Climate Change Causes Growth in Old Trees

The old trees in China have experienced spurt growth in recent years due to the warming climate. The growth is good in the short term, but how can it affect the forests in the long run?

Trees Growth Spurt

Climate change affects the planet in many different ways, and trees are no less affected than other living creatures in the planet. In a new study, researchers describe just as the warming planet can be affecting trees and how the effect could be horrible for forests in the long run.

For the new study, researchers have looked at the trees of Dahurian Larch in the north-eastern forests of China and found that trees grew more than in 2005 and 2014, as in the 40s. What's more, they found that the older trees are more sensitive to the effects of the younger trees. For example, these 400-year-old trees grew more in the decade than in 300 years earlier.

This is quite unusual because Dahurian larch trees typically slow down at 150 years of age, and almost stop at 300 years of age.

According to the researchers, it is possible that the warmer soil temperature is driving the growth rate, as it slows down the permafrost layer depth. When this happens, these trees can grow deeper and therefore feed more nutrients from the soil.

Forest Disaster

While fast growth seems like a good thing for the trees, it can actually be disastrous for forests in the long run. This is because the temperature continues to warm and the permafrost continues to melt, which will soon not support the growth of the trees, and may even cause the forest to decay.

Since Dahurian Larch is the only tree species that can survive the frightened permafrost of Russia, Mongolia, and northern China, losing the trees would completely change the ecosystem. What's more, this thaw is a problem that has occurred in permafrost regions in different parts of the world.

"If the area of ​​forest retreat in this area is in the future, it is also not a good sign for the entire Border Forest," said Xianliang Zhang of the Shenyang Agricultural University in China, lead author of the study.

The study is published in this Geophysical Research Journal: Biosciences.
