摘要：

Purple loosestrife (Lythrum salicaria) is a nuisance exotic species that displaces native plants and has little value as food or habitat for wildlife. Attempts to control adult plants have had limited success. We investigated the effects of shallow flooding (< 30 cm) on the growth and survival of purple loosestrife seedlings. Pots containing purple loosestrife seedlings were assigned to each of 12 treatment combinations: 3 seedling height categories and 4 flooding depths. Mean stem densities were not affected by the treatments (P > 0.05). The flooding treatments significantly affected mean stem heights, but there were no identifiable trends within size classifications. All seedlings continued to grow during the experiment. The survival of any purple loosestrife plants can have serious implications in wetlands. The results from this study indicate that shallow flooding is not an effective approach to limiting or preventing establishment of purple loosestrife seedlings.
