“…The result of significantly decreased δ 13 C in long unburnt trees of prescribed fire treatment at levels similar to that found in non water-limited irrigated Corymbia calophylla and E. marginata (−28.8‰ to −29.1‰) in Western Australia (Grigg et al 2009), may in part explain the empirical observation of reversed crown decline in E. delegatensis in response to understory/midstorey felling and prescribed fire (Ellis et al 1980). Particularly given that we have recently reported δ 13 C consistent with water limitation in E. delegatensis on sites with a history of long absence of fire (Close et al 2011).…”

“…Furthermore, recovery of premature decline in overstorey E. delegatensis forest has been reported in response to prescribed fire (Ellis et al 1980). We were interested in the ecophysiology associated with the premature decline of overstorey eucalypts with a history of a long absence of fire and how this might be affected by prescribed fire and understorey/midstorey removal (a proxy for mechanical thinning).…”

The objective of this study was to investigate how the management practices of prescribed fire and understorey vegetation removal affect water and nutrient relations of old, yet prematurely declining Eucalyptus gomphocephala. Long unburnt sites were established in Yalgorup National Park, Western Australia, adjacent to frequently burnt state forest sites. Trees were allocated to vegetation clearing, prescribed fire or no prescribed fire treatments. Prescribed fire was achieved in only one long unburnt national park site so that the results were pseudoreplicated but analysed accordingly. Soil chemistry, plant nutrient availability and tree foliar carbon and nitrogen isotope ratio and nutrient concentration were investigated. No effects of vegetation clearing were found. Prescribed fire sites were associated with sky exposure and bare ground whereas no prescribed fire sites were associated with shrub and litter cover and litter depth. Foliar carbon isotope ratios were significantly more negative in prescribed fire, relative to no prescribed fire, treatments on long unburnt sites. Soil exchangeable Zn and Mn and plant available (estimated by charged resin beads) Mg were higher on prescribed fire, relative to no prescribed fire, long unburnt sites. Seedling bioassays indicated elevated P and Cu availability on prescribed fire, relative to no prescribed fire, treatments. In overstorey E. gomphocephala, foliar N levels were elevated (but not to excessive levels), and there was a trend toward elevated foliar Mn, in prescribed fire relative to no prescribed fire treatments on long unburnt sites. In the context of our large-scale pseudoreplicated case study, prescribed fire provided a pulse of water and N, (with some indications towards provision of elevated Mn, Cu and Mg) availability to E. gomphocephala in decline on sites with a history of a long absence of fire that may in part underpin observations of elevated tree health on sites that have a history of relatively frequent fire.

“…Bowling and McLeod (1968) found that burnt stands were less affected by 'regrowth dieback' than unburnt stands. 'High altitude dieback' is a consequence of fire exclusion, and can be remedied by felling and burning understoreys (Ellis et al, 1980;Ellis and Pennington, 1992). Farr et al (2004) found some evidence that prescribed burning moderated outbreaks of gumleaf skeletoniser (Uraba lugens) in the southern jarrah forests.…”

“…The roots and mycorhizzae degenerate, and the canopy thins but there are no root rot fungi or gregarious folivores adapted to the cool environment (Ellis et al, 1980;Ellis and Pennington, 1992). Native understorey plants respond to the changes in the soil and the microclimate under the reduced canopy (Ellis and Pennington, 1992).…”

Wet‐sclerophyll forests are unique ecosystems that can transition to dry‐sclerophyll forests or to rainforests. Understanding of the dynamics of these forests for conservation is limited. We evaluated the long‐term succession of wet‐sclerophyll forest on World Heritage listed K'gari (Fraser Island)—the world's largest sand island. We recorded the presence and growth of tree species in three 0.4 hectare plots that had been subjected to selective logging, fire, and cyclone disturbance over 65 years, from 1952 to 2017. Irrespective of disturbance regimes, which varied between plots, rainforest trees recruited at much faster rates than the dominant wet‐sclerophyll forest trees, narrowly endemic species Syncarpia hillii and more common Lophostemon confertus. Syncarpia hillii did not recruit at the plot with the least disturbance and recruited only in low numbers at plots with more prominent disturbance regimes in the ≥10 cm at breast height size. Lophostemon confertus recruited at all plots but in much lower numbers than rainforest trees. Only five L. confertus were detected in the smallest size class (<10 cm diameter) in the 2017 survey. Overall, we find evidence that more pronounced disturbance regimes than those that have occurred over the past 65 years may be required to conserve this wet‐sclerophyll forest, as without intervention, transition to rainforest is a likely trajectory. Fire and other management tools should therefore be explored, in collaboration with Indigenous landowners, to ensure conservation of this wet‐sclerophyll forest.
