A numerous number of American trees move to relocate in the West and North. The weather is getting so how that makes the trees migrate due to climate change.
USA Today reported that climate change is getting worse and makes the American trees move to the West and North. Specifically, it's the man-made climate change that makes the temperature warm and deviated rainfall that makes it hard for the trees to survive in such environment, causing them to shift to a new place.
According to Science Alert, all the pertinent data was kept in the past 30 years which directly shows that three-quarters of the American trees in the variety of species are shifting to the west. The rate increased at around an estimated 15.4 kilometers per decade or equivalent of 9.5 miles.
The migration of American trees is an alarming condition for the shift could lead to the extinction of certain species of trees in selected forests, a new study has revealed. Now, there is a total of an average 20 miles north and 25 miles west trees which have moved due to climate change in the past 30 years.
The results of the study is a bit confusing for scientists, for they have long predicted that the climate change would send species of American trees toward the poles only. However, since the year 1980, more and more American trees from the east continue to move in the west and partly on the north. Although, the reason why a large number of American trees move to the west is still unknown.
Lead author of the study, Songlin Fei from Purdue University said that they have found out the stronger effects of precipitation on a forest in just the short term rather than temperatures. Besides, the eastern part of the US wherein more species of American trees are present started to become warmer in the last three decades, while the Southeast part becomes even drier.
