Eelgrass Meadow along eastern shore of Bellingham Bay

This diary is about the wonders of eelgrass, one of the major components of near shore habitat that nurtures a myriad of sea critters. Additionally it provides many other functions in support of our sea life, our recreation, and it even contributes to reducing the CO2 problems in our oceans and atmosphere. There are other sea grasses and kelps that contribute as well, but I think that eelgrass is a star.

Eelgrass is a common name for a species of seagrasses.  I will focus on the salt water variety of Zostera marina and describe its vital ecological functions, its current status, and efforts to sustain it. This form of eelgrass is the most widely distributed aquatic flowering perennial in the northern hemisphere, growing largely in the cooler waters of the northern Atlantic and Pacific oceans.

I will in part highlight eelgrass in Puget Sound, the southernmost part of the Salish Sea which is the second largest estuary in the US (by volume). However, most of what applies to our local intertidal waters also applies to eelgrass beds and other seagrasses elsewhere in the Salish Sea, along the shores of Oregon and California, the western Atlantic Seaboard and near shore habitats globally.

This is the first of a two part post. In this first part, I describe the many gifts it gives us. In Part 2, I describe its current status, take a look at its threats and the efforts underway to preserve this valuable resource.
