Research Interests
- Using prescribed fire to achieve stand- and landscape-level goals and objectives

- Integrating elements of natural disturbances into traditional silvicultural treatments to increase ecological complexity
- The effects of disturbance, both anthropogenic and natural, on attributes of ecological complexity
Why This Research is Important
The forest systems of the southern Appalachian Highlands are diverse in their ecology, and their ability to provide the resources and services demanded by society including water, timber and biomass, recreation, wildlife habitat, aesthetics, and landscape diversity. Minor changes in topography greatly affect site productivity, species composition, competitive interactions, and response to disturbance. Our limited understanding of forest dynamics and ecological processes throughout stand development and across this complex landscape greatly inhibits land managers' ability to predict the response of vegetation to both planned silvicultural treatments and unplanned natural disturbance events. There is a need to improve our knowledge of the establishment and sustainability of forested systems under the influence of natural and silvicultural disturbances as well as under varying climatic scenarios. Silviculture is used by resource managers and forest planners to balance multiple-use with sustainability. Our efforts to predict and manage the dynamics of southern Appalachian forests under disturbances is directly tied to our ability to understand the differential responses of southern Appalachian tree species to both natural and anthropogenic (i.e., silvicultural) disturbances, including climate change. Quantification of the response to disturbance across environmental gradients will better enable natural resource practitioner to better predict changes in forest structure, composition, and habitat quality and to develop methods to meet management and restoration goals.

Research Highlights
- Scientists Embrace Shared Stewardship to Deliver Silviculture Research (2020)
-
Since 1992, the SRS Upland Hardwood Ecology and Management Research Work Unit has provided workshops and trainings to fulfill continuing education requirements for both federal and non-federal land managers. In 2020, scientists planned to introduce an updated Upland Hardwood Silviculture course to meet training needs of state partners in the southern region.
However, the COVID-19 pandemic forced scientists to quickly modify the logistics and structure of this highly anticipated training. With assistance from SRS IT specialists, SRS scientists conducted an all-virtual short course. The course delivered the most up-to-date information about the management of upland hardwood forests to more than 100 foresters and natural resource practitioners.
