“…2a). Many studies proved that livestock density (i.e., grazing pressure) is usually highest close to water sources or settlements and decreases with distance away from such localities (Andrew and Lange, 1986;FernandezGimenez and Allen-Diaz, 2001;Landsberg et al, 2003;Sasaki et al, 2008;Cheng et al, 2011). According to Stumpp et al (2005) the livestock spatial densities were higher in the first 300 m of the transects from the local centers.…”

“…4), except for the case of a u * value of 0.64 m s −1 , which shows a subtle decline to 0.54 m s −1 . This shift in natural soil, from supply limitedness to an unlimited supply surface, could be explained by the weakening of interparticle bonds as a consequence of trampling (Belnap et al, 2007;Baddock et al, 2011;Macpherson et al, 2008). In some crusted desert soils with higher sand contents, disturbance can lead to increased sand availability and the occurrence of effective abrasion (e.g., Belnap and Gillette, 1997).…”

“…On a physical basis, livestock trampling weakens soil particle bonds to result in dust being released by wind and blown (u * ) into the atmosphere (Baddock et al, 2011;Macpherson et al, 2008). Surface disturbance does not directly cause dust emissions but it does recover surface-available dust (Zhang et al, 2016) and supply sediment to emit.…”

“…They revealed a common consequence of increased dust emissions. Very few studies have focused on the effects of natural disturbances such as livestock trampling for dust emissions, which produced limited data (Houser and Nickling, 2001;Baddock et al, 2011;Macpherson et al, 2008). Scarce and inconsistent data prevent scientists from parameterizing the disturbance effects on dust emissions and to scale their relative contribution to the atmospheric dust.…”

Anthropogenic dust emissions due to livestock trampling in a Mongolian temperate grassland

Abstract. Mongolian grasslands are a natural dust source region and they contribute to anthropogenic dust due to the long tradition of raising livestock there. Past decades of abrupt changes in a nomadic society necessitate a study on the effects of livestock trampling on dust emissions, so that research studies may help maintain a sustainable ecosystem and well-conditioned atmospheric environment. In this study, we conducted a mini wind tunnel experiment (using a PI-SWERL ® device) to measure dust emissions fluxes from trampling (at three disturbance levels of livestock density, N) and zero trampling (natural as the background level) at test areas in a Mongolian temperate grassland. Moreover, we scaled anthropogenic dust emissions to natural dust emissions as a relative consequence of livestock trampling. We found a substantial increase in dust emissions due to livestock trampling. This effect of trampling on dust emissions was persistent throughout all wind friction velocities, u * (varying from 0.44 to 0.82 m s −1 ). Significantly higher dust loading occurs after a certain disturbance level has been reached by the livestock trampling. Our results suggest that both friction velocity (u * ) and disturbance level of livestock density (N) have an enormous combinational effect on dust emissions from the trampling test surface. This means that the effect of livestock trampling on dust emissions can be seen or revealed when wind is strong. Our results also emphasize that better management for livestock allocation coupled with strategies to prevent anthropogenic dust loads are needed. However, there are many uncertainties and assumptions to be improved on in this study.

South American Dry Chaco rangelands: Positive effects of cattle trampling and transit on ecohydrological functioning

Ecological Applications

Livestock production in drylands requires consideration of the ecological applications of ecohydrological redistribution of water. Intensive cattle trampling and the associated increase of surface runoff are common concerns for rangeland productivity and sustainability. Here, we highlight a regional livestock production system in which cattle trails and trampling surrounding an artificial impoundment are purposely managed to enhance redistribution and availability of water for cattle drinking. Based on literature synthesis and field measurements, we first describe cattle production systems and surface water redistribution in the Dry Chaco rangelands of South America, and then develop a conceptual framework to synthesize the ecohydrological impacts of livestock production on these ecosystems. Critical to this framework is the pioshere-a degraded overgrazed and overtrampled area where vegetation has difficulties growing, usually close to the water points. The Dry Chaco rangelands have three key distinctive characteristics associated with the flat sedimentary environment lacking fresh groundwater and the very extensive ranching conditions: (1) cattle drinking water is provided by artificial impoundments filled by runoff, (2) heavy trampling around the impoundment and its adjacent areas generates a piosphere that favors runoff toward the impoundment, and (3) the impoundment, piosphere, and extensive forage areas are hydrologically connected with a network of cattle trails. We propose an ecohydrological framework where cattle transit and trampling alter the natural water circulation of these ecosystems, affecting small fractions of the landscape through increased runoff (compaction in piosphere and trails), surface connectivity (convergence of trails to piosphere to impoundment), and ponding (compaction of the impoundment floor) that operate together making water harvesting and storage possible. These effects have likely generated a positive water feedback on the expansion of livestock in the region with a relatively low impact on forage production. We highlight the role of livestock transit as a geomorphological agent capable of reshaping the hydrology of flat sedimentary rangelands in ways that can be managed positively for sustainable ranching systems. We suggest that the Dry Chaco offers an alternative

Abstract:Mainly attributed to goat and sheep trampling, the sand dunes at the Israeli and the Egyptian sides of the border present contrasting geomorphological conditions. In an attempt to assess the trampling effect upon vegetation, runoff and sediment yield, two pairs of plots and miniplots (each pair contains a trampled plot and a control) were constructed during 1991 and monitored during 1991-1995. In order to assess the impact on vegetation, three pairs of vegetation plots, subjected to light, medium and heavy trampling, were established during 1993 and monitored. In addition, the effect of the micro structures created by the goat hooves (mounds and depressions) were studied in three pairs of plots subjected to medium trampling during 1993 and monitored during 1993-1996. As far as trampling intensity is concerned, the findings indicate an increase in species diversity, density and biomass from the intact crusted surface to the plots subjected to light and medium trampling with a decrease thereafter at the plots subjected to heavy trampling. As for the micro scale, the findings indicate significantly higher plant biomass for the first 2 years at the hooves-formed mini mounds and mini depressions in comparison to intact crusted surfaces, with no significant difference during the third year. Significantly lower runoff and sediment yields characterized the trampled plots implying a reduction in water redistribution. The data point to the differential effect that trampling has upon plants and soil. While increasing annual plant growth along the slope, it hinders runoff flow to the footslope, negatively affecting water availability for footslope vegetation. Recovery, as also supported by chlorophyll and microrelief measurements, was scale dependent (attributed to differential supply of aeolian sand) with estimated recovery for the plots and miniplots being 4-5 and 8-10 years, respectively. The data indicate that upon the cessation of grazing and under similar precipitation regime, recovery time of the biocrust in the Sinai sand dunes may be short, within 5-6 years.
