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.
