The Rangeland Journal publishes original work that makes a significant contribution to understanding the biophysical, social, cultural, economic, and policy influences affecting rangeland use and management throughout the world. Rangelands are defined broadly and include all those environments where natural ecological processes predominate, and where values and benefits are based primarily on natural resources. Papers may present the results of original research, contributions to theory, practice or policy, or new conclusions reached from the review of a topic. Their structure need not conform to that of standard scientific articles but writing style must be clear and concise. All material presented must be well documented, critically analysed and objectively presented. All papers are peer reviewed.

The Rangeland Journal is abstracted and/or indexed in Science Citation Index Expanded, ABOA, Agricola, CAB International, The ISI Alerting Services, and Current Contents (Agriculture, Biology and Environmental Sciences).
