What is causing the formation of ghost forests in North Carolina?

Researchers have found that dredging activities dating back to the late 1800s, not just climate change, are a major driver behind the formation of ghost forests in North Carolina's coastal regions.

How do dredging activities impact the bald cypress trees in North Carolina's wetlands?

Dredging has caused saltwater intrusion into the freshwater wetlands, stressing and killing countless bald cypress trees that are adapted to low salinity levels.

What are the consequences of losing bald cypress trees in North Carolina's coastal wetlands?

The decline of bald cypress trees can hinder the wetland's ability to control floods and filter water, potentially impacting surrounding communities and economies that rely on these crucial ecosystems.

Dredging Drives Rapid Transformation of North Carolina's Coastal Forests

In 2025, researchers in North Carolina have uncovered a surprising cause behind the formation of "ghost forests" in the state's coastal regions. While climate change and sea-level rise are often blamed for the eerie phenomenon, a team from the University of North Carolina Wilmington has found that dredging activities dating back to the late 1800s are a major culprit.
