“Grass that grows in seawater?”, Dalton Koss HQ is often asked. Yes, grass that can grow in and withstand seawater. But how?
Seagrass is similar to land-based grass, having leaves, veins and roots. The leaves grow from the base of the leave and reproduce with flowers and seeds. Many individual seagrass plants found growing together is termed a seagrass bed or seagrass meadow. Seagrass meadows can be found across the globe, usually in coastal areas close to shore where sunlight can penetrate the water column. Like all plants, seagrass needs sunlight to grow.
Although seagrass meadows may not look like much to the casual observer, they play an incredibly important role in supporting not only the health of our coasts and oceans, but also to humans. There are so many incredible facts about seagrass that DKHQ would like to share with you.
Did you know that seagrass meadows are nurseries for baby sea animals, providing shelter and protection from bigger animals and food to help them grow? Most of the fish we buy to eat would have spent some of their younger years living and growing in seagrass meadows before swimming to the oceans as adults.
Due to the amazing root network of seagrass, they are able trap and stabilise soft sediments, sand and other very small items floating in seawater. This means seagrass plays an important role in protecting our shorelines from erosion and helps improves seawater clarity.
In areas of seagrass meadows there are less toxic algal blooms. Seagrass is amazing at absorbing a whole lot of different nutrients, that often contribute to algal blooms, and using it as food to grow.
The seagrass plant is like a small cosmos to itself. It provides a solid surface for other small seaweeds, sponges and animals to grow.
Worried about high carbon levels in the atmosphere? Seagrass is able to absorb and store large quantities of carbon in their leaves and roots. Let’s protect seagrass so it can be a wonderful and natural way to address our high carbon lifestyles.
If you ever have an opportunity to snorkel in a grassy ocean meadow, do not pass it up! You might just be surprised with what you find.
