Acer negundo/Prunus virginiana (box elder/common chokecherry) Habitat Type

The presence of Acer negundo (box elder) is key to the successional direction of the stand which is still dominated by Populus deltoides (Great Plains cottonwood). Notice the beaver work on the large cottonwood. This site is along the Upper Missouri National Wild and Scenic River northeast of Fort Benton, Montana (elevation is approximately 879 m; 2,900 ft).
