| 説明 | Sulphur cinquefoil remains common at the north end of Burke Park after decades of attempts to eradicate it with herbicide. The main effect of herbicide has been to decrease native plant diversity and promote exotic perennial grass abundance, mainly of smooth brome (Bromus inermis) and quackgrass (Agropyron repens). This site lies adjacent to the cemetary, Burke Park, Bozeman, Montana. |
