The forest fire recovering of the boreal forests, which are stunted by wood strikes and heavy fire

More carbon is stored in boreal forests than any other kind of forest, but that changes with more and more frequent and heavy forest fires.

More than four years after a forest fire had burned more than ten times the annual property of Land in Sweden, a group of researchers recently found that a burned Boreal forest floor has not yet been recovered. The vegetation within the slowly growing forests had not shown any signs of a recovery, partly due to dismantling and carbon exemptions or the soil breathing in the soil of the forest, which was significantly influenced by average fire.

“Since the breathing of the forest floor is closely linked to tree root activity, it will probably take many years before it reaches the values ​​observed at an unbroken control stand,” said the researchers in their recently published publications Agricultural and Forest meteorology journal Paper.

The researchers confirmed that a decline in carbon exemptions from soil can sound positive in the context of the global gas-gas-gas gas gas climate change, but the fact is missing for the trees. In reality, a lack of soil breathing means less trees and other vegetation grow and turns a once carbon dress into a long -term carbon emitter.

The researchers said which trees were recorded after the fire had also played a major role in the recovery of the forest. The logging of living trees after a low -fire fire led to “immediate and significant” decreases of the soil breathing, while the rescue of dead trees significantly slowed down the subsequent vegetation after a high fire of the high value.

“Our results underline the considerable and persistent changes in the carbon flows of the forest floor due to the fire and selection of the strategy according to the management,” says the paper. “Future work is necessary to examine the interaction effect between the severity of the fire and the recovery of the salvage and to examine the effects of various location preparation methods on the carbon flows after the fire and recovery of vegetation in the boreal context.”
