- Abstract:
- ... Defining rangelands as anthromes enabled Ellis and Ramankutty (2008) to conclude that more than three-quarters of Earth’s land is anthropogenic; without rangelands, this figure would have been less than half. They classified all lands grazed by domestic livestock as rangelands, provided that human population densities were low; similar areas without livestock were excluded and classified instead a ...

- Abstract:
- ... Control over water supply and distribution is critical for agriculture in drylands where manipulating surface runoff of- ten serves the dual purpose of erosion control. However, little is known of the geomorphic impacts and legacy effects of rangeland water manipulation infrastructure, especially if not maintained. This study investigated the geomorphic impacts of structures such as earthen berms, ...

- Abstract:
- ... The science‐practice gap is often cited as a limitation to successful restoration outcomes; however, the existence of such a gap in information exchange is rarely measured. Here, we quantify the gap by focusing on common recommendations from both scientists (i.e. researchers) and managers (i.e. practitioners, land managers) on what is needed for successful restoration. We surveyed 45 managers asso ...

- Abstract:
- ... Monitoring is a critical component of adaptive management but often weak or missing in practice. We examined grazing allotment files to identify patterns in monitoring and management practices on the Coronado National Forest from 1927 to 2007, and conducted interviews with key informants to understand the mechanisms behind those patterns. Standardized, documented monitoring occurred on a near-annu ...

- Abstract:
- ... Conservation easements have increased dramatically but their social and ecological outcomes are largely unknown. To examine the influence of social relations and institutional structure on easement design and conservation outcomes, we compared two regions where land trusts hold conservation easements protecting large areas of private rangeland: Lassen Foothills, California, and Malpai Borderlands, ...

- Abstract:
- ... BACKGROUND: Pastoralism in the USA began coincidently with the initiation of profound ecological change resulting from colonization in the sixteenth century. Relationships between pastoralism and wildlife conservation in three different contexts of land tenure, environmental legacy, and geography are examined. RESULTS: On the federal rangelands of the Intermountain West, based on limited scientifi ...

- Abstract:
- ... Rangelands encompass 30-40% of Earth's land surface and support 1-2 billion people. Their predominant use is extensive livestock production by pastoralists and ranchers. But rangelands are characterized by ecological, economic, and political marginality, and higher-value, more intensive land uses are impinging on rangelands around the world. Earth Stewardship of rangelands must address both livest ...

- Abstract:
- ... Scientific interest in carbon sequestration on rangelands is largely driven by their extent, while the interest of ranchers in the United States centers on opportunities to enhance revenue streams. Rangelands cover approximately 30% of the earth's ice-free land surface and hold an equivalent amount of the world's terrestrial carbon. Rangelands are grasslands, shrublands, and savannas and cover 312 ...

- Abstract:
- ... Desertification is an escalating concern in global drylands, yet assessments to guide management and policy responses are limited by ambiguity concerning the definition of “desertification” and what processes are involved. To improve clarity, we propose that assessments of desertification and land transformation be placed within a state change–land‐use change (SC–LUC) framework. This framework con ...
