2009) reported that mortality rates for Livistona spp. were among the lowest for all plant forms in unburnt areas, as well as locations with early dry season and late dry season ﬁres. It appears that L. humilis is most susceptible to ﬁre immediately after the wet season growth period, when leaf tissues have yet to become ligniﬁed enough to An array of responses to ﬁre has been recorded for Livistona species, and although only a few species have been studied some generalisations can be made. Fire intensity and season appear to be the dominant factors affecting survival and/or damage to palms in tropical savannas and woodlands (Werner 2005).
No genera are shared with New Caledonia, although close supra-generic relationships exist. Tectonic movement, the time of separation and movement of landmasses and the creation of land through volcanism helps to explain much of the context of the distribution patterns of many elements in the Australian palm ﬂora.
