Taxonomy and indigenous range follows the New Zealand Plant Conservation Network (see: http://www.nzpcn.org.nz). Flammability category determined by Wyse and others (2016).
^aWyse and others (2016) collected these samples prior to recent taxonomic revision of the K. ericoides species complex (de Lange 2014), and as such they were referred to under the previous nomenclature (Kunzea ericoides (A.Rich) Joy Thomps.). We cannot determine if this was the same, or a different species to that burned in the present study; however, K. robusta is the most abundant and widespread of the revised taxa.
