Research Insights in Semiarid Ecosystems (RISE) Symposium
The fifth annual Research Insights in Semiarid Ecosystems (RISE) Symposium will feature invited speakers presenting recent research on the USDA-ARS Walnut Gulch Experimental Watershed, University of Arizona Santa Rita Experimental Range and other outdoor laboratories. There will also be a poster session where students and researchers are encouraged to report on completed or in-progress studies. Time will be available for questions from the audience.

Prior to starting my current position with the U of A at the V Bar V, I worked for the Texas Agricultural Experiment Station 20 years, the last 9 years of that in College Station as Director of the Grazingland Animal Nutrition Lab, better known as the "Gan Lab". In this capacity I was tasked with developing and providing tools to monitor the nutritional and physiological status of grazing livestock and wildlife. The primary focus of the Gan Lab is the use of near infrared spectroscopy (NIRS) of manure to determine diet quality. This information is

As a professor and extension specialist in Rangeland Management, my primary role is to provide leadership for statewide educational programming backed by problem-solving research and focused on sustainable use of rangelands. My interests have a central theme to provide various client-groups the ecological foundation essential for the implementation of effective rangeland management. Through participatory research and education, my programming helps build capacity in collaborative conservation, usually in

Rangeland health affects us all. Rangelands comprise about 40% of the landmass of the United
States and provide valuable grazing lands
for livestock and wildlife. They serve as a source of high quality water, clean
air, and open spaces and benefit people through recreation, agriculture, and
mining. The Rangelands West website was created to share information and tools
to care for these extensive and diverse lands.
