Abstract Details

2018, Master of Science in Botany, Miami University, Biology.
In the fragmented forests of Ohio, native tree recruitment has been reduced by abundant white-tailed deer and invasion of Amur honeysuckle (Lonicera maackii). While shrubs compete with tree seedlings, live shrubs can facilitate growth and survival of native tree seedlings in the presence of deer. It is less clear if dead shrubs can have this same effect. In this study, I tested the hypothesis that dead L. maackii shrubs provide refuge for native tree seedlings from deer browse and facilitate growth and survival. In the Miami University Natural Areas in Oxford, OH, I planted 512 native tree seedlings within plots comparing controls to three different L. maackii removal strategies: complete shrub removal, felling of shrubs leaving branches on the ground, and basal bark herbicide application. I found that dead branches in the Felling treatment provided refuge from browse and facilitated growth and survival for Carpinus caroliniana, but did not facilitate growth and survival for Quercus alba, Celtis occidentalis, or naturally occurring seedlings. This result partially supports the hypothesis that dead L. maackii branches facilitate growth and survival of native tree species, but demonstrates that the effect varies among tree species and may be dependent on deer browse preference.
