What do we mean by 'freshwater'? We have used a very broad definition of 'freshwater', essentially equating it with 'non-marine'. The marine environment is considered to be those areas influenced by the sea, i.e. under marine tidal influence. There are some intermediate habitats and we have used our discretion in such cases. Sometimes there is insufficient information provided to determine the habitat. The widespread occurrence of saline and hypersaline lakes in Australia means that brackish and marine taxa may be found far inland. Once again we have used our discretion as to whether we include taxa or not (e.g. algae reported from Lake Wellington in Victoria have not been included since it is usually an estuarine lake that sometimes becomes almost fresh due to flood waters). The designation '?non-marine' has been used when we could not determine whether the habitat was non-marine or marine, but seemed to be the former. |
