“…The pool of plant species, that is, the source of seeds and diaspores and the potential for colonization of species, plays a major role in the restoration, by influencing the process of spontaneous succession (Strykstra et al 1998; Zobel et al 1998; Řehounková & Prach 2008). Therefore, the characteristics of the landscape should be properly taken into account for any restoration initiatives (Bakker et al 1998; Prach et al 2001; Son et al 2020), and in our case, may have a higher success if adjacent to patches of the reference ecosystem (Buisson et al 2006).…”

Quarry restoration is difficult to implement due to the scarcity of the original soil. The restoration of Mediterranean dry grasslands to mitigate similar ecosystem/habitat loss is thus still a developing process. So far, very few studies have created artificial substrates to address the lack of soil. In the La Crau plain (Southeastern France), quarries were established in an ancient Mediterranean steppe‐like dry grassland. Once the remaining grassland zones were protected in 2001, quarries were extended over former intensive orchards established on the grassland in the 1990s before it was protected. Now, restoration has to be done without the unaltered protected grassland soil but with the soil from orchards, which contains fertilizers spread during the orchard exploitation. To recreate a more suitable substrate, the orchard topsoil was mixed with poor substrate materials directly extracted from the quarry (0–30 mm pebbles with sandy matrix). Different substrate mixtures were tested with or without sowing the dominant species of the grassland, a perennial grass: Brachypodium retusum (and an annual grass B. hybridum). After 5 years of monitoring, our results show that raw substrate materials (100%) limit the establishment of all species, and that, at the opposite, orchard topsoil (100%) favors a significantly higher species richness of target and non‐target species. The recommended substrate mixture to reach a compromise between high target species cover and low non‐target species cover is composed of 50% raw quarry material and 50% arable soil. Sowing Brachypodium not only limits non‐target species richness and cover but also reduces target species richness establishment.

“…The species richness of vegetation was defined as the number of plant species recorded in each quadrat (1 × 1 m) ( Han et al., 2021 ). The percentage of cover of all the species in each quadrat was visually estimated following the methods of Son et al. (2020) and evenness (Hill's Index) was calculated ( Hill, 1973 ).…”

The construction and continued use of transportation infrastructure, specifically roads, has had a significant global impact on biodiversity and the environment. The Republic of Korea, or South Korea, has a road density of 1.13 km/km2. So far, three nationwide studies about vertebrate road-killed species have been reported, showing bias towards medium to large mammals, the most common victims being the Korean water deer (Hydropotes inermis), Korean hare (Lepus coreanus), Siberian roe deer (Capreolus pygargus), and the common raccoon dog (Nyctereutes procyonoides). Road-kills, or wildlife-vehicle collisions (WVCs), tend to occur in or near preferred habitat types or in highly fragmented areas, with roads additionally being linked to habitat fragmentation and loss. Alongside WVCs and habitat effects, information about other adverse effects on biodiversity is scant, although there are reports that heavy metals and other pollutants from road runoff impact marine biodiversity, vegetation, soil, and groundwater. Furthermore, roads have been linked to a prevalence of invasive plant species. To mitigate road impacts, the South Korean government has constructed, with mixed results, 530 wildlife crossing structures, mainly including overpasses and tunnels. To mitigate road impacts more effectively, the country will need more construction, monitoring, and consistent management of wildlife crossing structures. Further, incorporating plans for wildlife crossing structures in early stages of road development will be required.
