World Seagrass Day Hero

Dr. Susan Williams

Dr. Susan Williams (1951-2018) was a pioneering marine ecologist and professor at the University of California, Davis. Her extensive research focused on the ecology and conservation of seagrass ecosystems, particularly in the Pacific Ocean. She was a leading voice in understanding the impacts of climate change and pollution on these vital habitats, advocating for their protection and restoration throughout her career.

History of World Seagrass Day

Seagrass serves an important role in maintaining the marine ecosystem. Except for Antarctica, various types of seagrass are found on coastlines around the world. From the common eelgrass, shoal grass, star grass, and the like, seagrass provides an important source of food for marine life. It also supplies crucial environmental, social, and economic benefits.

Seagrass evolved around 100 million years ago when most plant life was still found underwater. Over the course of its evolution, it has adapted to living and reproducing in various marine environments, bending and swaying with currents and dispersing its pollen through the water.

Fish, turtles, manatees, plankton, and even sharks get their sustenance from seagrass, among other things. Seagrass also acts as nursery habitats for commercially harvested fish and helps improve the water quality of the environment it inhabits. There are currently 72 recorded types of seagrass in the world, covering an area of around 300,000 square kilometers in 159 countries.

Seagrass sediments contain between 4,200 and 8,400 Tg of organic carbon, which is nearly twice the amount of carbon per area compared with land soil. With the advent and ongoing process of climate change, seagrass’ role as a carbon deposit is much more crucial today, to help sustain sea life and its ecosystem. For one, it stores up to 18% of the world’s oceanic carbon, which is greater than the percentage stored by rainforests. This function makes it a key influence in battling the effects of climate change.

As with most marine resources, seagrass is currently under threat by human activity. A United Nations report stated that up to 7% of seagrass marine habitats are being wiped out worldwide every year; this is equivalent to a football field of seagrass lost every 30 minutes.

This emergency compelled the United Nations, following a resolution by Sri Lanka, to declare a formal World Seagrass Day, to raise awareness on preserving and conserving seagrass around the world. The commemoration was formally announced in 2022.

100 Million Years Ago
Seagrass’ Evolution Begins

Seagrass begins to evolve from terrestrial plants.

1930s
A Disease Ravages

Up to 90% of all eelgrass in temperate North America is wiped out after succumbing to a mold-like disease, causing the extinction of a type of sea snail.

2014
Restoration Efforts Succeed

Around 7.65 million seagrass seeds are planted along the coast of Virginia, U.S., resulting in the growth of up to 6,195 acres in one of the most successful seagrass restoration efforts.

2022
World Seagrass Day is Initiated

The United Nations declares March 1 as World Seagrass Day.

How Businesses Can Celebrate World Seagrass Day

Restaurants can highlight sustainable seafood options sourced from healthy marine environments. Dive shops and tour operators can offer educational excursions focused on seagrass meadows. Retailers can partner with local conservation groups, donating a portion of sales or hosting awareness events to educate customers about the ecological importance of seagrass.

World Seagrass Day FAQs

When is World Seagrass Day?

In 2027, World Seagrass Day will be observed on Monday, March 1. This fixed date provides a consistent opportunity each year to spotlight the critical role of seagrass meadows.

Why is seagrass important?

Beyond supporting biodiversity, seagrass plays a vital role in stabilizing coastlines and protecting against erosion, especially during storms. These underwater ecosystems are also highly effective at sequestering carbon, making them a key natural solution in the fight against climate change.

Where are seagrass meadows found?

From the warm waters of the Caribbean to the cooler seas of Northern Europe, seagrass species have adapted to a wide range of marine environments. They are particularly abundant in tropical and subtropical regions, but also extend into temperate zones globally.

What threatens seagrass ecosystems?

The cumulative impacts of boating activity, unsustainable fishing practices, and rising ocean temperatures also contribute significantly to seagrass degradation. Conservation efforts worldwide are focused on mitigating these threats through policy, restoration, and public awareness.

How to Observe World Seagrass Day

  1. Read about seagrass

    What better way to learn about seagrass, its role, and its plight than to read a material written by the experts? Read articles, books, and reports by marine scientists, conservation foundations, and similar institutions to broaden your knowledge of seagrass.

  2. Support seagrass charities

    Support and/or donate to seagrass conservation efforts worldwide. These include such organizations as Project Seagrass and The Ocean Foundation’s SeaGrass Grow program. Your support makes all the difference.

  3. Visit the shore

    Travel to the coast and bask in the seagrass-covered waters. Hang out at the beach, swim in the ocean, and see what kinds of seagrass are there. After all, seagrass helps make the view picturesque and natural.

5 Important Facts About Seagrass

  1. Millions depend on seagrass underwater

    Seagrass provides a habitat and food for almost 70% of all sea life, from manatees and sea turtles to shellfish and plankton.

  2. An effective carbon absorber

    Seagrass is able to absorb carbon up to 35x faster than the Amazon Rainforest.

  3. The sun gives life to all

    Like all grassy plants, seagrass needs an ample amount of sunlight to survive, thus making it most visible in sunnier climates and greater depths.

  4. The efficacy of seagrass

    A football field’s worth of seagrass is able to absorb 7,500 miles worth of automobile pollutants and treat sewage from 780 people.

  5. An emergency situation

    At least 35% of seagrass worldwide has been lost or degraded in the past 40 years, further accentuating the need for conservation.

Why World Seagrass Day is Important

  1. Seagrass keeps the world running

    Seagrass plays an important role in maintaining both marine and human ecosystems. Its function as a carbon sink helps absorb carbon particles from the surface and from the sea, which helps improve the quality of the water and lives of those who live around it.

  2. Seagrass is reliable

    Aside from its environmental benefits, seagrass also contributes to the economy. Businesses that rely on seagrass for their work benefit from its abundance and quality. Fish that are caught in seagrass-rich environments tend to be healthier.

  3. It spares us the thought of environmental dysfunction

    Without seagrass, what would our seas look like? They would be desolate, for sure, which would affect every living thing on the planet.
