Biological diversity (biodiversity) is an essential issue in conservation and environmental impact assessment (EIA). Though Korea is relatively small, the country harbours over 29,800 species, making biodiversity and ecosystem conservation a central issue when an EIA is undertaken during development site selection. Indeed, an unfavourable biodivers...

As a consequence of warming temperatures around the world, spring and autumn phenologies have been shifting, with corresponding changes in the length of the growing season. Our understanding of the spatial and interspecific variation of these changes, however, is limited. Not all species are responding similarly, and there is significant spatial va...

We studied the winter foraging activity of the endangered Red-crowned crane (Grus japonensis) and the vulnerable White-naped crane (Grus vipio) in the Cheolwon area of the Civilian Control Zone (CCZ) area of South Korea, adjacent to the Demilitarized Zone with North Korea. Due to its limited development, the CCZ is one of the most critical migrator...

Even though environmental impact assessments (EIAs) have been an important tool for environmental decision-making, most EIAs are published as a mix of text and tabular data that is not easily accessible to or understandable for the public. In this paper, we present a decision support system (DSS) that supports the decision-making of stakeholders in...

In recent decades, rapid industrial growth has accelerated the construction of new roads, which has led to the destruction and isolation of wildlife habitats. Newly constructed roads affect wildlife in many ways. In particular, fatal wildlife-vehicle collisions (WVCs) have a direct impact on wildlife. A substantial number of WVCs occur every year o...

The effects of climate change are becoming apparent in the biosphere. In the 20th century, South Korea experienced a 1.5 °C temperature increase due to rapid industrialization and urbanization. If the changes continue, it is predicted that approximately 15–37% of animal and plant species will be endangered after 2050. Because butterflies act as a g...

In contrast to other fields, environmental protection (e.g., habitat protection) often fails to include quantitative evaluation as part of the existing environmental impact assessment (EIA) process, and therefore the EIA is often a poor forecasting tool, which makes selecting a reasonable plan of action difficult. In this study, we used the Habitat...
