Exploring the Secrets of New York's Disappearing Wetlands
Wetlands can store up to 50 times more carbon than forests, protect coastal communities from storm surge, and are home to countless rare plant and animal species. Wetlands are also endangered, threatened by rising seas and human development. At one time, vast wetlands comprised much of what is now New York City, but today only remnants remain.
Botanist and climate scientist Dorothy Peteet has been studying wetlands for more than 40 years. Now, she's investigating how much carbon is stored in their sediments as part of a national effort to prioritize marshes for preservation.
Read more about Dorothy's work, and watch her explain why marshes must be preserved in the first installment of our new Science for the Planet video series.
