RNG 352 - Grassland and Shrubland Ecosystems - Examines the primary characteristics of each ecoregion throughout the semiarid and arid areas of North America. Covers basic ecology of each region, including a discussion of important plant species, climate patterns, soil types, and topography.

RNG 355 - Desert Watershed Management - Principles and methods in managing rangeland for optimum production and regulation of water yields, as well as maintaining soil stability and on-site productivity. Effects of grazing herbivores and their potential as land use, manipulative tools. Concepts of arid land hydrology, with emphasis on the resultant effects on runoff quantity and quality.

RNG 441 - Range Analysis - Techniques used to describe vegetation in shrub-lands, grasslands, and forests. Use of measurements in resource management. Course is field-oriented, emphasizing both theory and practice of wildland inventory methods.

RNG 490 - Range Management Planning - Administration and management of rangelands; planning processes involving goal setting, inventories, personnel management, environment, conflict resolution, and other constraints necessary for decision-making. Use of data collected from field problems to support the execution of class plans. Field trip required.
