Tree - new inhabitants of the Arctic!

The rise in temperature due to the warming of the earth caused the spruce forests to occupy the Arctic copper moss faster than the scientists imagined, chasing the creatures that only used to reside there.

Copper mosses are areas where trees are limited to growth by low temperatures and short growing seasons. In the Arctic, moss copper is dominated by permafrost. The only plant that can survive this harsh condition is grass, moss and lichen. Spruce forests are located near these mossy areas, and the border between them is called treeline.

In the summer, the permafrost layer dissolves, and copper moss begins to be covered by marshes and lakes, creating the only habitat for plants. However, climate change has extended warm summers and spurred tree growth, making the treeline deep into the moss.

When observing the tree cycle, researchers at the University of Alberta rebuilt 300 history of the position of treeline and tree density. The results showed that spruce was ingrained in the moss faster than their guess.

"It's like he waited until the right time and then decided to speed up and run, not just walk , " said author Ryan Danby.

While in many places, the more trees the better, this creates a danger for endemic North Pole species such as reindeer and sheep living on mosses, as well as indigenous peoples who depend on them. into these species to survive.
