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 A literature search has been conducted and contacts have been made with several landowners who have good records of past management practices on grazing allotments. In one instance stocking rate and rotation records are complete back to 1980. Currently we are evaluating the availability and spatial resolution of remotely sensed data.
