Who would volunteer to save the hemlocks?

Pressurized trunk injections would be ideal, but we'd need trained arborists, not volunteers then.

Better check the financial disclosures on that citation of yours lol

Few if any long-term ecological field studies of actual Imidacloprid use in the real world exist, though there are many laboratory studies easily identifiable using Google scholar:

It seems like the setting of use is critical with this chemical. The stuff is toxic enough and features a long enough half-life (in addition to being banned across most of Europe: http://www.efsa.europa.eu/en/efsajournal/doc/3066.pdf) to think twice about its widespread use here. As usual, US regulation lags far behind the rest of the developed world and most of the "safety" studies were funded by the pesticide industry... so no easy answer on this one just yet.

Is this the only chemical found to be effective for the hemlock treatment?

Seems to be the only affordable one back in our neck of the woods. Unfortunately it was used too late or not at all and most of our trees our dead.

I have to say its awesome seeing so many folks concerned about ecology and conservation. That being said let the RRGCC know how we can help1 (we have an army of 5 gallon buckets)! We will be more than happy to assist in anyway possible. A few things we would like to request, we would like to know which trees, locations (gps would be great, maybe a unobtrusive way to mark the trees?) and a method of treatment. This is all so we might begin a database of treatment so we don't retreat the same trees and can monitor them as time progresses. We would also like to know a plan of attack before it happens (just so we are aware of what's going on and when). Otherwise we can stay out of it and let y'all run with it.

Again THANK YOU ALL!! All BS aside we do have one of the best climbing community's around.

Shannon we appreciate all you have given and all you continue to give! Thanks for taking this up!

Yes we do know what is causing colony collapse. pesticides and herbacides. all of them

What do you mean "most of our trees our dead"? If I didn't know any better I would say this is in reference to Muir Valley? But that would mean that potts is....weber?? Whoa.

[Artsay]

Shannon, I work at UK and they successfully treated their hemlock trees maybe about three years back now (at least I think it was successful?). I can speak with our Grounds department if you want and ask any questions you need if you think that would be helpful.

Strange that you and "Kev Potts" aren't Facebook friends. For an internet savvy guy you'd think you guys would be buds on FB.

This is great! Now, the only question is... When will our buddy Rick close Muir Valley! He is starting to look a little crazy on here... Well unless he keeps deleting and changing his post...
