List of threatened ecological communities of Australia  This list of threatened ecological communities of Australia is derived from the Australian federal government's assessment of submissions regarding ecological communities, assemblages of flora and fauna with identified interactions in particular habitats, with determinations on their conservation status and level of protection under the "Environment Protection and Biodiversity Conservation Act 1999". Their status as threatened ecological communities (TEC) is noted as meeting the criteria as critically endangered, endangered, or vulnerable, and where a revision has resulted in delisting or ineligibility.
