Seaside Sustainability collaborates with local, regional, and national partners to work on projects in the area of marine sciences. 

Seaside Sustainability partnerships monitor the invasive species in and around the coastline of Cape Ann and beyond. This work is responsible for the mitigation of Green Crabs, Asian Shore Crabs, Pepperweed, Phragmites, and many more invasive species, with a common goal to restore the coastlines and highlight the diversity of the marsh.


Phragmites Australis


Phragmites Australis is a non-native grass that is present along the marsh of the North Shore. These plants will often grow very densely, blocking out sunlight that promotes the growth of native species. As these plants continue to be a problem, Seaside Sustainability is monitoring their populations on the North Shore to experiment with organic alternatives to the current methods of eradication. This initiative is used as a means of restoring the marsh, organically, safely, and responsibly. 


Green & Asian Shore Crab


As invasive species, it is important to measure the effects that the rise in this crab's population has on other marine animals. To conduct this study, Seaside Sustainability has set traps off the waters of the North Shore that are monitored periodically; where they record the number of crabs that are present in the water. This program also offers a chance for a sustainable economy by providing businesses with Green Crabs that they can use as a menu item, for a sustainable and local meal.



Every Spring and Summer, Seaside Sustainability partners with a local Audubon official, Liz Duff. This group survey’s islands and beaches around the North Shore to map and mitigate the invasive perennial known as Pepperweed. To engage youth in citizen science, Liz’s students join us to map the coast from Essex to Marblehead, ensuring the Pepperweed population is under control. Through these efforts, we strongly believe that the marsh can be restored.
