Seagrass
- Seagrasses grow in bays, estuaries and coastal waters.
- Occur below the high tide line in sheltered, shallow waters.
- Due to their need for sunlight for photosynthesis, they are usually found in less than 2 metres water depth.
- Strap-like leaves or paired oval leaves
- Grow from rhizomes - underground stems.

Seagrasses - Ecological Services
- Seagrasses are important fish habitats.
- Juvenile fish settle in the seagrass for both food and protection.
- Different parts of the seagrass - leaves, stems roots host epiphytes and microorganisms.
- The rocks, sand and gravel that seagrasses grow in, provide a home for invertebrates and microorganisms.

Seagrass-Watch - Global Seagrass Observing System
If you would like to take part in an organised program, you may like to have a look at Seagrass-Watch. Seagrass-Watch is a not-for-profit organisation, and one of the largest long-term seagrass observing networks globally.
Seagrass-Watch is highly recognised for its scientific rigour, and more than 25 countries participate in the Global Seagrass Observing Network (GSON), monitoring & researching the status and trends in seagrass condition.
Their website provides an overview of sampling methods and students can examine data from the other sites from around the world.
