Consistent with the terrestrialization hypothesis, short-duration floods provide a practical method for controlling exotic annual plants where river regulation has reduced the frequency of natural floods. As exotic impacts are greatest in dry periods, when exotics are most abundant, ecosystem benefits will be greatest when flooding leads to a protracted decline in exotic annuals during the dry (non-inundated) years following flood recession. Otherwise, reductions in exotic annuals may be transient and have little positive impact on floodplain ecosystems and processes.
