Korean Expat Community for National Disasters

• 목록

  Every Korean has a special feeling for pine trees. The second verse of Korea's national anthem goes: "The pine tree on Namsan Mountain, standing firm through wind and storm." From childhood, Koreans have sung those words hundreds of times, and through them, the pine tree became a symbol of the Korean spirit — unyielding in the face of any hardship. It has always been there, in classical poems and folk paintings, on the hillsides we climbed during holidays. The pine tree is not just a plant; it is woven into the very soul of Korean identity. And now, that tree is quietly disappearing.

  The culprit is the pine wood nematode — a parasitic worm just 1mm in length. It travels into pine trees carried by a beetle called the pine sawyer, and once inside, it completely blocks the pathways that carry water and nutrients through the tree. Within a year, the tree is dead. There is no vaccine, no cure. The only response is to find the infected tree, cut it down, and fumigate it. Some have called it "AIDS for pine trees" — because once infected, there is nothing left to do.

The scale of the damage is already severe. Last year, 1.49 million trees were killed by pine wilt disease, and the spread is accelerating as climate change increases the activity of the carrier beetle and drives the natural decline of pine forests. The damage has been concentrated in the southern regions of Gyeongnam, Gyeongbuk, and Jeju, but in recent years the disease has been creeping northward toward the Seoul metropolitan area and Gangwon Province.

  The problem doesn't end with the trees dying. Dead trees become breeding grounds for other pests and dramatically increase the risk of wildfires and landslides. Analysis of the devastating simultaneous wildfires that swept across the country in March 2025 suggests that dead trees killed by pine wilt disease served as fuel, alongside the effects of climate change. Pine wilt disease can be the starting point for broader forest disasters. Pine forests cover approximately 17% of Korea's land area and 27.5% of its total forest area, generating an estimated 71 trillion won in public value each year through timber production, tourism, and recreation. This is not simply an environmental issue — it carries enormous economic and cultural stakes.

  The government is not standing still. The Korea Forest Service has established its first-ever mid-to-long-term national pine wilt control strategy covering 2026 to 2030, pursuing a package of responses including region-specific control measures, AI-based monitoring systems, and the development of disease-resistant pine varieties. In April of this year, 200 disease-resistant pine saplings were planted in a pilot afforestation project in Yeongdeok, North Gyeongsang Province — the first case of its kind. With no cure available, the strategy is to grow trees that can withstand the disease on their own. Have you ever imagined Korean mountains without pine trees? For pine trees to disappear from Korea's landscape would mean losing more than just one species of tree. It would mean losing the scenery we remember, the nature we inherited, and the enduring symbol that has lived in our national anthem for hundreds of years.
