Rangelands are vast landscapes that cover most of western North America and the earth, including about 53% of Idaho’s land cover. Rangeland has a legacy of multiple use that has affected where and how people live, work, and recreate. Hence, this curriculum is designed to encourage students to:
- Examine the ecological principles that cause these grasslands, shrublands, woodlands, and deserts to change or stay the same.
- Explore how humans use and manage rangeland.
- Address modern challenges of rangeland management with broad thinking and new, sustainable practices to maintain and restore rangeland and the human communities that rely on them.
The curriculum includes recorded lectures and PowerPoint presentations, noteguides, activities, videos, and readings. The development of the curriculum was a cooperative endeavor of the University of Idaho Rangeland Conservation program and Department of Agricultural and Extension Education, and the Idaho Rangeland Resources Commission. The curriculum was made possible by the David Little Livestock Range Management Endowment, the University of Idaho, and the Idaho Rangeland Resources Commission.
This curriculum is also offered at the University of Idaho as a campus, online, and dual-credit course (REM 151 Rangeland Principles). For more information on these course, contact Karen Launchbaugh (firstname.lastname@example.org) or April Hulet (email@example.com).
Classroom use of these materials are free. The curriculum can be modified and adjusted to meet each teacher’s specific needs.

Forces of Change
Rangeland is dynamic. Drastic changes can be observed among seasons within a year and among years and decades. There are five major factors that cause rangeland to change over time, herbivory, fire, invasive plants, weather and climate, and fragmentation due to human influences. In this lesson, you will be introduced to forces of change, ecological services and resources, and tools we have for management.
Succession is a directional change of plant communities over time. These shifts are often predictable and gradual, however, on rangeland successional changes may be altered. For example, invasive annual grasses make it difficult for native perennial plants to thrive to altered fire regimes. In this lesson, you will learn about primary and secondary succession and how land managers use succession principles to rehabilitate rangeland after disturbances.
State-and-Transition Models (STM) provide a framework for understanding our current plant communities and how they may change following a disturbance, naturally over time, and/or with shifting climatic patterns. In this lesson, you will learn about STM including steady states, transitions, and thresholds. You will also learn about stepwise degradation and be provided with several rangeland examples.
Start by watching “State and Transition Models” presentation and complete the noteguide as you watch.
