Invasive but rare plants take root on Hokkaido mountain, stirring debate over eradication

A non-native plant species, komakusa, was introduced to Hokkaido by climbers and is now taking root on mountains in the region. This non-native species, also known as the queen of alpine plants, has spread across a significant area near the hiking trail on Mount Tarumae, a 1,041-meter peak in Shikotsu-Toya National Park. There is a debate over whether to eradicate this invasive plant due to concerns about its potential impact on the ecosystem.
Komakusa is a perennial in the poppy family, native to Japan's central Chubu region and higher elevations. It is designated as near threatened on Hokkaido's Red List. The plant spreads through seeds and can be purchased at gardening shops or on flea market apps. Its adaptability to various environments may contribute to its spread.
While the park office has not found evidence of komakusa negatively impacting the ecosystem, the national government and volunteers continue efforts to eradicate it, aiming to preserve the original natural landscape.
