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 ...
Methodology For Assessing and Monitoring Rangeland Vegetation in Central Asia
The research objectives has two folds aiming at:
1. Fine tuning/developing a toolkit for monitoring and assessing rangeland vegetation at the
landscape level using up-to-date technologies; and
2. Carrying out an integrated ...
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 ...
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 ...
Rangeland rehabilitation in the southern part of the Mediterranean basin
Rangelands of the southern part of the Mediterranean basin have for centuries provided forage for livestock and wildlife. Now their role as providers of ecosystem services and goods is being widely recognized by local ...
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 ...
The effect of grazing exclusion on vegetation characteristics and plant community structure in arid lowland pastures
Rangelands are the mainstay of pastoral livelihoods worldwide. Within rangelands, there are landscape depressions or lowlands characterized by high production potentials with their unique edaphic and hydrologic properties. ...
Screening for Cold Tolerant Cactus Species (Opuntia ficus-indica) for West Asia Region
The identification of the cold tolerant Opuntia species to increase their
cultivation in West Asia region where the cold winter conditions limit their
adaptation is the primary yet the most critical step. The International ...
