If the air temperature rises due to climate change, the environment suitable for plants will shift northward. In that process, the most affected plants will be alpine plants that grow on high mountains in a low-temperature environment. If the air temperature continues to rise, alpine plants may eventually lose their habitat and almost disappear from Japan. There is also a prediction that the areas suitable for beech forest in Shirakami-Sanchi, a UNESCO World Heritage site, will decrease to around 20%. On the other hand, bamboo, which favors warm climate, seems to be expanding its power northward.
