2019-09-06: Our discovery of this thistle species, now thought to be Carduus cenereuscinereus, was not as early an early a detection as one would like.  It also took us all a while to recognize it as something different from Italian thistle (Carduus pycnocephalus) after that.  The plant has limited windows of visibility and exists in some of the most rugged and remote country we have in Oregon. It is super rough country to access. This site is almost a 20 mile ride into back country, or a 3 hour drive plus an hour jet boat ride plus a 5-mile hike. It is much easier to have horses and mules carry you and your gear in to treat these sites. Add in complex NEPA considerations over time, low weed control budgets locally, and there is much left to do.
