Forest Herbicides



My research broadly addresses the pattern and dynamics of forests and how to apply this knowledge to inform management. Some of the main areas of research under this theme include:

·         The ecological impacts of disturbances, both natural and human-caused, on forests with an emphasis on forest regeneration and stand dynamics under active forest management.


·         Addressing emerging impact factors, such as climate change and biological invasion, on forests and using this to inform adoption of silvicultural approaches for mitigating these impacts.


·         Research on the efficacy of management practices for meeting diverse non-timber objectives, including research that addresses the consequences of wildlife habitat management on forest vegetation and how to modify these practices to also meet silvicultural objectives.


·         The application of silviculture where the restoration of historic natural communities is a primary objective.



I am currently working on several projects. These include:

·         The effects of alternative forest management systems on the adaptability of Ozark forests to projected climate change.

·         Silvicultural options for improving the quality and composition of upland and bottomland hardwood stands.


·         Stump sprouting of Midwestern bottomland hardwood species.

·         Methods for reducing dense understory layers on mesic sites.
