Previous studies examining the flora in the Korean Demilitarized Zone and its surroundings focused only on specific locations or ways to utilize these areas. We investigated vascular plant distribution in this area across the entire Korean Peninsula. Species richness, endemism, and alien species richness were examined for 54,948 occurrence records. Biodiversity and protection status were assessed, and a self-organizing map algorithm was used to divide the flora distribution into an Eastern region (including the Central region) and a Western region. Environmental factors of each distribution type were analyzed. The whole study area had 1,790 taxa of 655 genera and 151 families. The flora of the Central region was similar to that of the Eastern region, which had the richest biodiversity, whereas the Western region contained various invasive alien plants. Most areas with high biodiversity were classified as protected by international agreements. In the self-organizing map, the Eastern and Central regions exhibited large distribution of endemic and northern lineage plants, and the Western region showed high abundances of invasive alien plants. The considerable biodiversity of this area is threatened due to continuous housing development and military operations. Therefore, policies to ensure sustainable conservation of plant biodiversity “hotspots” are required. |
