Five types of spores of the endomycorrhizal fungus, Endogone, were abundant in the coastal sand dunes of New South Wales. Spores of Endogone have seldom been reported from marine dunes, and at least two of the spore types recovered from Australian dunes have not previously been reported from this continent. The density of spores in sand was greater in older, more stabilized dunes than in younger foredunes and mobile dunes.

Root samples of 41 sand-dune plant species in 28 families were collected from sites along the coast of New South Wales during spring 1987. Of the species, 36 had vesicular-arbuscular mycorrhizas, with vesicles and internal and external hyphae. Among these species there was great variation in the pro- portion of root length colonised by vesicular-arbuscular mycorrhizal fungi (from 1 to 96%); in 33 species over 10% of root length was infected. Of the vesicular-arbuscular mycorrhizal species, 21 showed arbuscules, and 16 had intracellular hyphal coils. In four plant species mycorrhizas were not found in the single samples examined; ericoid mycorrhizas were present in the remaining species, Leucopogon parviflorus, but its vesicular-arbuscular mycorrhizal status could not be assessed. The results, though preliminary, may reflect a high vesicular-arbuscular mycorrhizal status of vegetation of coastal sand-dunes of New South Wales. This would be likely to enhance plant nutrition and sandbinding, and to have implications for sand-dune management.

The Odonata and physicochemical properties of freshwater streams, lakes, ponds and bogs in the sand-dune systems of Fraser, Moreton and North Stradbroke Islands and Cooloola, Queensland: and Wooli, New South Wales, are described. The odonate faunas of these dune masses show some differences from those of nearby areas, and there are close associations between some species and particular types of dune fresh water. Although no physicochemical characteristics were identified that might limit these dune dragonflies to their specific habitats, the lake-dwellers in particular may be useful indicators of environmental change.

Tin City: Nomadic occupation, colonization and resistance in the sand dunes of Stockton Bight, Australia

European Colonization

This article explores nomadic site occupation as a form of planetary colonization involving both human and non-human agents. Conventional understandings of temporary occupation are often humancentric with little attention paid to the disruption of extant site ecologies and processes. The latter are particularly pressing concerns in nomadic settlements located in precarious landscapes. Taking the latter as its focus, this article engages the earth as an agent resisting its own colonization in the Australian-licensed squatter settlement known colloquially as Tin City. Located within the largest mobile sand dune structure in New South Wales, Tin City is an assemblage of several self-built fishing shacks accommodating a nomadic population. Its occupants engage in a daily battle against the shifting sands that threaten to subsume their temporary homes. Located in an area of significant indigenous heritage, the Tin City settlement has become a tourist attraction shrouded in local lore. Current discourses about it and its architectures generally focus on its unusual aesthetics, its contested sociopolitical histories and its ecology, with some discussion on the impacts of European colonization on the sand dune’s dynamic geomorphology. To concentrate on the latter, the article develops and deploys the posthumanist conceptualization of the earth posited by Iranian philosopher Reza Negarestani in his ficto-critical text Cyclonopedia: Complicity with Anonymous Materials. Negarestani ascribes the earth with sentient and agentic capacity, whilst the nomads who traverse its surfaces become the penultimate planetary colonizers. Tin City’s occupation thus becomes a story of colonization and resistance narrated by the earth itself, and a reminder that the production and consumption of architectural forms does not need to be confined to that which is conventionally human.

Mobile Dunes

<p>Coastal dunes are dynamic landforms whose morphology is governed primarily by climate and vegetation dynamics. Over the last 50 years, coastal sand dunes across the globe have dramatically ‘greened’ and wind speeds fallen (Pye et al., 2014; Delgado-Fernandez et al., 2019; Jackson et al., 2019), reducing aeolian transport of sediment and minimising dune reshaping by near-surface winds.  This rapid vegetation has also been attributed to a dramatic decline of several rare species of plants and invertebrates in several coastal dune systems (Howe et al., 2010; Pye et al., 2014). In an effort to increase habitat diversity, large-scale vegetation removal and dune re-profiling are becoming increasingly common interventions. However sustained aeolian activity following intervention appears to be rare (Arens et al., 2013).</p><p>In order to better understand the environmental drivers of long-term dune mobility, this work explores the landscape scale physical factors related to self-sustaining ‘natural’ mobile dunes across the United Kingdom. The analysis presented includes the use of geographically weighted regression, a spatial analysis technique that models the local relationships between predictors (e.g. wind speed, slope, elevation, aspect, surface roughness) and an outcome of interest (mobile dunes). It is hoped that the results of this work will help guide decision-making with regards the location, scale and morphology of future interventions in order to maximise their sustainability, minimising the need for maintenance and further intervention.</p><p>References</p><p>Arens, S.M., Slings, Q.L., Geelen, L.H. and Van der Hagen, H.G., 2013.

The dusky hopping mouse, Notomys fuscus, is a desert rodent that occurs in the Simpson Strzelecki Dunefield Bioregion in Queensland, South Australia and New South Wales, where stabilised sand dunes are its preferred habitat. A recent capture from the Broken Hill Complex Bioregion in an atypical habitat (bluebush shrubland) and new locality ~170 km south of the nearest New South Wales record may indicate a significant population eruption and subsequent migration into new areas following the widespread ephemeral and perennial plant production pulse that occurred in 2010.
