Plains cottonwood and peachleaf willow seedling establishment was studied to determine the effects of seedbed disturbance and irrigation along Boulder Creek, Colorado (40° 3' N, 105° 8' W). The study reach of the stream had mature cottonwoods and willows in the riparian area. In May 1992, two meter wide strips that stretched from the water’s edge to the natural edge of the floodplain were divided into sections, 19 to 30 m long, based on treatments. These strips were divided into three plots that were then were divided into eight subplots with treatments and combinations of treatments (irrigation and no irrigation, sod removal and no sod removal, and seed addition and no seed addition). Natural seedfall occurred on all plots. In September of 1992 and 1993, woody species density was measured.
