Current Research

How forests are managed and what purposes/uses they are managed for can inadvertently result in conditions more conducive to the development of damaging diseases than under previous management systems. Many forests in the Midwest are undergoing natural successional changes as well as silvicultural changes that influence populations of pathogens. We are researching these interactions and developing new management guides to minimize the incidence and severity of disease. Exotic pathogens causing white pine blister rust and butternut canker continue to have serious impacts on their hosts, and we are working to develop management, conservation, and restoration guides to manage these ecologically important forest tree species

Research Interests

We are beginning to use GIS tools in developing and studying local and regional models to explain and minimize disease outbreaks in native forest ecosystems and plantations.

We have limited knowledge on the distribution of many endemic fungal species and a poor understanding of their ecological role and importance in forest systems. These organisms and their interactions with other biotic organisms and abiotic factors need to be studied either to maintain their functions or prevent their undesirable effects.

Why This Research is Important

Native fungi and diseases are natural components of healthy forests that have many beneficial roles, however, under certain conditions periodic disease outbreaks can interfere with management objectives. Exotic pathogens have had profound effects on forest ecosystems and methods for the conservation and restoration of tree species impacted are needed.
