FIA-COLE Workbook for White Pine

Hi Ents, I keep working on the FIA-COLE volume-biomass calculators. The attached Excel workbook is getting there for eastern white pine. It contains a shortcut formula that comes within about 1% of what the workbook gives. You can use the formula in the field. But to use the workbook to calculate ab...

Re: New Reticle Formulas

Micheal,

Thanks for the feedback. It is gratifying to know that our reticle-based measuring can be applied to the California behemoths.

Re: Greenwich, CT Sites

Ryan, A worthy project for us could be to tell the story of the species in New England. So far, I have a single tulip over 140 in Massachusetts, but there probably quite a few over 130. We have two on our property just a few years from where I'm sitting. Regardless, the species would make a good sto...

Re: Modeling the Pinchot

Ryan,

No, I haven't. Do you have an image of it? Is it in a location that allows it to be easily measured?

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.

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.
