint 300

Ents,

The testing of the TruPoint 300 Diameter function continues. My 300, which I affectionately have named YODA is performing extremely well.
The attachment tells the story.

Re: LTI TruPoint 300

ENTS, Of late, I've resumed testing the TruPoint 300 as I promised LTI I would do. The attachment shows the TruPoint's accuracy for trunk diameter measurements as of 10 trials. As the number of trials expands, I don't expect the average difference between caliper and TruPoint measurements to stay so...

Re: New mission?

Erik, Thanks for a most thoughtful and insightful response. I'm am glad that you see a continuing role fro NTS in areas where we can practice our trade. We function in an arena filled with heavyweights, but whose collective work reflect highly conflicting results. When one digs into the scholarly pa...

Re: New mission?

Ents, Well, I haven't exactly been swamped with comments about a carbon mission. Perhaps it is too much of a stretch for NTS, and again maybe not. I would like to hear the thoughts of others on what you think is important to pursue now and into the future. Thanks in advance to anyone willing to shar...
