“…While the natural values (physical and ecological landscape) of the island are recognised through WH listing, the island's sociocultural values are acknowledged only informally (Lennon 2012). UNESCO guidelines outline the characteristics of a cultural landscape as: 'the "combined works of nature and man" …illustrative of the evolution of human society and settlement over time, under the influence of the physical constraints and/or opportunities presented by their natural environment' [in Lennon 2012: Annex 3, UNESCO Operational Guidelines for the Implementation of the World Heritage Convention (Geneva: UNESCO, 2008), p. 83)].…”

“…The definition acknowledges that cultural landscapes result from cultural values developed as a result of 'deep social attachments to the place' (p. 30). These attachments are associations with the natural landscape rather than specific material cultural artefacts (Lennon 2012). Protecting the functions and processes of natural environments depends on the perception and representation of the divide between nature and culture (Hytten 2009;Quiroga 2009).…”

“…From 13,300 to 2190 cal yrs BP micro and macro charcoal levels remain fairly constant. Micro charcoal peaks suddenly at 25 cm, with macro charcoal peaking at 26 cm, both peaks coincide with the possible arrival and settlement of Europeans on the Island in 1840's (Lennon 2012), when charcoal deposits increase due to possible land clearing and modification of the landscape (Stewart and Moss 2015). However the quantity of charcoal has no clear correlation to either size or frequency of fire but may reflect fuel, for example dry timber may proceed to ash while moist grass may produce copious char particles.…”

“…E. minus resprouts within weeks of a fire and recovers rapidly and can reach pre-fire levels within 2 years of burning and will continue to grow considerably for up to 17 years post fire (Srivastava et al 2013). The vegetation of Fraser Island is laterally zoned following the contours of successive parabolic dune systems that run parallel to the islands coastline (Donders et al 2006) older dunes generally lying to the west, overlaid partly by progressively younger dunes to the east (Lennon 2012;Moss et al 2016). Nutrient availability increases with the age of the sand and amount of detritus initially then declines due to leaching through a retrogressive successional process (Walker et al 1981; Longmore and Heijnis, 1999; Donders et al 2006).…”

“…Nutrient availability increases with the age of the sand and amount of detritus initially then declines due to leaching through a retrogressive successional process (Walker et al 1981; Longmore and Heijnis, 1999; Donders et al 2006). Zonation and succession of plant communities are dictated by salinity, water table, age and nutrient status of dune sands, exposure and frequency of fires, which creates an east to west sequence of vegetation (Lennon 2012;Moss et al 2016).

Changing Fire Regimes in Tropical and Subtropical Australia

The focus of the study is to investigate regional and local past, present and future changes in fire regimes of tropical and subtropical Queensland and shifts in vegetation composition and structure. Fire has been shown to be a significant driver of ecosystem evolution, composition and distribution through its impact on biota. Within Australia fire has long played a role in shaping the landscape, with increased fire frequency, associated with heightened aridity, over the last five million years promoting the expansion of fire adapted sclerophyll vegetation across the continent. Evidence of anthropogenic fires date back to approximately 50 ka (thousand years ago) with the advent of Aboriginal occupation and fire-stick practices, however with the arrival of Europeans there was a decline in fire frequencies, related to fire exclusion that observes an increase in fire intensity and severity.A review of the introduction of tropical African perennial grasses to improve grazing in tropical and semi-arid regions of northern Australia was also undertaken. This introduction has resulted in some exotic grass species such as Gamba grass (Andropogon gayanus), Mission grass (Cenchrus polystachios syn. Pennisetum polystachion) and Guinea grass (Megathyrsus maximus syn. Panicum maximum Jacq. var. trichoglume) becoming invasive pests. Invasion by these exotic grasses has serious implications for ecosystem function, altering fire regime dynamics through increasing the distribution and abundance of fine fuels. With increased fine fuels there is a serious danger that there will be an increase in fire frequency and intensity resulting in higher severity burns and higher vegetation mortality, with possible local species extinctions and habitat modification or change.Macro charcoal and pollen records were used from Fraser Island, subtropical eastern Australia to identify fire and vegetation histories, which show substantial temporal and spatial changes in past fire frequencies and vegetation composition for the last 24,000 years. Pollen records show pyrophobic rainforest taxa dominated and then declined while pyrogenic sclerophyll arboreal taxa increased correlating with an increase in fire frequencies, and a dryer climate. This was followed by a dramatic increase in Restionaceae values at the beginning of the Holocene (~10,000 years ago) that dropped off as a marked peak in mangroves, primarily the Rhizophoraceae and Melaleuca iii occurred, possibly linked with sea level rise approximately 6000 to 5000 years ago, which was also associated with lower fire frequencies. Restionaceae then recovered from around 2 ka to the European settlement period, when a dramatic change in fire frequency occurred linked to fire suppression and was followed by vegetation thickening (i.e. increase in arboreal taxa) in the mid to late 20 th century. Identifying past and present fire regimes and vegetation composition are important for fire modelling as this provides possible scenario based probabilities for changes in fire frequency and intensity....

Without management interventions, endemic wet‐sclerophyll forest is transitioning to rainforest in World Heritage listed K’gari (Fraser Island), Australia

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.
