The Tamoyo Maiden, a ship out of the Philippines, recently delivered sugar from Mexico to the Domino Sugar refinery in Baltimore, Maryland. Travelling around the globe, taking on and discharging ballast water from faraway ports, ships like the Tamoyo have the potential to bring non-native species into Bay waters. Laws and regulations, enforced by the U.S. Coast Guard, are in place to make sure they don't. But ballast water exchange can put ships in danger, and may not kill all the hithchiking species. Could new technology that does not require ballast water exchange better prevent species invasions and keep ships at sea safer?  more . . .

Skeptics question whether an invasive species has ever really caused significant ecological damage in the Bay. The answer, this article says, is yes.  more . . .

Scientists visiting from Florida in the early 1980s identified an invasive grass species growing in Constitution Lake on the National Mall. How did it get there? And how did it spread to the Potomac River?  more . . .

Invasive species get to the Bay in a variety of ways. Once here, their effects can be devastating.  more . . .

Restoration Takes Root: Living Shorelines for Changing Coasts

June 2025 • Volume 24 Number 1

Roots at the Water’s Edge

By Ashley Goetz

As erosion threatens treasured places around the Chesapeake Bay, communities are turning to nature-based solutions. Explore how living shorelines are helping to protect coasts and heritage on opposite shores of the Bay.

Seeding Shorelines

By Madeleine Jepsen

Living shoreline plants have a tough job: they must hold down the sandy shoreline with their roots and ease waves with their stems, all while surviving salty water. 

 

Designing with Nature

By Madeleine Jepsen

Researchers are on a mission to determine which key components make a living shoreline successful at preventing erosion—but first they must gather crucial data. 

 

Living Rocks for Living Shorelines

By Madeleine Jepsen

Oyster biology is both an obstacle and an opportunity when it comes to living shorelines. Learn how and why oysters are sometimes included in living shoreline projects. 

 

A Marsh Grows in Brooklyn

By Ashley Goetz

A living shoreline is under construction in Baltimore City—part of a sweeping project that aims to restore more than 50 acres of habitat along 11 miles of shoreline.
