The San Francisco Bay Area in California, USA is a highly heterogeneous region in climate, topography, and habitats, as well as in its political and economic interests. Successful conservation strategies must consider various current and future competing demands for the land, and should pay special attention to livestock grazing, the dominant non-urban land-use. The main objective of this study...

Prescribed fires are used to manipulate and manage rangelands, but effective monitoring techniques are needed to ensure that management goals and objectives are being met. The application of an effective fire program on rangelands is not a simple task. Overgrazing by livestock since the early development of the livestock industry has altered the vegetative complex on most rangelands with an inc...

This paper identifies new ways of moving from land degradation towards sustainable land management through the development of economic mechanisms. It identifies new mechanisms to tackle land degradation based on retaining critical levels of natural capital whilst basing livelihoods on a wider range of ecosystem services. This is achieved through a case study analysis of the Kalahari rangelands ...

The Santa Rita Experimental Range is 100 years old this year, providing an occasion to celebrate and to reflect. The first of many experimental ranges in the United States, the Santa Rita was founded at a time when both range science and plant ecology were in their infancy. The purpose was to conduct research that would aid in the management of Southwestern rangelands by public agencies and pri...

In this essay, Sahand Shaibani employs a Freudian psychoanalytic approach to discuss the influence of irrational and emotive forces in the American judicial process. He argues that the adversarial legal process serves the important psychological function of sublimating aggression, and that trial courts present a forum for the recreation of the Oedipal triangle, wherein the judge is unconsciousl...

Introduction Different barley varieties have been shown to affect in vitro dry-matter digestibility (IVDMD), ruminal starch digestion and animal performance (Boss and Bowman, 1996). Some of these differences may be due to differences in site and extent of nutrient digestion among barley varieties. Little information is available on digestive characteristics of different barley varieties and sev...

This paper analyzes regulatory design for agroecosystem management on public rangelands. We present an informational and institutional environment where three of the most prominent regulatory instruments on public rangelands – input regulation, cost-sharing/taxation, and performance regulation – can be defined and compared. The paper examines how the optimal regulation is shaped by the informat...
