Gaines- Reflecting my lifelong appreciation of what came to be called old-growth, the thoughts I had paging down through your comments and images, had me thinking of the way I "define old-growth". 1) Vertical stand structure is heterogeneous (reflects diversity of ages and types) 2) Horizontal heter...

Does anybody else see a similarity between Apple's new Face ID security measure with it's 3D identification of facial features, and the technique that Michael Taylor uses when using digital imagery to create a 3D image of a tree's bole? I'm thinking that there might be developers soon working on app...

Erik- Reasonable questions all. Plus, if my understanding of how image stabilization works, it's the "averaging of pixels with the least difference over all" which suggests that there is some accuracy lost in the averaging process...bound to be thoroughly statistical, and subject to confidence level...

For much of the last several decades, it seemed like the phrase or descriptor "old-growth" had fallen out of favor. So I was interested to see the Barton/Keeton release of the Ecology and Recovery of Eastern Old Growth Forests. Having delved into this topic in the 1990s, I had a sense of what it was...

Lucas...even if it didn't start off with "It was a dark and stormy night...", to pre warn you?! I had similar reticence at the first, but stayed with it...in retrospect, I wonder how he managed to make it as cohesive as it was...

Bob-
Off the top of my head, I recall from one of the Sillet/VanPelt papers that at times annual rings will not be continuous around the complete circumference...I don't recall that the annual rings failed to regain continuity above or below the 'disappearing annual ring'.
