“…In an attempt to control the soil and water losses and to improve the ecological environment of the area, the Chinese Central Government has enacted a policy entitled "Shift from Cropland to Forest or Grassland" for the restoration of vegetation since the late 1990s. Vegetation has become a tool in restoring the slope's physical condition and stability throughout the succession process (Osman and Barakbah, 2011). Caragana korshinskii (CK), a legume shrub, has strong reproductive and self-renewal ability and is a valuable shrub species in the hilly-gully zone of northern China (Niu et al, 2003).…”

“…It has been generally recognised that plant water uptake is affected by biomass (both above-and belowground) as well as physiological factors (Lambers et al 2008;Osman and Barakbah 2011;Jones 2013). Interestingly, the PC biplot (Fig.…”

Background and aims Vegetation stabilizes slopes via root mechanical reinforcement and hydrologic reinforcement induced by transpiration. Most studies have focused on mechanical reinforcement and its correlation with plant biomechanical traits. The correlations however generally ignore the effects of hydrologic reinforcement. This study aims to quantify the hydrologic reinforcement associated with ten woody species and identify correlations with relevant plant traits. Methods Ten species widespread in Europe, which belong to Aquifoliaceae, Betulaceae, Buxaceae, Celastraceae, Fabaceae, Oleaceae and Salicaceae families, were planted in pots of sandy loam soil. Each planted pot was irrigated and then left to transpire. Soil strength, matric suction and plant traits were measured. Results Transpiration-induced suction was linearly correlated with soil penetration resistance for the ten species due to their different transpiration rates i.e. both suction and soil penetration resistance induced by Hazel and Blackthorn (deciduous) were five times greater than those by Holly and European Box (evergreens). Specific leaf area and root length density correlated with hydrologic reinforcement. The root:shoot ratio correlated best with the hydrologic reinforcement. Conclusions Specific leaf area, root length density and root:shoot ratio explained the tenfold differences in hydrologic reinforcement provided by the ten different species.

Abstract. The rise of awareness on environmentalism has demanded that all parties involved in built environment to implement green technology in their construction projects. Great care must be taken when designing a green roof system including the selection of plants and appropriate substrates. This study was performed to investigate the soil-root composite strength of two types of green roof vegetation (A. Ficoidea and Z. Japonica) at different growth periods for up to 6 months. Both plants were planted in six plastic plots (45 cm × 29 cm × 13 cm) containing a mixture of perlite, vermiculite and organic soil. Every two months, a series of direct shear tests were conducted on a sample from each species to determine the root-soil shear strength. The tests continued until the 6 th month. The average results showed that Z. Japonica had higher soil-root shear strength (49.1 kPa) compared to A. Ficoidea after two months of growth. In the 4 th month however, A. Ficoidea managed to surpass Z. Japonica (28.7 kPa versus 18.5 kPa) in terms of shear strength. However, their average peak shear strength decreased sharply compared to the previous month. Lastly, in six months, A. Ficoidea sustained a higher average peak soil shear strength (56.5 kPa) compared to Z. Japonica (14.3 kPa). Therefore, it can be concluded that A. Ficoidea may offer a better soil reinforcement than Z. japonica and thus it could potentially be a good choice of green roof vegetation.
