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.

RNG 350 - Grassland Ecosystems - Designed to acquaint students with
grassland systems with emphasis on North American grasslands and comparison with
grasslands of other continents. Emphasis of the course is on system structure,
process and function. Major consideration is placed on phytoedaphic and zootic
RNG450/550 – Landscape Ecology and Analysis - This course introduces
students to the principles and terminology of landscape ecology in a rangeland
context. We examine the pattern and distribution of physical and biological
landscape elements across a terrain and seek relationships between element
location and environmental parameters. Landscape dynamics through time are
quantified, analyzed, and mapped.
RNG442/542 - Range Animal Relations - Domestic and wild animal use of
rangelands as related to environmental factors, palatability, food habits,
nutrition, physiography, and their effects on management of rangeland-animal
RNG468/568 – International Range Mangement - This course discusses the
problems and potentials of range management techniques as they are applied in
developing countries. This is accomplished by examining traditional development
actions in light of social, economic, ecological, and technical constraints.
