Lebeckia ambigua is a perennial legume endemic to rangeland South Africa that adapted dry (< 400-mm annual rainfall), infertile and acidic (below pH 5.5Ca) soils. Although it considered the was grazed by mammalian ungulates during its evolution, little known about production, nutritive value for grazing animals or optimal management in an agricultural context, either centre of origin Australia....
In dry lands, semi-circular bund has been considered as a management practice used to restore the ecological revival in terms of vegetation enrichment and soil amelioration. This study was conducted to investigate the effects of semi-circular bunds on vegetation cover and some soil properties in Koteh rangeland, Sistan and Baloochestan province, Iran (2014). Adjacent to the semi-circular bund a...
Rangeland ecosystems shift across dynamic thresholds between differentecological states in response to natural or human-induced factors. These differentecological states are the result of interactions among climate, soils, grazing history,and management practices. The notion of a single ‘‘pristine’’ final state is onlyconceptual in nature, and because of this, dynamic thresholds and the effects...
Extended abstract 1- Introduction Desert dust is formed under the influence of special weather and environmental conditions in desert areas and enters the atmosphere. Local hurricanes caused by surface air instability, passing through dry deserts, remove silt and sand particles from the surface and enter the atmosphere. Desert dust physically, in addition to its ecological effects such as lun...
Digital technologies provide an opportunity to further increase the sustainability and productivity of grasslands rangelands. Three resources are key that change. These soil on which forage grows, forages grow those soils animals use resource as food. This paper describes elements measure monitor these provides some insights combining knowledge controlling animal's utilization through virtual f...
Extensive livestock production has been Mongolia’s major industry for centuries and traditional nomadic herding lifestyle and Mongolia’s expansive rangelands sustain this industry. After the democratic election and economic liberalization in 1992, formerly state-owned collectives were disbanded and Mongolia’s livestock population was privatized. There was no longer a state institution to formal...
Oklahoma is blessed with an abundance of excellent forage resources. Many Oklahoma producers enjoy the benefits of operating livestock production systems on both rangeland and introduced-forage pastures. However, some producers may not be aware of the need for different management strategies for the two ecosystems. Improper management generally results in decreased profitability of the livestoc...
The effects of feeding in different quality rangelands on meat and fatty acids composition Angora goat kids bucks were determined. Twenty male selected from each farm that produces goats the area. There are three separate with previously determined classes (good, medium, low-quality). In farm, among these animals grazed completely rangeland, 7 heads 4-month-old 7-month-old slaughtered. Longissi...
Globally, new combinations of introduced and native plant and animal species have changed rangelands into novel ecosystems. Whereas many rangeland stakeholders (people who use or have an interest in rangelands) view intentional species introductions to improve forage and control erosion as beneficial, others focus on unintended costs, such as increased fire risk, loss of rangeland biodiversity,...
