NJ.com reports that salt water intrusion is causing clusters of trees in New Jersey to die off. The rising of sea levels related to climate change appears to be the root of that demise. Williams, with Pine Creek Forestry, tells NJ.com that roughly 90 percent of Atlantic White Cedars have been lost since colonial settlement because of storms and storm surge. Williams, who's examined forestation all over the world, says stagnant salt water kills the cedar trees. The once thriving Atlantic White's are now stark and barren forming what conservationists call 'ghost forests'.
