Dr. Johnson has been a professor in the Department of Rangeland Ecology and Management at Oregon State University since 1982. His research examines the spatial behavior and movement of livestock on landscapes. He also develops models that predict animal distribution and use. Dr. Johnson is creating methodologies and software that can be used to monitor and quantify rangeland vegetation. He has consulted on rangeland systems world wide and has conducted research projects for the US Department of Agriculture, US Forest Service, US Bureau of Land Management, and private foundations.
