Another more recent focus of IRM has addressed the ecological restoration of disturbed rangelands. The difference, though, is that fewer resources are available for brush reduction than before because many traditional options to treat brush have become cost prohibitive. New knowledge of the ecological role of woody plants, coupled with an increasing societal appreciation for potential benefits of woody plants, has led to changes in our view of how to manage brush. All elements of resource management, including livestock, wildlife and other profit centers impacted by brush management, be considered in the planning process. Brush or weed problems be matched with appropriate technology.
Economic analysis be a part of the planning process.
Treatment sets are designed to use the strengths of one or more practices to offset inherent weaknesses of others. The potential for synergistic relationships between treatments in combinations is a key factor in the selection process. IBMS provides the underpinning for much of the philosophy and experimentation associated with brush management in Texas. Many researchers and Extension specialists continue to study an integrated systems approach to brush and weed management, whereas prior to IBMS, single-treatment responses were of primary interest. For example, at San Angelo, a high percentage of research effort is being put into development of management systems for redberry juniper and pricklypear cactus using herbicidal, mechanical, biological, or prescribed fire methods, or with systems combining two or more methods.
