We surveyed each site in a location representative of the
wetland (Higgins et al., 1997) using a cross-sectional transect from
the western edge to the lowest point. All transects were located at
least 50 mfromany road or other obstruction. Along each transect,
we surveyed three 2×2 m plots (edge, intermediate and lowest
point) but three sites were too narrow to sample three plots and we
sampled one plot at one site and two plots at the other two sites
(total number of plots=68).
Within each plot, we estimated the cover-abundance of each
species using the Braun-Blanquet scale (Werger, 1974). We
allocated a B-B value of 1 to specieswith a cover of less than 5%as
well as species that were observed only outside the plot, within
1–2 mof its periphery.We also noted the maximumheight of each
species, its reproductive state (i.e. flowering, fruiting), and its
post-fire reproductive mode (i.e. resprouter, reseeder). We also
noted the percentage of bare ground and, as an indication of
senescence, the cover of dead plant material. Nomenclature
