“…Consequently, it may be interesting to reduce the weight of hemicryptophytes in hydroseeding in Mediterranean climates, increasing the percentage of therophytes and including seeds of chamaephytes. Jaúregui et al (2013) recommended a higher percentage of legumes to reduce litter accumulation on road slopes; however, our results showed a regressive trend of this group over time, so increasing their percentage in seed mixtures can lead to a lower plant cover. Arenas et al (2015) indicated that woody-planted vegetation did not have a facilitating effect on natural colonisation.…”

Revegetation effectiveness requires long-term monitoring. We analysed 50 road slopes 5–8 years and 22–25 years after revegetation. Plant cover and diversity increased over time, with differences between slope types; herbaceous cover increased greatly between revegetation works and 2002 and was similar in 2002 and 2019, while woody cover decreased from revegetation to 2002 but increased greatly between 2002 and 2019. Plant colonisation was more intense on embankments, but could also be achieved on roadcuts (2.4 points on average over a maximum of 5). The presence of sown species decreased over time, but the presence of planted species remained stable. Hydroseeding had poor results in terms of the resulting plant cover, but nevertheless succeeded in slowing erosion at least sufficiently to allow early plant establishment and thus the start of colonisation. The similarity between surrounding vegetation and the slopes was greater in roadcuts. Roads are a gateway for invasive plants. Native species can improve the results, but many are missing from the market. Slopes’ plant cover changed over time; long-term studies are required.

“…The revegetation of embankments is an effective method for maintaining road stability and controlling erosion (Grant et al, 2011), and road slopes are usually planted with legumes to improve soil nutrient content because of the N-fixing capability and high yield of this plant family (Jáuregui et al, 2013;Yuan et al, 2015). Different features of road development have different negative consequences for the environment (Liu et al, 2008), and slope aspect is a primary factor affecting plant composition and soil properties (Warren and Robert, 2010).…”

Objectives: Coronilla varia L., a leguminous herb, is widely used in vegetation restoration programs on road embankments to enhance soil nutrients. Our hypothesis is that, under identical climatic conditions, plant and soil properties are determined by the slope aspect and stand age of legume plantations. Methods: We collected soil samples and investigated plant diversity in an age sequence of 0-, 4-, 10-and 20-year-old C. varia L. plantations and natural grasslands. Results: Stand age, rather than slope aspect, was found to be the main factor influencing the soil and plant feedback on the embankments. Planting C. varia L. on the embankments could enhance soil nutrients and improve the soil quality to the level of a natural grassland after 20 years of plantation. The plant diversity and species number were steady after C. varia L. had been established for 10 years. Conclusions: Planting C. varia L. on embankments is an effective method for enhancing soil nutrients and maintaining ecosystem stability in the Guanzhong Basin, China.
