Recent visitors may have seen a green covering on Model Yacht Pond in Centennial Park – a cause for concern? Not necessarily. In fact, it may be helping!

A park visitor sent this photo to us to ask about whether it was something to be worried about:

What is the ‘green covering’?

The green growth on Model Yacht Pond is a dense growth of aquatic plants called Duckweed.

Duckweeds are native to Australia and include the smallest flowering plants on Earth. They can form a dense green mat on the water surface in nutrient-rich conditions.

They are an important food source for birds and aquatic animals – in fact, it has recently been the source of research into whether it could be used as an animal “superfood”!

So, while it looks odd, the Duckweed is possibly doing a good job removing some of the excess nutrients in the pond.
