Abstract. The Convention for Wetlands was signed in 1971 as part of a global measure to mitigate the loss and degradation of the world's wetlands. Signatory nations nominate wetlands as internationally important and commit to maintaining their 'ecological character'. In many cases the character that has been maintained was that occurring at the time of nomination with scant attention to the variability and change that occurs over longer periods. Palaeoclimate and palaeoecological research now reveals a diverse array of conditions in wetlands in the past and attests that any recently identified condition may be transient. The research further reveals the considerable magnitude and antiquity of the impact of people on wetlands. Hence the site description used by wetland managers would benefit from the provision of a longerterm perspective of change. The changing state of wetlands provides a dilemma for wetland managers. In response, a workshop on understanding change in wetlands was held in Queenscliff, Australia, in November 2013 to draw together perspectives of change from neo-and palaeoecological sources to enable the formulation of new pathways of assessment to better accommodate the dynamic nature of wetlands. A synthesis of the information provided at the workshop is provided in this paper.

“…The differences in burning trends may reflect the different settings of the core sites, with this studies site located on the edge of a lake and receiving direct input of large charcoal fragments but receiving less of the regional signal. In contrast, the core site discussed in Moss et al (2016) was situated in the centre of the lake, receiving a greater input from regional fires. Moss et al (2013) have discussed the importance of geographic setting for micro charcoal representation on North Stradbroke Island wetlands and a similar trend seems to be apparent for Fraser Island, which warrants further investigation.…”

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).…”

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....

Persistence of wetlands on North Stradbroke Island (south‐east Queensland, Australia) during the last glacial cycle: implications for Quaternary science and biogeography

Few Australian wetlands have persisted since the Last Glacial Maximum, with fewer still in existence through the entire last glacial cycle. The absence of wetlands, which itself indicates periods of moisture deficit, means there are few continuous climate and environmental change records covering this critical period. The lack of wetland persistence also raises the question of how plant and animal species that require permanent wetlands survived the last glacial cycle. Sixteen wetlands have been cored and dated on North Stradbroke Island (Minjerribah) – a large east Australian sand island – with basal dates reported from 10 sites for the first time. These wetlands range in age to over 200 000 years old, with six dating to the Last Glacial Maximum or earlier. There is no evidence of a stratigraphic discontinuity in the radiocarbon‐based age–depth profiles, suggesting continuous deposition of highly organic sediment through the period covered by these ages (c. 40 ka). The persistence of these wetlands suggests that for much of the last 40 000 years, and for perhaps much longer, the regional moisture balance has been positive. Over the last glacial cycle, persistently wet conditions may have provided a refuge from regional drying, and thus contributed to the high genetic diversity of rainforest plants in the region. Vegetation and climate records from these sites will allow hypothesis testing about the drivers of both local and regional climate variability. Copyright © 2017 John Wiley & Sons, Ltd.
