1. Aubihl, Elijah. Density-Dependent Survival of White Ash (<i>Fraxinus americana</i>) at the Allegheny National Forest.

Degree: MSin Botany, Biology, 2019, Miami University

The study of the rapid decline of ash trees caused by the emerald ash borer beetle (EAB) has been well documented, but little is known about the decline of ash stands when a subset of trees is treated with insecticide. The treatment of a subset of ash trees in areas may provide protection to those ash trees that are untreated, resulting in the associational protection of untreated ash trees provided by treated ash trees. Two objectives of this study were to test whether such associational protection can occur, and the threshold, if any, at which associational protection occurs. The third objective was to test whether any ensuing mortality depended on the density of ash trees. This study was conducted in the Allegheny National Forest, located in Northwestern Pennsylvania and is part of a larger study by the U.S. Forest Service focused on preserving the genetic diversity of ash trees in the Allegheny National Forest. My analyses indicate no protection from insecticide and no associational protection. Further, I found that low ash density forest stands display faster rates of decline caused by EAB than high ash density forest stands. These findings are from the analyses of datasets from the first two years of a ten-year study and although they are from the early stages of a long-term study, the management implications are valuable. Advisors/Committee Members: Stevens, Martin (Advisor).
