Fig 1.
Live- and dead-tree distribution across the burnt plot.
A) Distribution of live trees before the fire event. B) topographic map of the plot, with colours representing height gradient. C) Fire-severity rating per subplot, where High = Scorching >5 m height and/or crown damage, Moderate = Lack of understory and scorching up to 2 m, Low = Minor scorching on logs and lower trunk. D) Post fire distribution of dead trees. E) Enlarged fire severity map with number of eucalypt (E) and acacia (A) seedlings per subplot. The average number of eucalypt and acacia seedlings for each severity class were as follows- High: 111 and 7, Moderate: 71 and 6, Low: 75 and 3.

Spatial maps of Dicksonia antarctica and unburnt trees within the burnt site.
A) Map of burnt and unburnt D. antarctica clustering at the burnt site, B) Cluster map of unburnt D. antarctica and unburnt trees. Axes represent increments of 20 m, with the total plot size equal to 100 x 100 m (1 hectare). Clusters of unburnt D. antarctica are highlighted with circles.
Fig 3.
Graphical representation of the change in biotic and physical characteristics of the burnt site, compared with other wet sclerophyll sites across Tasmania.
Ordinations include A) species composition based on tree stems, B) species composition based on basal area, C) other site characteristics with fuels and D) other site characteristics without fuels. The burnt plot (pre and post fire) is circled in red. The black circle encompasses the burnt plot in relation to the reference unburnt plot. Ordinations were conducted using Bray-Curtis (dis)similarity matrices on square root transformed values.
