A new study from North Carolina State University finds that greenhouse gas (GHG) emissions from standing dead trees in coastal wetland forests – colloquially (thông tục) called “tree farts” (cây đánh rắm) – need to be accounted for when assessing the environmental impact of so-called “ghost forests.”

In the study, researchers compared the quantity and type of GHG emissions from dead tree snags (gốc cây gãy ngang) to emissions from the soil. While snags did not release as much as the soils, they did increase GHG emissions of the overall ecosystem by about 25 percent. Researchers say the findings show snags are important for understanding the total environmental impact of the spread of dead trees in coastal wetlands, known as ghost forests, on GHG emissions.

“Even though these standing dead trees are not emitting as much as the soils, they’re still emitting something, and they definitely need to be accounted for,”
