Posidonia australis meadows have experienced large reductions in distribution across six NSW estuaries since the mid-1900s. It is at risk of becoming locally extinct in some estuaries due to on-going impacts. 

What did we use before "single use" became ingrained in our everyday lives? The organising committee for the national AMSA 2019 conference held in Fremantle this week wanted to eliminate plastic. Here's how that went...

The June 2019 edition of the Australian Association for Environmental Education OZEEnews features an article by Angela Rossen on her biodiversity outreach work.

Seagrasses are clonal plants and therefore may persist for a long time. They are among some of the oldest plants on earth, with some clones thought to be thousands of years old. However, renewal, or the recruitment of new genetic individuals, also occurs in clonal species. This tends to be sporadic and patchy, but can be very difficult to quantify.

Healthy seagrass meadows play a big part in making some of the inshore and sheltered water fishing in WA so good. In fact, research has suggested 400 square meters of seagrass can support up to 2000 tonnes of fish a year! The total number and diversity of fish is limited by the amount of habitat available to them.

Renown for its extreme tides, the waters of the Kimberley host seagrasses and macroalgae that thrive against the odds. A three-year study combined science and traditional knowledge to uncover some of the secrets of these fascinating species, and the herbivores that feed on them.

If we are to protect and conserve nature let us begin by discovering it for its own sake and marveling at its beauty and complexity.

Western Australia’s vast meadows of Posidonia australis seagrass are amazingly productive with massive flowering events annually in the cool winter waters. Constantly moving water presents challenges for effective underwater pollination, but seagrasses have evolved special traits to adapt to these difficulties.

Seagrasses are marine flowering plants, with Western Australia being home to more species than any other place on earth. However, seagrass meadows here, and elsewhere, are rapidly diminishing due to human impacts, and research is focusing on understanding genetic patterns and their ecological drivers.

Seagrasses belong to a large group of marine flowering plants, adapted for an entirely submerged life. Just like flowering plants on the land, they produce flowers and seeds, but with pollen and seed dispersal through the water column. Seagrasses also exhibit extensive vegetative (or clonal) reproduction through rhizomes.
