The most important decision for successful range management is setting a proper stocking rate. The stocking rate affects rangeland health and productivity, livestock production, and economic returns. Because of its importance, much rangeland research has focused on answering the question, "what is the proper stocking rate?" However, like many important questions in life, it is not easily answer...

Rangeland degradation has been identified as a serious concern in alpine regions of western China on the Qinghai-Tibetan plateau (QTP). Numerous government-sponsored programs have been initiated, including many that feature long-term grazing prohibitions and some that call for eliminating pastoralism altogether. As well, government programs have long favored eliminating plateau pikas (Ochotona ...

Rangeland researchers are increasingly interested in understanding working rangelands as integrated social-ecological systems and in investigating the contexts of human decision-making processes that support system resilience. U.S. public lands ranchers are key partners in rangeland conservation, but the role of women in building system resilience has not yet been explored. We conducted life-hi...

This paper uses a new ecological-economic approach to analyze the role of time in range management in a dynamic and stochastic setting. We first construct a theoretical model of a parcel of rangeland in which time restrictions are used to manage the land. We then show how the dynamic and the stochastic properties of this rangeland can be used to construct two managerial objectives that are ecol...

The timing of application for the management of rangeland grasshoppers (Orthoptera: Acrididae) is critical, especially as insecticides become more specialized and the use of Insect Growth Regulators becomes more widespread. The general seasonal occurrence of adults of many grasshopper species has been well documented; however, their appearance varies widely between years. We analyzed sweep samp...
