The woody phreatophyte communities of the Republican River Valley were studied by means of 33 transects located at 4-8 mile intervals along the 285 miles of its course in Nebraska. Two principal types of communities are present and are located, respectively, on the west and east halves of the valley: (a) those in which cottonwood and peachleaf willow are the sole dominants and (b) those in which cottonwood and peachleaf willow have high importance values but in which there is a well-developed understory of mixed hardwood species. Thirteen species of trees were found in the transects and three others were seen in stands along the river. (Author)
