Critical component Vegetation types Critical service: Natural or wetland ecosystem Thirteen different Tasmanian wetland vegetation communities were identified within ECCBIL which corresponds to six TASVEG communities. Sixteen flora species have been recorded on site that are threatened in Tasmania. Vegetation succession is an integral component of the ECCBIL wetlands such that some changes in vegetation communities are normal. Maintenance of the extant TASVEG vegetation communities on site at time of listing i.e. lacustrine herbland (AHL) freshwater aquatic sedgeland and rushland (ASF) freshwater aquatic herbland (AHF) saline aquatic herbland (AHS) saline (ARS) succulent saline herbland (ASS). Based on the limited available vegetation data i.e. TASVEG mapping, the Kirkpatrick and Harwood (1981) survey and expert opinion. Low: Not confident in the data and not confident that this will represent a change in ecological character. Limited information about the variability in extent and condition of the vegetation types since the time of listing is available.
