Tree line on Mt. Fuji reaches new heights
The tree line near the halfway point of 3,776-meter Mount Fuji, considered the uppermost limit where such plants can thrive, has steadily climbed over the past four decades and global warming offers the best explanation, researchers say.
A joint study by Niigata and Shizuoka universities also found that Japanese larch trees, known for their stunted posture as if to hug the wind-swept terrain, stand more upright these days. The only possible explanation appears to be the shift in global warming.
The latest findings show that the upper end of a Japanese larch forest, which defines the timberline, had moved 30 or so meters upward along the slope from 40 years earlier, and the number of trees in the area had also increased.
