Eucalyptus spathulata (Swamp Mallet) Woodland
See the report by Harvey and Keighery for sub-communities recognised by Keighery (Appendix 1), Gibson et al. (Appendix 2) and Griffin (Appendix 3). Many of these correspond to the sub-communities presented here, as is shown in the right hand columns of the tables in the appendices, but there are some unusual groups that are not recognised in this classification.
