HSI Action Alert Support required for protection of essential marine habitat      


11th February 2014 - SYDNEY

A 2011 Humane Society International (HSI) nomination saw the “Posidonia australis complex sea-grass meadows” ecological community prioritised for assessment for an endangered listing under the Commonwealth Environment Protection and Biodiversity Conservation Act, 1999 (EPBC Act).  Three years on the Threatened Species Scientific Committee (TSSC) has released its draft description of the community, and the listing process has entered the crucial public comment period.

We kindly ask that you support HSI's efforts to protect this precious habitat by submitting a comment on the draft description of the Posidonia australis complex sea-grass meadows.


Click here to access the TSSC’s draft description and a copy of HSI’s original nomination, as well as further instructions and suggestions relating to the invitation to comment.

Lengthy submissions are by no means a requirement; a simple statement of your endorsement of the ecological community’s draft description assists in showing there is support behind giving Posidonia australis complex sea-grass meadows the recognition and legal protection it is eligible for and urgently requires through an EPBC Act listing.

Suggested points from the TSSC’s draft description and consultation guidelines that you may like to include:

  • The ecological community is highly productive and provides habitat, shelter and food for a diverse array of fauna permanently and temporarily inhabiting the ecological community.    
  • The sea-grass provides a stable substratum for the establishment of other plants and animals as epiphytes and epifauna, which in turn support higher food chains.    
  • The ecological community filters the water, removing and recycling nutrients, and stabilises sediment on the seabed, preventing large scale sand movement.    
  • The ecological community is an important carbon sink, capturing and storing carbon through photosynthesis and by trapping particles in the water column.    
  • The ecological community has declined due to increasing human pressures that physically damage sea-grasses and decrease water quality, reducing light available for sea-grass growth.
