Progress 08/01/09 to 09/30/12
Outputs
Progress Report Objectives (from AD-416): Develop research-based recommendations to increase the ability of the USDA-NRCS to assess the effects of conservation practices, in particular through the enhancement of NRI data collection, analysis and interpretation. Approach (from AD-416): The project includes three elements, each with a unique approach. Recommendations for the enhancement of NRI data collection and analysis will be generated through the integration of field-based measurements, improved techniques for processing and interpretation of high resolution aerial photography, and the development of new remote sensing analysis approaches. Recommendations for the enhancement of existing NRI sampling will also be generated through a sensitivity analysis of the existing approach, and review of possible alternatives that account for variability associated with ecological sites. Finally, a new wind erosion model will be calibrated with field data and applied to existing NRI data. This project is an extension of 6235-11210-006-91R. This progress report addresses progress for the extended project. In 2011, we published results of analyses of a new approach to interpretation of high- resolution imagery for the National Resources Inventory. A separate publication addressing statistical requirements for national surveys was accepted by another peer-reviewed journal. These results will be used to support improvements in the quality and cost-effectiveness of data collection for national inventories of land condition. We also made significant improvements in the rangeland Wind Erosion Model (WEMO) and hosted a workshop designed to address differences between WEMO and the cropland model, Wind Erosion Prediction System (WEPS). E-mail and telephone communications occurred throughout 2012 with On-site meeting occurring in Washington, DC and Cloudcroft, NM. This serves as a final report.

This progress report addresses progress for the extended project. In 2011, we completed analyses of a new approach to interpretation of high-resolution imagery for the National Resources Inventory. We also evaluated the potential application of unmanned aerial systems to eventually provide this imagery. These results were reported in peer-reviewed journals. A separate publication addressing statistical requirements for national surveys was submitted to another peer-reviewed journal. These results will be used to support improvements in the quality and cost-effectiveness of data collection for national inventories of land condition. E-mail and telephone communications occurred throughout 2011, with an on- site meeting occurring in California and Washington, DC.

This progress report addresses progress for the extended project. In 2010, we initiated a new project to increase the sensitivity of the National Resources Inventory (NRI) to conservation effects at finer scales through the NRI sampling design.
