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.

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.

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.

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.

Dry Soil

Spores of vesicular arbuscular (VA) mycorrhizal fungi were found in all 73 soil samples collected from different parts of New South Wales. Their numbers ranged widely from site to site (from 2 to 1952 spores per 100 g dry soil) and varied considerably for the same crop at different sites (e.g. from 47 to 464 spores per 100 g dry soil for wheat). In general there were more spores in agricultural than in native grassland-bush soils. Of the eight species found, Acaulospora laevis and Glomus mosseae were the commonest. Small spores of the Glomus fasciculatus and G. microcarpus groups were also frequent but Gigaspora spp. were fairly rare. Usually more than two VA species occurred at each site. The infectivity of the VA population in soil, assayed by measuring the rate of mycorrhizal develop- ment in clover seedlings, did not correlate with spore numbers.

Colonisation of wheat crops by vesicular-arbuscular mycorrhizal (VAM) fungi was examined on a pair of adjacent organic and conventionally managed farms in southern New South Wales during 1993-94. Although intended to be part of a larger study on the roles of VAM fungi in organic and conventional farming systems, the severe drought of 1994 allowed an examination of the effects of drought on VAM fungi. In 1993, rainfall was above average, crop growth was good and VAM fungi colonised between 40 and 70% of crop root length. In 1994, low rainfall resulted in poor crop growth, and colonisation by VAM fungi was significantly lower than in 1993, ranging between 5 and 16% in the crops most affected by the drought. Wheat plants adjacent to tree lines exhibited particularly poor growth and low VAM colonisation, presumably due to the trees competing with the crop for water. The lower colonisation of crops by VAM fungi in 1994 resulted in reduced inoculum levels in the soil which could affect growth of a subsequent VAM-dependent crop. In contrast to the results of research carried out under conditions of milder drought stress, the low level of VAM colonisation found in this study suggests that the VAM fungi had no significant role in alleviating the drought stress experienced by the crop.
