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...

Species diversity, richness and biomasses (aboveground biomass) and their relationships are the key variables of ecosystems. This study was conducted to determine the relationship of Species Diversity (SD) and Species Richness (SR) with Above-Ground Biomass (AGB) at a local scale at 5 different habitats (shrubland, forbland, grassland, shrub-forbland and forb-shrubland) in Zagros mountains in w...

www.frontiersinecology.org © The Ecological Society of America R – including grasslands, shrublands, savannas, deserts, prairies, steppe, and tundra – comprise 30–40% of Earth’s ice-free terrestrial surface (depending on one’s definition and data sources; Asner et al. 2004) and account for 91% of the world’s grazing lands (Reid et al. 2008). Encompassing watersheds for vast downstream populatio...

This paper reviews current knowledge of the social behavior of grazing beef cattle and discusses how that knowledge can be applied to rangeland cattle management. Cattle herds are composed of social subgroups that influence grazing distribution on rangeland. Grazing distribution is, in part, a learned response; therefore, management strategies that alter the social composition and structure of ...

The potential for wind erosion in South Central Colorado is greatest in the spring, especially after harvesting of crops such as potato (Solanum tuberosum L.) that leave small amounts of crop residue in the surface after harvest. Therefore it is important to implement best management practices that reduce potential wind erosion and that we understand how cropping systems are impacting soil eros...

Although the emerging field of precision livestock farming (PLF) is predominantly associated with intensive animal production, there is increasing interest in applying smart technologies in extensive rangeland systems. Precision livestock farming technologies bring the possibility of closely monitoring the behaviour, liveweight and other parameters of individual animals in free-ranging systems....

Landscape approaches can be subjected to mistakenly targeting a single "best" level of governance, and paying too little attention to the role that cross-scale and cross-level interactions play in governance. In rangeland settings, resources, patterns of use of those resources, and the institutions for managing the resources exist at multiple levels and scales. While the scholarship on commons ...
