Statistical analysis is done on the change in ground object area in the research area. The results show that the area of vegetation, bare land and mining area has changed greatly after ecological restoration in the study area.

After ecological restoration, there is a clear spatial correspondence between the bare land and the area with increased vegetation and the area with reduced mining area. The reason why the vegetation area increased slightly and the bare land area increased significantly after ecological restoration in the study area is that the local natural geographical conditions are harsh and the ecological restoration project is completed soon.

Over 90% of turtles were able to successfully climb a 36° slope. At steeper inclinations, female climbing success drastically dropped. Furthermore, climbing steeper inclinations is more time and energy consuming and might limit habitat use. Our results suggest that body size is the limiting factor of turtle climbing ability, regardless of sex. However, larger and less agile female turtles are especially susceptible to steep shorelines, since their fitness directly depends on their ability to reach favourable nesting sites. Based on our results, we suggest that slopes of artificial shorelines in European pond turtle habitats should not exceed 36° angles.
