It is native to parts of the Rocky Mountain states, and is also unpalatable to livestock. Areas where it occurs in abundance also indicates over-grazing. <BR/> See: http://en.wikipedia.org/wiki/OvergrazingAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-29504535.post-35229273784463007862008-07-25T14:32:00.000-07:002008-07-25T14:32:00.000-07:00Thanks for the clarification.

So, overgraze the land, thus suppressing all the nice nutritious grass and forbs, well of course the iris moves in once competition is removed. <BR/><BR/>Seems to me that the noxious weed categories are quite suspect. Who got iris douglasiana listed in the first place? Cattle ranchers who wanted to apply herbicide on BLM land? -- just a wild guess.<BR/><BR/>MarkAnonymousnoreply@blogger.com
