2011 Annual Report 1a.Objectives (from AD-416) To provide quantitative information and analytical tools that can be used to evaluate the impact of selected grazingland conservation practices on natural resource values. 1b.Approach (from AD-416) This objective will be achieved by improving inventory and monitoring techniques and conducting field measurements of the impacts of brush control, prescribe burning, vegetative seeding, grazing systems, and other conservation practices on soil and water quality including the movement of nutrients and particulate matter and significant changes in biodiversity. 3.Progress Report This project is an extension of 6235-11210-006-91R. 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 correspondence and telephone communication occurred, scheduling on-site meetings with NRCS.
