“…Previous research on this technique has focused on (1) screening proper slope-protection plants and optimizing their combination (Karim and Mallik, 2008;Tormo et al, 2008;Beikircher et al, 2010), (2) the vegetation outcomes in terms of ecology, botany and climate (Martínez-Ruiz et al, 2007;Bhattarai et al, 2008;González-Alday et al, 2008;Alday et al, 2010;García-Palacios et al, 2010), (3) optimizing the component ratios of artificial soils (Gao et al, 2007) and describing the influential factors for revegetation (Alday et al, 2010;Ai et al, 2012), and (4) the stability and erosion resistance of cut slope protection from the perspective of geotechnical engineering (Lee et al, 2007). However, the validity of the rock fragments as backfill soil has not been evaluated.…”

“…There is evidence that as the grass cover level increases, the soil erosion rate decreases (Gyasi-Agyei et al 2001). For example, buffel grass (Cenchrus ciliaris) is one of the preferred species for revegetation of railway embankments in Australia (Bhattarai et al 2008); in some of the areas (Central Australia and Western Queensland), this grass spreads readily in soils with crumbly or soft surfaces, but it needs to be handled with care because it has the potential to become a weed (Cameron 2004). This species, in combination with Japanese millet (Echinochloa esculenta), has also been used successfully in controlling soil erosion in the semi-arid tropics of Central Queensland.…”

Railway Disturbances on Wildlife: Types, Effects, and Mitigation Measures

In this chapter, we review the level of disturbance caused by railways due to noise and vibration, air, soil and water pollution, and soil erosion. There is evidence that soil and hydrology contamination may affect vegetation and aquatic fauna while noise can affect terrestrial vertebrates. In fact, noise, light, and vibration due to railways have been observed to reduce the abundance and richness of some insects, amphibians, and birds, and to cause avoidance behaviour on predators. Interestingly, reptiles, some bird species, small mammals, and large mammals seem to ignore rail traffic and benefit from the vegetation planted in the railway verges that provide food and shelter. Some engineering structures have been implemented to reduce the effects of railway disturbance: rail fastenings, rail dampers, under-sleeper pads, and noise barriers are applied to minimize noise and vibration; washing with water and cleaning the ballast are used to mitigate soil pollution; and grass plantation, the use of gypsum and application of compost/mulch coverage, are applied to control soil erosion.

“…3). Whenever treatments were associated with high germination rates (88%-90%), 25% sulfuric acid solution for 15 minutes ensures optimal germination of F. rubra seeds, soaking in a 50% sulfuric acid solution for 10 minutes ensures optimal germination of Lolium perenne seeds, soaking in a 50% sulfuric acid solution for 15-20 minutes ensures optimal germination of Poa pratensis seeds (Salehi and Khosh-Khui, 2005), and a 4-minute exposure to a 100% sulfuric acid solution ensures optimal germination of a variety of Buffel grass (Bhattarai et al, 2008).…”

Efficient germination of fescue seeds is essential for successful establishment of meadows and pastures. This research was conducted to ascertain the effects of various acid and temperature treatments on seed germination in three fescue species: Festuca rubra, F. ovina, and F. pratensis. Seeds from different cultivars, populations, or lots were exposed either to four concentrations of sulfuric acid at three different time intervals (12 treatments) or six different temperatures at three different time intervals (18 treatments). Despite all belonging to the genus Festuca, the seed from different species responded differently to the treatments. The three optimum treatments for F. rubra seed involved soaking in a 75% solution of sulfuric acid for 20 minutes (improved the germination rate by 19%), soaking in a 50% solution of sulfuric acid for 30 minutes (improved the germination rate by 18%) and exposure to either 60°C or 70°C for 90 minutes (improved the germination rate by 17%). For F. ovina seed, optimal treatments included soaking seeds for either 10 or 20 minutes in a 50% sulfuric acid solution (both treatments improved germination rates by 13%) or exposing seeds for 30 minutes in a 25% sulfuric acid solution and 80°C for 60 minutes (improved germination rate by 12%). Two optimal treatments were identified for F. pratensis seed. Whereas the first involved soaking the seeds in a 75% sulfuric acid solution for 30 minutes (improved germination rates by 22%), the second involved either exposing the seeds to 90°C for 90 or 60 minutes, or exposing the seeds to 80°C for 90 minutes (improved germination rate by 21%). Our findings indicate that if fescue seed is to be sown during the autumn (two to three months after seed collecting), treating it with acid and temperature can significantly enhance its germination.
