Bay grass restoration threatened by warming, scientists say

The Bay region is unlikely to meet its underwater grass restoration goals unless it clears up the Chesapeake’s water beyond what is now targeted, scientists warned in a recent journal article.

If more action is not taken, they warn that eelgrass — the primary underwater grass species found in high-salinity portions of the Bay — may face a “catastrophic” decline in the Chesapeake because of a combination of warming temperatures and murky water.

As a consequence, they predict populations of blue crabs and many other fish will also decline as areas with once-lush grass beds convert to muddy bottoms. They project that the resulting economic impacts from that loss of habitat could reach $1.5 billion to $2.5 billion annually.

About Wildlife + Habitat

The Chesapeake Bay region supports more than 2,700 species of plants and animals, including 348 species of finfish and 173 species of shellfish.

It is also home to at least 29 species of waterfowl. Nearly one million waterfowl winter on the Bay – approximately one-third of the Atlantic coast’s migratory population. The birds stop to feed and rest on the Bay during their annual migration along the Atlantic Flyway.

Nearly 80,000 acres of bay grasses grow in the shallows of the Bay and its tributaries. Young and molting blue crabs rely on bay grass beds for protection from predators.
