Re: Terrestrial LIDAR

Here are three photos of the Leica BLK360 lidar instrument operating during a scan. In the slot that's visible in the head of the unit (photo 1), there's a small mirror that rotates at high speed, scattering millions of laser pulses outward. In photo 2, the mirror in the slot is a blur, since it's r...

Re: Woods Hole Research Center

I think the thickness of a ring might be a bit more complicated an issue than just a simple inverted cone with a continuous taper in its thickness. Growth is greatest just below the crown, where the downward flow of photosynthates is greatest. So, from the ground up to just below the crown, the ring...

Re: Woods Hole Research Center

Brother Bob, does your comparison/calculation of ring widths between smaller/younger trees and taller/older trees take into consideration that the thickness of a ring varies from top to bottom of the trunk? Most growth occurs just below the crown, creating a taper in the ring thickness from top to b...

Re: Colorado workshop

Hmmmm, it's been a loooong time since I've shinnied up a tree, and I'll go out on a limb here (tee hee) and guess Bob's a bit out of practice too. But who knows... if there's ice cream waiting up there....

Re: New Tom Wessels film: "Reading the Forested Landscape"

Joshua, Most of what Tom brings to light is common sense, isn't it? But how many of us have taken the time to think about such things and do the kind of detective work he does? Learning to apply these lessons does take time and practice, but doesn't it make time spent in the woods that much more int...

Re: White Tailed Deer Damage to Northeastern Forests

Don, I was deeply involved in the issue of opening Quabbin for hunting to reduce deer numbers. Their numbers were indeed high, and foresters could get virtually no tree regeneration at all. However, we felt that the continuing and constant cutting that had been going on there was certainly exacerbat...
