[NAFEX] Killing Poison Ivy Organically/elevation

WI p.ivy doesn't mind cold winters, not much bothered by dry soil either.  I 
don't recall seeing it on the driest sand, nor in marshes, otherwise "it's 
everywhere".  Could elevation really be the limiting factor?  Seeds are 
moved by birds; are they very strict about elevation?

I think you're right about the temperature.  There's a fairly sharp line in 
NH and upstate NY between where the poison ivy grows, and where it doesn't.  
I'm pretty sure it corresponds to winter low temps.  At any rate, I know 
several places where it grows next to the water, or in the valley, but 
doesn't grow once you get a little elevation.
