Threatened ecological communities


As described, three ecological communities that occur within the AMLR region are nationally listed as critically endangered. For the Swamps of the Fleurieu Peninsula, formal recovery planning and management has been underway since 2003 (though for several years prior the Fleurieu Peninsula wetlands have been the focus of management as part of the southern emu-wren recovery program). Initial recovery planning processes have also commenced for the recently EPBC-listed peppermint box grassy woodlands and iron-grass grasslands communities. Currently a nomination for EPBC listing of grey box woodland (threatened within AMLR) is being considered.

The assessment undertaken to identify and prioritise specific threatened ecological communities within AMLR highlights many priority communities that are not currently being targeted as part of any formal recovery program (). Other than EPBC-listed ecological communities, priority threatened communities in AMLR include:



  • Banksia marginata grassy low woodland (Very High priority)

  • Eucalyptus microcarpa grassy low woodland (Very High priority)

  • Eucalyptus dalrympleana ssp. dalrympleana open forest (Very High priority)

  • Themeda triandra +/- Danthonia spp. tussock grassland (Very High priority)

  • Callitris preissii +/- Eucalyptus leucoxylon grassy low woodland (High priority)

  • Gahnia filum sedgeland (High priority)

  • Eucalyptus ovata +/- E. viminalis ssp. cygnetensis +/- E. camaldulensis var. camaldulensis/ Low woodland (High priority), and

  • Eucalyptus fasciculosa +/- E. leucoxylon heathy woodland (High priority)
