"Pacific ninebark provides good cover and nesting sites for birds and small mammals but has low palatability when browsed by deer, elk and bear." [1]
"It has ornamental value for the wild garden or open woodland. Although considered toxic by some, Pacific ninebark was used as an emetic, purgative and laxative by Native Americans." [1]
"Pacific ninebark’s fibrous roots and capacity to root from un-rooted cuttings make it suitable for soil bioengineering techniques including live stakes, fascines and brush mats. It is particularly valuable for streambank and lakeshore stabilization applications." [1]
