Coastal Habitat Lecture: Seagrass and Coral Reefs

A set of flashcards based on lecture notes focusing on coastal habitats, particularly seagrass and coral reefs.

What are the primary habitats discussed in this lecture?

Seagrass and coral reef habitats.

Why is seagrass important for coastal ecosystems?

It holds fast the sand, preventing erosion and protecting land masses from waves.

What environmental factor is crucial for the growth of seagrasses?

Light; they require a lot of light to grow.

What is the seagrass depth range used to assess water quality?

The deepest and shallowest extent of seagrass at different sites is measured annually.

How do seagrasses contribute to carbon storage compared to forests?

Seagrasses store carbon at rates that are 40 times better than forests, despite covering only a small area.

What are the root systems of seagrasses similar to?

They have a root system similar to the grass found in yards.

Name two animals that depend on seagrasses for food.

Dugongs and green turtles.

What role do macroalgae play in coral reef ecosystems?

They serve as a food source and habitat for protection and shading.

Which specific seagrass species were highlighted in the lecture?

Halophila, Posidonia, and Cymodocea.

What is one method used for monitoring seagrass in Moreton Bay?

Photo quadrats and citizen science initiatives.
