Measurement of the aboveground biomass of some rangeland species using a digital nondestructive technique
Plant biomass is usually assumed to be positively correlated with canopy cover. Measurements of
canopy cover can now be easily and precisely made through image processing of high-resolution
digital photography. This study ...
Grasslands in 'Old World' and 'New World' Mediterranean-climate zones: past trends, current status and future research priorities
Despite their ecological, economic and social importance,
grasslands in areas with Mediterranean climates
continue to receive limited scientific, political and
media attention. The main objectives of this review
are to ...
Cattle use of perennial streams and associated riparian areas on a northeastern Oregon landscape
Stream and riparian health is a major concern for state and federal land management agencies that are charged with oversight of extensive land holdings in the mountain west of the United States. Several federal agencies ...
Financial incentives: Possible options for sustainable rangeland management?
Large-scale mismanagement of natural resources emanating from lack of appropriate policies and reg- ulatory framework is arguably one of the reasons that led to resource degradation and poor livelihoods in many countries ...
Cattle use of off-stream water developments across a northeastern Oregon landscape
Water developments have been considered a fundamental tool for dispersing livestock and reducing livestock impact on riparian and aquatic habitats associated with perennial streams. Quantifying the efficacy of water ...
A Knowledge-Based Approach for Mapping Land Degradation in the Arid Rangelands of North Africa
Rangelands cover about 82% of the arid area of Morocco. It is generally acknowledged that these areas are threatened by desertification.
Monitoring desertification requires accurate knowledge about the current status of ...
Spatial Occupancy Patterns and Activity of Arid Rangeland Cattle Grazing Small Riparian Pastures
The spatial occupancy patterns and activity of cattle grazing three riparian pastures was investigated in northeastern Oregon using Global Positioning System (GPS) collars logging at 1-sec intervals. Cattle consistently ...
