Description

Abstract Text:
Forest management for multiple uses including timber production, carbon sequestration, ecological conservation, downstream water quality and quantity, and recreation all require landscape level understanding of the drivers of hydrological and ecological processes including carbon stocks and transformations in soil, water and air. In keeping with the mission of the USDA Forest Service, this project addresses the long-term goal of understanding how the intersection of nutrients, water, energy, vegetation, and microbial dynamics at small spatial scales leads to heterogeneity and system level behavior at the landscape scale. Understanding primary influences on soil C transformation across space and time and differential landscape responses to climate variability and disturbance are requisite for informed management and mitigation of perturbation in areas of complex topography, vastly under represented in ecosystem and carbon cycle science. Our research helps fulfill this charge by providing knowledge for informed forest management decisions. For example, increasing forest productivity while balancing climate sensitivity, greenhouse gas emissions, and carbon sequestration is a pressing need for managed landscapes. Current mitigation for greenhouse gas emissions calls for increased soil C storage, yet our understanding of the effects of forest harvesting on soil C transformations and storage remains limited. Current U.S. Forest Service efforts at the site include management treatments (e.g., forest thinning vs. harvesting) to lodgepole pine stands over the last 10 years. Our project will take advantage of these experiments to examine soil C transformation across sites with different management treatments, in addition to sites with different landscape morphology and environmental gradients. This study will provide valuable, supplemental information on soil and forest productivity that can inform best forest practices and provide a framework that can be extended to other biogeochemical cycles in soils and to diverse landscapes with significant benefit for managing and predicting ecosystem responses to perturbation and climate change.

It is important to recognize, and consider in any interpretation of Federal RePORTER data, that the publication and patent information cannot be associated with any particular year of a research project. The lag between research being conducted and the availability of its results in a publication or patent award varies substantially. For that reason, it's difficult, if not impossible, to associate a publication or patent with any specific year of the project. Likewise, it is not possible to associate a publication or patent with any particular supplement to a research project or a particular subproject of a multi-project grant.
