Trees are dying along the US coastal areas. This can happen on totally protected forest land. The salt water water table is creeping inland and rising towards the surface. The salinity along with drought, disease, insects, unfriendly weather patterns are causing the trees to die in clusters. In some places the trees are more than a kilometer from the coast.

There is no way of stopping the salt water from reaching the roots.
Because they die in clusters, old or young, it creates a section of forest composed of dead trees, which accounts for the term, ghost forests.

It is more noticeable in some areas than other areas. This could be caused by the physical makeup of the land underneath the trees. The way the ocean waters permeate the underground land is poorly understood. Besides the trees, the ecology of the entire area is changing Studying the bacteria in the soil provides information about the salinity of the soil.

One of the confusing aspects of global change is that not everything changes at the same rate. Some areas change at a much faster rate than other areas. Some areas have experienced no real noticeable changes at the superficial level, but in the unseen interactive zones, changes are happening. In North Carolina, for unexplained reasons, the trees are dying in coastal areas at greater rates than elsewhere.

So far, the areas turn into swamps with dead vegetation. This could eventually turn the land into tidal wetlands.

I have read that with the damming of major rivers, and abstraction of water from them, the land downstream is being robbed of both silt and water. So the land of the Carolinas is losing ground to the sea. The sea is rising due to glacier runoff and to increased temperature, which makes the same amount of water expand, as we have discussed elsewhere. This probably plays a part in the salt water table strengthening.
