Exploring the Secret Gardens of Seagrass

Updated: Mar 6

As we delve deeper into understanding the intricate ecosystems that sustain life on our

planet, one often overlooked hero emerges from the depths: seagrass. With World

Seagrass Day fast approaching on March 1st, it's the perfect time to shed light on this

under-appreciated marine marvel and recognise its crucial role in our environment.



Seagrass may seem inconspicuous at first glance, resembling nothing more than a

simple underwater plant. However, its significance cannot be overstated. These

flowering plants (they are not seaweed) form dense underwater meadows along

coastlines across the globe, acting as vital ecosystems for a myriad of marine life.

Seagrass meadows fringe the shores and the depths of Pumicestone Passage.


Beneath the swaying blades of seagrass, a bustling community thrives. From tiny

invertebrates to large marine mammals, such as the elusive Dugong. countless species

rely on these habitats for food, shelter, and breeding grounds. Juvenile fish seek refuge

in the intricate root systems, while crustaceans scuttle among the leaves, forming the

base of complex food webs.


In addition to supporting marine life, seagrass meadows play a crucial role in mitigating

climate change. They are among the most efficient ecosystems for carbon sequestration, storing vast amounts of carbon in their soils. They are an invaluable ally

in the fight against rising CO2 levels and ocean acidification.





Beyond their ecological significance, seagrass meadows offer tangible benefits to

coastal communities. Their extensive root systems help stabilize sediments, reducing

coastal erosion and buffering the impacts of storms and waves. Furthermore, they act as

natural water filters, improving water clarity and quality.


Despite their importance, seagrass meadows face numerous threats, including coastal

development, pollution, and climate change. As we observe World Seagrass Day on

March 1st, it's crucial to raise awareness about the plight of these ecosystems and take

action to protect and restore them.


How you can help

Things we can all do to protect seagrass:

  1. Support conservation efforts by getting involved with BIEPA’s local citizen science projects, like Dugong Diaries and Bribie Island BioBlitz.

  2. Contribute to a global seagrass citizen science project by downloading the Seagrass Spotter app (find on Apple App Store or Google Play Store) and start snapping and sharing photos.

  3. Practice responsible boating and fishing by minimising your impact on seagrass habitats. Follow boating regulations, use sustainable fishing practices and avoid anchoring in areas of seagrass meadows.

  4. Take steps to reduce your carbon footprint and minimise pollution to help mitigate the impacts of climate change and water pollution on seagrass ecosystems.


As we celebrate World Seagrass Day, let's not only appreciate the beauty and diversity of these underwater meadows, but also commit to protecting and preserving them for

generations to come. After all, the health of our oceans, and indeed our planet, depends

on it.
