47. (Madison Square Park)

An artist transports several dozen dead or dying Atlantic white cedar trees from the Pine Barrens of New Jersey to Madison Square Park in Manhattan. Once easily found up and down the East Coast, these trees are now drastically reduced in number as a result of short-sighted forestry practices and sea-level rise and salt infiltration brought on by climate change. Borrowing a term commonly used for this phenomenon, which is becoming more and more widespread in coastal regions throughout the world, the artist titles her grove of desiccated trees Ghost Forest.
