Research Interests

Despite co-occurrence of a multitude of fungal pathogens with susceptible tree species, most forests remain generally "healthy" and productive most of the time. However, this dynamic balance periodically is upset, and disease epidemics occur in both natural forests and among planted trees. We are particularly interested in how changes in tree condition (induced by climate, competition, insect pests, or forest management practices) and diversity within populations of fungal pathogens influence the incidence and severity of diseases of trees.

Much of our recent effort involves investigations of fungi such as Diplodia and Sirococcus species, causal agents of shoot blights, and their interactions with various conifer host trees. Studies include: (1) molecular genetic comparisons among isolates of these pathogens and related fungi; (2) greenhouse evaluations of the host range and aggressiveness of distinct populations of these fungi; and (3) forest and controlled environment studies of host moisture, nutrition, and geographic seed source effects on disease development.

We also maintain the interest and flexbility to respond to changes in the health of Wisconsin's forests that result from new or increasingly important tree disease problems. Among these are root rot of conifers caused by Heterobasidion irregulare and diseases caused by fungi in intensively-managed poplar plantations.

Members of our group work closely with state, federal, and private pest specialists and foresters. Together, we integrate previously-existing knowledge and recent research results into current practices and future plans for maintaining the environmental, social, and economic benefits derived from healthy trees and forests.
