Research Project: Conservation Effects Assessment Project - Grazinglands (BURNS 2011)

Location: Range and Meadow Forage Management Research

2012 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 will be extended another year and progress this year was made on Objective 1 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 and management records have been collected for several public land grazing allotments in eastern California and eastern Oregon. The historical trends at the eastern Oregon site correspond closely to remotely sensed values of normalized difference vegetation index (NDVI). A manuscript on the eastern Oregon research is currently in peer review.
