Underwater Grasses

The Chesapeake Bay’s grass beds, once devastated, are making a comeback.

A study published this week in the Proceedings of the National Academy has documented a three-fold increase in the amount of bay bottom and its tributaries covered by the beds.

It’s gone from 7,000 hectares of grass in 1984 to about 25,000 hectares now, said Jonathan Lefcheck, the lead author of the study. That’s enough grass to cover New York City’s Central Park three times over.
