Interesting case, sounds like all involved have been doing some great forensic/research work.
However I find it odd that the elk were ingesting the lichen in the first place considering that it is in the soil. Perhaps a long dry winter was driving them to eat stuff they normally don't in high quantities.
It is good to know it is something common causing the issue. Speculation was running wild that it was human poisoning, some new form of cwd, a new diesease, alien abuduction, etc.... I had even read people theorizing that the elk in true lemming style had just "run themselves to death".
Here is the scenario... you sit in your 2 piece climbing stand and your foot inadvertently bumps the lower section while there is no weight on it - and it slides down the tree, out of reach!
OK, you are safe - you have a string tied from the upper section that you are sitting on and the foot portion that slid 4-5 feet down the tree. All you have to do it pull the other section up, reposition it and you are back in business, correct?
Have you ever tested this theory?
I have -...
