DescriptionThe black cottonwood riparian forest is an important component of the otherwise xeric landscapes of the Intermountain West of North America. Regulation of rivers by dams has attenuated peak flood flow events, quickened the rate of decline in river stage after the peak event, and hindered the delivery of maintenance flows throughout the remainder of the growing season. As a result, sexual reproduction of trees has been diminished causing the population to be largely a result of vegetative growth from roots and runners. Field studies, examination of historic hydrology data, and large-scale in-situ experiments along the Boise River in Southwest Idaho provide the evidence to conclude this population too has been adversely affected by a change in the hydrology of the river, but remains capable of reproducing from seed if the surface of the floodplain is artificially disturbed to prepare a proper seedbed. Further, it shows the intentional manipulation of the source of soils can produce differing communities of understory shrubs, grasses, and forbs with some more desirable than others. With this information restoration ecologists can now better prescribe the means and methods to grow a native array of plants that complement adjacent landscapes, resist invasion by exotic species, and offer the greatest probability of survival and growth of individual plants.
