Research Project: Conservation Effects Assessment Project - Grazinglands (BURNS 2011)
2013 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 was extended in FY2012 for another year but disapproved and closed in FY2013. There is no progress to report for FY2013 and this is the final report. In FY2011, a literature search was conducted and contacts were made with several landowners who have good records of past management practices on grazing allotments. The availability and spatial resolution of remotely sensed data was evaluated. The progress in FY2012 was made on Objective 1 of the parent project which relates to the effects of fire, mechanical treatments, livestock grazing, introduced invasive weeds, western juniper expansion, and climate on the vegetation and watershed function of sagebrush steppe rangelands. Historical vegetation data an dmanagements records were collected for several public land grazing allotments in eastern California and eastern Oregon. The historical trends at the eastern Oregon site corresponded closely to the remotely sensed values of the normalized difference vegetation index (NDVI). A manuscript "Remote sensing and grazing management: A case study on an Oregon Creek" has been submitted for publication.
