Abstract

American elm (Ulmus Americana L.) was a dominant species in floodplains and swamps of the Midwest before Dutch elm disease (DED) (Ophiostoma ulmi and O.novo-ulmi) reduced its populations. In many areas, ash (Fraxinus spp.) became dominant in these ecosystems. Emerald ash borer (EAB) (Agrilus planipennis), an introduced insect, is now spreading through the Midwest and killing up to 99 percent of ash trees in infested areas. In spring 2011, we began a restoration experiment to study reforestation of ash-dominated floodplains impacted by EAB through plantings of native tree species, including DED-tolerant American elm, sycamore (Platanus occidentalis L.), and pin oak (Quercus palustris Münchh.). We are testing the effect of planting trees before, during, or after ash mortality by planting in sites across a gradient of EAB infestation duration. Initial causes of seedling damage differed among sites. At sites that experienced flooding, many seedlings had wilted leaves. However, at the site that did not experience flooding, most seedlings had insect herbivory. Initial seedling mortality was low and differed among sites and species. American elm seedlings tolerant to DED performed as well as or better than the pin oak and sycamore seedlings planted in this experiment. Future results of this experiment will provide recommendations to managers for methods to restore EAB-impacted floodplain forests with DED-tolerant American elm and other tree species.
