‘On the move’? Maritime heritage and urban redevelopment in Melbourne

This paper explores issues surrounding the conservation and management of Polly Woodside, one of Victoria’s most significant maritime heritage objects. Sold to the National Trust of Australia (Victoria) for restoration in 1968, the ship has been berthed in the historic Duke’s Dock since 1978. Through various incarnations, the ship and associated museum have been a key feature of the Melbourne ‘riverscape’, and a major tourist attraction, ever since. The paper briefly explores the history of the Polly Woodside and museum, before focusing on the debates about the future use and location of the vessel brought about by the continuing redevelopment of Melbourne’s South Wharf from the mid-1990s until today. It examines how these contentious and often heated debates were shaped by different understandings of the ship's cultural significance, as well as ideas of community, ownership and sustainability, which have wider implications for the management of maritime cultural heritage within a context of urban redevelopment and place promotion.

World heritage: alternative futures

In 2009, the General Assembly of States Parties to the 1972 Convention for the Protection of the World Cultural and Natural Heritage (commonly known as the World Heritage Convention) established an open‐ended working group to debate, reflect on, and strategize for the future of the convention. Since that time, an array of scenarios for alternative directions has been discussed. At its fortieth anniversary celebration in Kyoto in 2012, the World Heritage Convention was referred to by many speakers as having reached a crossroads, a juncture at which a decisive path toward its future sustainability, credibility, and long‐term viability needs to be selected (Vujicic‐Lugassy 2013). Lengthy lists of challenges and gaps highlighted the shortcomings of the World Heritage Convention after four decades of implementation, and these now feature equally in contemporary discourses alongside those that refer to the convention’s enormous success and flagship status within UNESCO.While the World Heritage Convention’s popularity seems likely to increase, along with pressure for new World Heritage listings, the original intent of its authors – mutual support for conservation and international cooperation towards this end – seems to have shifted out of focus. In a time of growing utilization rather than implementation of the convention, its credibility is critically at stake.

The new heritage studies : origins and evolution, problems and prospects

Over the last three decades, community and professional views of what constitutes significant cultural heritage have broadened in many countries around the world. Heritage practice has moved from a narrowly technical or fabric focus to a values-based approach engaging all stakeholders, including indigenous communities. While much Western heritage knowledge and practice remains indispensable, gaps can be filled in by drawing on other knowledge areas and ethical considerations, including links between heritage practice and human rights. These new directions require new approaches in the preparation of practitioners as well as others engaged in heritage processes. In addition to education and training, a third concept – capacity-building – is overarching and potentially powerful in reaching new heritage actors. The aim of giving heritage a valued role in the life of the community, which applies at global, national, and local levels, represents the greatest challenge for educators, trainers, and capacity-builders in the contemporary world.

Crossing boundaries: exploring biocultural concepts and practices in the World Heritage system

This paper discusses current joint work by IUCN and ICOMOS to address issues that can arise when natural and cultural values and issues are considered separately within World Heritage processes. The Connecting Practice programme has conceptual and practical dimensions, and intersects with related work on rights-based approaches. Focusing on the importance of improving conservation outcomes, we propose a way forward situated in a 'middle ground' that links both theory and practice, and emphasises the critical importance of a joint approach - 'connecting' natural and cultural heritage practice. Some early findings of project field visits will be shared with the Scientific Symposium as a means of furthering the dialogue between practitioners.

When the virtual influences reality. The conservation project of the toledo gate in ciudad real (Spain)

The Toledo Gate of Ciudad Real, Spain, constructed between the late 13th and early 14th centuries, is the last remaining portion of a once complete medieval city wall. It represents the long history of the city and constitutes its main heritage symbol, dividing the historic city centre from the later 19th and 20th century expansions. In October 2012, the Town Hall and the Montemadrid Foundation started the conservation works to preserve this important monument. The preliminary phase of this project included an in-depth series of scientific studies which were carried out by a multidisciplinary team focusing on archival research, historic investigations, archaeological excavations as well as material composition analysis and main treatment application tests. As a result of these studies a series of virtual 3D models were created to inform, discuss and study the monument. A first digital model permitted visualization of the gate in the 19th century and how the main entrance to the city was integrated as a fundamental part of the city walls. This virtual reconstruction also became an important part of the campaign to raise awareness among the citizens towards a monument that had remained in the shadows for the last century, isolated in a roundabout after the systematic demolition of the city walls in the late 19th century. Over the last three years and as a result of these archaeological and historic investigations and subsequent virtual models, surprisingly new and interesting data were brought to light thus permitting the establishment and corroboration of a new and updated hypothesis of the Toledo Gate that goes beyond the previous ideas. As a result of these studies a new architectural typology with construction techniques of has been suggested. This paper describes how the results of this continuous and interdisciplinary documentation process have benefitted from a computer graphic reconstruction of the gate. It highlights how virtual reconstruction can be a powerful tool for conservation decision making and awareness raising. Furthermore, the interesting results of the final reconstruction hypothesis convinced the technical team responsible for the conservation to alter some aspects of the final project physical interventions in order to focus on some of the features and conclusions discovered through the virtual model study.

Evolution and significance of the regeneration reserve heritage landscape of Broken Hill: history, values and significance

In 1991, the National Trust of NSW classified the Regeneration Reserves surrounding the City of Broken Hill as an essential cultural heritage asset of the City of Broken Hill, and in 2015 the City of Broken Hill, including the reserves, were elevated to the National Heritage List under the Commonwealth's Environment Protection and Biodiversity Conservation Act 1999. This tract of land, and its proponents, Albert and Margaret Morris, are recognised as pioneers of arid zone revegetation science in Australia; a point noted in the National Heritage List citation. They created at Broken Hill a unique revegetation ‘greenbelt’ of national ecological, landscape architectural and town planning significance. The Morris’ led the advancement of arid zone botanical investigation and taxonomic inquiry, propagation innovation, and revegetation sciencein the 1920s-40s in Australia and applied this spatially. Their research and practical applications, in crafting the regeneration reserves around Broken Hill, demonstrated the need for landscape harmonisation to occur to reduce erosion and dust damage to human and mining activities alike. This pioneering research and practice informs and underpins much arid zone mine reclamation and revegetation work in Australia today. This paper reviews the historical evolution of this cultural landscape, its integral importance to the cultural heritage and mining history of the City of Broken Hill, and its inclusion as part of the Broken Hill National Heritage List citation.

Heritage diplomacy: entangled materialities of international relations

The paper explores the concept of heritage diplomacy in order to critically examine the links between conservation, cultural aid and hard power, and the dance between nationalism and internationalism. Three themes - venues, cooperation, and borders - orient the discussion, opening lines of enquiry previously ignored by scholars in a variety of fields concerning the entanglements between the past and the enterprise of preserving its material culture, and our unfolding histories of globalization and international affairs.

A first insight on the biodegradation of limestone - the case of the World Heritage Convent of Christ

The present study is a multidisciplinary approach applied to architectural stone materials of the Convent of Christ in Tomar (Portugal) in order to understand and mitigate the active decay processes. The structure and appearance of the stonework from the Convent of Christ are strongly affected by stains, biofilms and structural degradation. To investigate these phenomena, a multianalytical approach comprising X-ray microdiffraction, scanning electron microscopy, microRaman and microinfrared spectroscopy was applied to the examination of altered outdoor stone areas being detected calcium oxalates, carotenoids and microbial proliferation. The presence of these alteration products seems to be correlated with the microbial activity of bacteria, microalgae, cyanobacteria and filamentous fungi. This work showed that the application of complementary methodologies is an efficient strategy to characterise the stone decay, and constitute a starting point for successful conservation intervention plans that are urgent to ensure the preservation and safeguard of this emblematic monument.

Development and optimisation of protocols for surface cleaning of cultural heritage metals

The conservation and valorisation of cultural heritage is of fundamental importance for our society, since it is witness to the legacies of human societies. In the case of metallic artefacts, because corrosion is a never-ending problem, the correct strategies for their cleaning and preservation must be chosen. Thus, the aim of this project was the development of protocols for cleaning archaeological copper artefacts by laser and plasma cleaning, since they allow the treatment of artefacts in a controlled and selective manner. Additionally, electrochemical characterisation of the artificial patinas was performed in order to obtain information on the protective properties of the corrosion layers. Reference copper samples with different artificial corrosion layers were used to evaluate the tested parameters. Laser cleaning tests resulted in partial removal of the corrosion products, but the lasermaterial interactions resulted in melting of the desired corrosion layers. The main obstacle for this process is that the materials that must be preserved show lower ablation thresholds than the undesired layers, which makes the proper elimination of dangerous corrosion products very difficult without damaging the artefacts. Different protocols should be developed for different patinas, and real artefacts should be characterised previous to any treatment to determine the best course of action. Low pressure hydrogen plasma cleaning treatments were performed on two kinds of patinas. In both cases the corrosion layers were partially removed. The total removal of the undesired corrosion products can probably be achieved by increasing the treatment time or applied power, or increasing the hydrogen pressure. Since the process is non-invasive and does not modify the bulk material, modifying the cleaning parameters is easy. EIS measurements show that, for the artificial patinas, the impedance increases while the patina is growing on the surface and then drops, probably due to diffusion reactions and a slow dissolution of copper. It appears from these results that the dissolution of copper is heavily influenced by diffusion phenomena and the corrosion product film porosity. Both techniques show good results for cleaning, as long as the proper parameters are used. These depend on the nature of the artefact and the corrosion layers that are found on its surface.

Endangerment and Likeability of Wildlife Species: How Important are they for Payments Proposed for Conservation?

This paper examines empirically the relative influence of the degree of endangerment of wildlife species and their stated likeability on individuals' allocation of funds for their conservation. To do this, it utilises data obtained from the IUCN Red List, and likeability and fund allocation data obtained from two serial surveys of a sample of the Australian public who were requested to assess 24 Australian wildlife species from three animal classes: mammals, birds and reptiles. Between the first and second survey, respondents were provided with extra information about the focal species. This information resulted in the dominance of endangerment as the major influence on the allocation of funding of respondents for the conservation of the focal wildlife species. Our results throw doubts on the proposition in the literature that the likeability of species is the dominant influence on willingness to pay for conservation of wildlife species. Furthermore, because the public's allocation of fund for conserving wildlife species seems to be more sensitive to information about the conservation status of species than to factors influencing their likeability, greater attention to providing accurate information about the former than the latter seems justified.
