The ANAE classification system adopts two sets of alternative water regime categories for lacustrine and palustrine aquatic ecosystems but does not propose a water regime category for marine or estuarine aquatic ecosystems (Appendix 2). The Victorian wetland inventory includes marine and estuarine as well as lacustrine and palustrine wetland systems. Therefore, water regime categories were designed to cover the full range of wetland system types. For lacustrine and palustrine wetlands the categorisation related to the level of permanency. For non-permanent (periodically inundated) lacustrine and palustrine wetlands, subcategories were defined (Table 22). These categories were the same as those adopted previously in a study by Cant et al. (2012). Estuarine and marine wetlands in Victoria were categorised by tidal regime (Table 22). Table . Water regime categories adopted in the Victorian wetland classification framework. Wetland system Water regime category Category description Water regime subcategory Subcategory description Frequency of inundation Duration of inundation Lacustrine and palustrine Permanent Inundated constantly, rarely drying completely - Constant, annual or less frequently but before usually wetland dries. Never dries or dries rarely (i.e. holds water at least 8 years in every 10), but levels may fluctuate within or between years. Periodically inundated Inundated annually to infrequently, holding water for at least 1 month to more than 1 year before drying Seasonal Annual or near annual inundation (i.e. holds water at least 8 years in every 10) Holds water 1-8 months, then dries Intermittent Infrequent – holds water, on average, 3-<8 years in every 10 Holds water > 1 month to > 1 year, then dries Episodic Infrequent – holds water, on average, less than 3 years in every 10 Holds water > 1 month to >1 year, then dries Unknown Water regime category unable to be determined Marine and estuarine Intertidal Inundated twice daily, with inundation lasting hours - - - Supratidal Inundated several times per year, with inundation lasting hours - - - Unknown Water regime category unable to be determined
