Decadal Reevaluation Of Sugar Maple Dieback Etiology Across The Upper Great Lakes Region, Mattison E. Brady

Dissertations, Master's Theses and Master's Reports

Sugar maple (Acer saccharum) is a foundational tree species in northern hardwood forests of the United States and Canada. Though previous work has documented areas of substantial stress for this species in eastern North America, increasing reports of crown dieback in the Upper Great Lake states through the early 2000’s highlighted the relative lack of understanding of regional trends and causes. A 120-plot network of maple forest health monitoring sites was established and annually visited across Upper Michigan, northern Wisconsin, and eastern Minnesota between 2009 and 2012 to catalog and understand the regional phenomenon.

Development Of A Propagation Program For Beech Bark Disease-Resistant American Beech (Fagus Grandifolia) And An Applied Restoration Plan For Mitigation Of Beech Bark Disease, Ande Myers

Dissertations, Master's Theses and Master's Reports

This dissertation describes the work accomplished towards mitigation of beech bark disease (BBD) through a joint venture by Michigan Technological University and the National Park Service. American beech is an ecologically important species that is threatened throughout its range by beech bark disease and other newer, emergent pressures such as climate change and beech leaf disease. A literature review is included to synthesize recent advances in American beech (Fagus grandifolia Ehrh.) propagation and their application in mitigation of BBD (Chapter 2). These concepts are examined in an applied restoration framework to outline the importance of understanding ecological and technological …
