Distribution And Growth Of Autumn Olive In A Managed Landscape, Matthew Ruddick Moore May 2013

Distribution And Growth Of Autumn Olive In A Managed Landscape, Matthew Ruddick Moore

Masters Theses

Invasions by exotic plant species result in significant challenges for forest managers. Disturbance and increased light have been shown to facilitate the successful establishment and invasion of exotic, invasive plant species. Several studies have sought to determine which key factors lead to greater abundance of exotic, invasive plants on certain sites and this information is important for determining the likelihood for exotic plant invasions at broad scales. Site characteristics that may promote autumn olive (Elaeagnus umbellata) were studied. Our goal was to identify variables associated with forest road edges most important in explaining autumn olive abundance and growth. …


Steps Toward Butternut (Juglans Cinerea L.) Restoration, Sunshine L. Brosi Aug 2010

Steps Toward Butternut (Juglans Cinerea L.) Restoration, Sunshine L. Brosi

Doctoral Dissertations

Butternut (Juglans cinerea L.), a lesser-known relative of black walnut (Juglans nigra L.), is a native tree species beneficial for wildlife, valuable for timber, and part of the great diversity of species in the eastern forests of North America. Populations of butternut are being devastated by butternut canker disease, caused by the fungus Sirococcus clavigignenti-juglandacearum (V.M.G. Nair, Kostichka, & Kuntz), which is thought to be introduced to North America. The disease causes multiple branch and stem cankers that eventually girdle trees. Small population sizes, lack of sprouting, and shade intolerance exacerbates the disease and results in permanent losses of butternut …
