“…In recent years, intensive studies have been conducted concerning the effects of grazing exclusion or degradation on grassland -especially on vegetation [5], soil nutrients [6], and soil seed banks [7]. However, studies on the effectiveness of grazing exclusion have had many inconsistent results.…”

“…However, its effects on rangeland are not yet clear and still need further studies. Previous studies by Shi [30] and Shang [31] showed that although grazing exclusion could reduce soil organic carbon storage in rangeland, it could improve vegetation cover. Reduction of soil organic carbon storage in rangeland may show a negative effect on the rangeland in the future.…”

Abstract:The Three Rivers Source Region of the Qinghai-Tibet Plateau is a key area that has extensive impacts on much of the population and economy of China as well as several Southeast Asian countries. The rangeland in this area has undergone degradation, the driving factors of which have been extensively investigated in previous studies. However, the effect of policy on rangeland was not analyzed by subdividing the study period according to the timing of the rangeland policies. The role of dry conditions during the process of degradation has not been studied. Therefore, the period from 1984 to 2009 was subdivided into five periods according to the timing of the relevant government policies based on long-term field investigation. The mean annual normalized difference vegetation index (NDVI) and its relationship to dry conditions, policy, temperature, precipitation, and moisture index were analyzed for the five periods. According to our analysis, dry conditions mainly occurred in non-vegetation-growing months, and they did not affect the status of the rangeland. The privatization of rangeland and livestock caused the number of livestock to increase, resulting in a decrease in the mean annual NDVI from 1984 to 1993. The policies of "Green-to-Grain" and eco-migration caused livestock numbers to decrease and the NDVI to increase after 1994. Physical factors such as temperature, precipitation, and moisture also affected the status of the rangeland. Increased temperature had positive effects on rangeland in most areas, but its effect was offset by increased numbers of livestock from 1984 to 1993. Precipitation had positive effects only in drier areas in which the precipitation in the vegetation-growing months was less than 400 mm. In general, the policies of "Green-to-Grain" and eco-migration improved the status of rangeland, and helped improve sustainable use of the rangeland. The methods used in this study could be applied to other case studies of rangeland. Governments should continue to implement compensation policies to maintain the improved condition of rangeland in the area and expand those policies to other rangeland areas.

“…Besides unsustainable grazing management, global climate change, excessive herbivory, soil disturbance from small mammals, and historical-cultural impediments, overgrazing is regarded as one of the major causes of degradation (Zhou et al, 2006;Harris, 2010;Wu et al, 2014). Enclosure is widely accepted as a valuable tool to restore degraded grasslands of QTP (Ma et al, 2002;Dong et al, 2007b;Shang et al, 2013). It could improve the net primary production and modify species composition due to the selective grazing behavior of animals (Zheng et al, 2005;Wu et al, 2013).…”

“…It could improve the net primary production and modify species composition due to the selective grazing behavior of animals (Zheng et al, 2005;Wu et al, 2013). Other benefits, especially the benefits of long-term enclosure, were widely reported (Dong et al, 2007b;Mayer et al, 2009;Wu et al, 2009b;Wu et al, 2010;Fernández-Lugo et al, 2013;Shang et al, 2013). However, grazing is the most fundamental grassland utilization, long-term grazing exclusion might be a kind of resources waste for animal husbandry production and it had severe negative effects on the vegetation restoration and feed nutrients (Cuevas and Le Quesne, 2005;Wu et al, 2009a).…”

Short-term grazing exclusion has large impacts on grassland vegetation and nutrition. In order to study the effects of the short-term rest on aboveground biomass, forage quality, and soil moisture on alpine pasture of the Qinghai-Tibet plateau, cages were used to exclude grazing from July to October on summer pasture used by three typical farms with different stocking rates. The results showed that, within the same month during the forage growth period, the dry weights of the edible forage in the cages were significantly higher than that out of the cages (P < 0.05) under heavy grazing pressure (from 2.47 to 2.48 animal unit equivalent AUE ha -1 ). Within the same soil depth, soil moisture was significantly different in, and out of, the cages (P < 0.05) and it decreased with depth. The crude protein content for forages in cages was significantly higher than that out of the cages for the farm with a heavy stocking rate and the neutral detergent fiber was significantly lower. This shows that short-term rest periods could effectively increase dry weight and crude protein content of the edible forage for farms with heavy stocking rates. This short-term rest management strategy is recommended for farms with a heavy stocking rate.
