Accelerated erosion of streambanks in grazed riparian pastures is of concern to land managers. We tested the hypothesis that providing cattle free-choice off-stream water and trace mineralized salt would lessen negative impacts of grazing on cover and stability of streambanks compared to pastures lacking these amenities, and may therefore reduce the potential of accelerated erosion. The study w...
Some 60% of Australia% beef cattle are located in the tropics and subtropics, grazing, in general native pastures of low digestibility and N content. Production per head is low, as also are reproductive rates. The nutritional problem centres around the low contents of phosphorus, sulphur and nitrogen in pastures from June to December. This paper discusses responses in breeding cattle to supplem...
Tall fescue (Festuca arundinacea Schreb.) infected with the endophyte Neotyphodium coenophialum ([Morgan-Jones and Gams] Glenn, Bacon, and Hanlin) causes fescue toxicosis in cattle grazing the forage, but effects of the endophyte were considered to be abated soon after removal of the animals from pastures. Tasco-Forage, a proprietary extract from the brown seaweed Ascophyllum nodosum, is a know...
We study forestry in the Sámi people homeland to understand an ongoing conflict between conventional and maintaining forests as reindeer pastures vital for indigenous livelihood. Conventional logging affects by creating stand densities suboptimal lichen growth decreasing old-growth forest areas, both of which are essential survivability during subarctic winter. Our model includes timber product...

Silvopasture is the intentional integration of trees, forages, and livestock. Benefits this agroforestry practice include shade for livestock, nutritious forage, reduced wind speed in pastures, as well ecosystem services tree products. The literature indicate that some livestock producers are interested silvopasture, but little known about their establishment preferences if they vary by demogra...
Matching the trend seen among the major large rivers of the globe, the Amazon River and its tributaries are facing aquatic ecosystem disruption that is affecting freshwater habitats and their associated biodiversity, including trends for decline in fishery resources. The Amazon's aquatic ecosystems, linked natural resources, and human communities that depend on them are increasingly at risk fro...
Silvopasture practices are being advocated as a means of maintaining pine forest acreage in the southeast United States; however, scientific data on the design and management for optimum tree growth are lacking. Studies were conducted near Booneville AR to determine the effects of weed control, irrigation, soil fertilization and protection from cattle grazing on the establishment of loblolly pi...
