Assessment of Riparian Revegetation Trials on In-Channel Benches in the Hunter Valley of Southeast Australia

Large-scale river training works have been carried out in the Hunter valley since 1955 in response to flood-driven channel changes. Vegetation was planted on in-channel benches induced by river training works to consolidate the deposits and to increase channel boundary roughness. Exotic species of vegetation such as willows and poplars were previously used. In 1983, ten trial sites were planted with various species of native vegetation. Survival rates were evaluated in 1987 and 1997. The most successful species planted was Eucalyptus camaldulensis with an overall survival rate of 77 per cent in 1997. The Acacia species were found to be short-lived, exhibiting a significant decline in survival rates between 1987 and 1997. Survival rates for most species were higher on sand-bed than on gravel-bed sites. This difference may be attributed to better drainage on benches at the sand-bed sites. Investigations of flood disturbance showed that between 1983 and 1997 the sites were flooded between four and 13 times. The survival rates of Grevillea robusta and Eucalyptus melliodora trees were negatively correlated with the total number of recorded floods at each site. Poor natural regeneration of planted species is attributed to a combination of periodic flooding, intensive weed growth, low light intensities at ground level and grazing disturbance. These trials were not well designed for statistical analysis but provide valuable long-term information on the suitability of various species for planting in riparian rehabilitation programs. Such information is of relevance not only to river and catchment management authorities, but also to community groups.     

Is vitrification in charcoal a result of high temperature burning of wood?

The term ‘vitrified’ is used to describe the glassy appearance of some charcoals recovered in the archaeological record. It has been generally considered that this phenomenon is a result of wood being subjected to high temperatures similar to the role of temperature in the formation of glass and pottery. Charcoals displaying characteristics of vitrification from three distinct archaeological contexts were analysed using reflectance microscopy to determine their temperature of formation. Charcoal was also generated in laboratory charring experiments at temperatures of 900–1100 °C for durations of 1, 6, 12 and 24 h to determine if subjection to high temperature led to vitrification. None of the laboratory-produced charcoals displayed characteristics of vitrification. Mean random reflectance of the vitrified archaeological fragments indicated temperature of formation from 310 to 530 °C. A charring experiment was also conducted, at 500 °C for 6 h, using green wood with some bark attached, and added sugars, but no evidence of vitrification was seen. Therefore vitrified charcoals do not result from high temperature charring or primarily from the use of green wood.     

Public and private: national identities in a Scottish Borders community*

Abstract. This paper is an exploration of national identities among sports people in a community in the Scottish Borders. This group experiences a split in their identities. Publicly, they are ascribed an ambiguous national identity by the surrounding national communities. Privately, and among fellow community members, they unambiguously assert national identity. This paper examines the way this split is managed, arguing that the performance of public ambiguity is expected, but is supported by the private performance of nationality. National identity is analysed specifically as a performance, and sport is the context in which this performance takes place.     

Making hay while the sun shines? Socio-economic change,cereal production and climatic deterioration in Early Medieval Ireland

The Early Medieval period in Ireland (c. A.D. 400–1150) has been the subject of much archaeological and historical study. The recent application of various forms of archaeological sciences, as well as palaeoenvironmental studies, to the archaeological record have, however, added fresh impetus to this study area. It seems increasingly evident that significant changes to economy and society occurred during this period and were not recorded in detail in the contemporary documentary sources. This paper will attempt to outline those changes and to assess whether, or to what extent, they were influenced by climate change.     

The Ministry of Works and the Development of Souvenir Guides from 1955

The first formal guidebooks for historic sites placed in state guardianship in the United Kingdom appeared in 1917. There was an expansion of the series in the 1930s and 1950s. However, from the late 1950s the Ministry of Works, and later the Ministry of Public Buildings and Works, started to produce an additional series of illustrated souvenir guides. One distinct group covered Royal Palaces: the Tower of London, Hampton Court Palace, Queen Victoria’s residence of Osborne House on the Isle of Wight, and Holyroodhouse in Edinburgh. This was followed by guides for archaeological sites such as Stonehenge and Avebury, the Neolithic flint mines at Grime’s Graves, the Roman villa at Lullingstone, and Hadrian’s Wall. In 1961, a series of guides, with covers designed by Kyffin Williams, was produced for the English castles constructed in North Wales. These illustrated guides, some with colour, prepared the way for the fully designed guides now produced by English Heritage, Cadw, and Historic Environment Scotland.     

Prejudice: rethinking geographies of oppression

Despite equal opportunities legislation in many western societies, overt prejudice against minority groups is still evident. Yet, despite the persistence of equality issues, ‘prejudice’ is a term that is not widely employed in geography because of its association with a particular history of meaning within social psychology. In this paper I explore the concept of prejudice and its relationship to geographical research on discrimination and oppression. Then using original empirical research in three communities I examine how prejudice is justified and articulated by majority people. In doing so, I explore the complex intersectionalities of negative attitudes towards specific minority groups and the ways that specific mechanisms of sub-ordination can reinforce and support one another.     

Consuming campus: geographies of encounter at a British university

In this paper, we extend recent discussions on the geographies of encounter to examine how students and staff narrate their experiences of cross-cultural contact on a British university campus. In theory, the campus environment offers opportunities for more intense and prolonged forms of contact than the ephemeral micro-scale forms of interaction that have dominated much of the literature on encounters. In practice, however, our interviews suggest that many respondents tend to self-segregate, or in some instances are prevented from mixing with ‘others’ through institutional arrangements. As we also illustrate, the pressures posed by commercial forces on campus orientate certain students towards lifestyle choices and expectations which exclude others.
