Interesting thought, Will...I hadn't looked too closely at some of the trees in the way back. The one looked like a red pine to me, but I can't really tell what the other one is... I got this picture from a print that my parents had hanging in their house (and now hanging in my house) that they purc...

I have visited Cathedral Pines for years--I think state law required foresters from Wisconsin to visit this stand of timber!! And Lambeau Field, too! The few remaining stands of old white pine helped me get interested in forestry as a career... <<NOTE: IT WAS POINTED OUT TO ME THAT THIS PICTURE WAS ...

Hello, Roy...I, too, am a displaced Yankee living in the South (grew up in northern Wisconsin, BS & MS in Forestry at Michigan Tech), now a Research Forester with the US Forest Service, Southern Research Station in Monticello, Arkansas. We get back to the Wisconsin/Michigan area frequently, and actu...

Bob-- I'm not sure what it will take to influence how my agency measures tree heights--some of it is of course worked into the equipment-related expenses, and I'm sure many would argue for the need to maintain "continuity" in how measurements are applied...of course, we know these are just lame excu...

Chris--thanks for noticing that glitch...it will be fixed by the next issue.

Bob-- Could you write something up on this particular exercise for the Bulletin of the ENTS? I have long wanted to do this kind of a test for traditionally trained foresters and ecologists, and then compare the results in a rigorous, statistical manner to (hopefully) prove to them that the sine meth...
