I've got a bunch of stuff, incl. that summary. Just PM me with your e-mail, or PM me and I can give you my e-mail, I'll send them your way. Do you read French? A lot of the literature I peruse is in French. My summary is a .doc, the others are all PDFs.
Keep in mind when you look at my summary, is that these are all species actually observed eaten - any flora that were not favored by the cows in the lower pastures and higher Abondance alpages were excluded from the studies.
I mentioned to you, I'm extremely traditionalist in so many ways. I'm also a purist, to a fault with no false plea begging meant - it really is a fault. It's not easy for me to compromise a vision, once conceived. Unfortunately I may be forced to do just that, if I and my family remain here in the States. I'm interested in doing some Rocky Mountain studies, as a start.
It's also interesting to note - I believe it was in Voisin's Grass Productivity - that there are some studies discussing palatability of the same species at different altitudes. The one that comes to mind mentions that the lower elevations tended to produce a woodier version at the same stage of apparent growth. Which I find really interesting in terms of some of these more "bizarre" or surprising plants consumed.
