Utah State University Extension has a nice publication summarizing the forage value of a number of noxious weeds and a summary of toxicity reports of many of the plants at the end. The report was written by Beth Burritt and Rae Ann Hart and published in May, 2014. There’s a lot of research that still needs to be done on these plants, but it could be a good first guideline if you are interested in using grazing animals to control invasive plants.
