説明 | The rampant application of herbicides in the riparian setting, presumably to control Tanacetum vulgare, kills many native plants and threatens a locally rare population of orchid, Cypripedium calceolus (Cypripedium parviflorum). Green ash, a tree native in eastern Montana, is perhaps one of the more common exotics in this riparian area. |
