Determinants of native avian richness in suburban remnant vegetation : implications for conservation planning

While urban areas are increasingly recognized as having potential value for biodiversity conservation, the relationship between biodiversity and the structure and configuration of the urban landscape is poorly understood. In this study we surveyed birds in 39 remnant patches of native vegetation of various sizes (range 1–107 ha) embedded in the suburban matrix in Melbourne, Australia. The total richness of species within remnants was strongly associated with the size of remnants. Remnant-reliant species displayed a much stronger response to remnant area than matrix-tolerant species indicating the importance of large remnants in maintaining representative bird assemblages. Large remnants are important for other ecological groups of species including migratory species, ground foraging birds and canopy foraging birds. Other landscape (e.g. amount of riparian vegetation) and structural components (e.g. shrub cover) of remnants have a lesser role in determining the richness of individual remnants. This research provides conservation managers and planners with a hierarchical process to reserve design and management in order to conserve the highest richness of native species within urban areas. First of all, conservation efforts should preferentially focus on the retention of larger remnants of native vegetation. Second, where possible, riparian vegetation should be included within reserves or, where it is already present, should be carefully managed to ensure its integrity. Third, efforts should be focused at maintaining appropriate habitat and vegetation structure and complexity.

Impact of stresses imposed on macroinvertebrate communities in two suburban streams

The aim of the project was to determine factors which explain the distribution of macroinvertebrates in two Melbourne streams both drastically affected by urbanisation. A detailed description is given of Dandenong Creek, flowing through the south-eastern suburbs, and Darebin Creek, in the northern suburbs, emphasising stream features likely, or known, to influence the drift and benthic fauna. Faunal sampling was carried out in Dandenong Creek from June 1992 until July 1993, and in Darebin Creek from February 1995 until March 1998. Physicochemical parameters were also recorded. The collected data, together with previously existing data, were analysed using multivariate analyses: non-metric multi-dimensional scaling (NMDS); analysis of similarities (ANOSIM); matching biotic and abiotic variables using BIOENV, and principal component analysis (PCA). Various biotic and diversity indices were calculated in an attempt to identify the major factors responsible for the failure of the fauna to recover from previously more seriously degraded water quality. The contribution of drift to the colonisation potential in Dandenong Creek appeared to be impacted by retarding basins, underground barrel-draining and channelization. Results also indicated that increased conductivity adversely affected the fauna in the lower reaches of Dandenong Creek. It was concluded that in Darebin Creek, high nutrient levels, as well as other pollutants, had resulted in low macroinvertebrate diversity in both the drift and benthos. If, as this study suggests, faunal diversity is a valid measure of stream health, the following factors need to be addressed for catchment-wide, stream management: lack of riparian zone vegetation (increasing bank erosion and making the benthic habitat unstable, with greater temperature variability); control of stormwater runoff (flow variability, increased conductivity, nutrient levels, sediment loads, sewage effluent, industrial discharges and heavy metals), and to modify retarding basins to increase stream continuity.

Negotiating emotions, rethinking otherness in suburban Melbourne

I argue that research that tries to makes sense of emotion provides a better understanding of the politics and ethics of doing face-to-face research. Reflecting on in-depth interviews with people who live and/or work in Dandenong, an outer suburban area of Melbourne, I draw attention to the emotional dimensions of the research process. In particular I focus on moments when the exercise of white privilege made it difficult to negotiate emotions. These were moments when the intersection of my ethnicity with my position as a new settler in Dandenong made me feel excluded. The outcome was that I found it hard to value the voice of participants who were eager to help me with my research. A critical reflection of the emotions produced during such interpersonal encounters, however, has enabled me to rethink moments when the Self/Other binary unintentionally emerged. Critical self-reflexivity that is attentive to emotions gave me the opportunity to move closer to my goal of being an ethical researcher.

Interethnic understanding and belonging in suburban Melbourne

Modelling and mapping ethnicity is a methodological approach used to understand the changing socio-spatial structure of the city. Such an approach uses a range of indicators to identify ethnic groups, map them in urban space and explain the changing nature of ethnic concentrations. The unintended consequences, however, are the labelling, marginalisation and exclusion of ethnic minorities. Critical approaches, in contrast, focus on making visible the politics of representation that mark and stereotype ethnic minorities and ethnic concentrations. Within contemporary research on ethnicity such work has drawn attention to the exercise of power in the constitution of ethnic identities, the invisibility of whiteness and the inherent tensions that are likely to arise in negotiating ethnic cultural differences in local places. Although this article draws attention to such tensions in a particular place, Dandenong, it engages in this discussion to argue that the everyday negotiation of cultural difference also provides the potential to blur fixed ethnic boundaries and contribute to interethnic understanding and a sense of belonging. Drawing on in-depth interviews with people who live and/or work in Dandenong, suburban Melbourne, this article underlines that such positive insights from everyday multiculturalism have the potential to inform and broaden policy debates on diversity and social inclusion in the multicultural city.

Re-imaging citizenship in suburban Australia

Formal citizenship focuses on the provision of rights and responsibilities by the nation state. Such an understanding of democratic citizenship, however, is limited in providing social inclusion in everyday life, if cultural practices privilege whiteness. Although this paper draws attention to such practices that mark the ethnic Other, it also demonstrates the potential that exists to shift the boundaries of white privilege and negotiate dominant narratives of citizenship. Using a theoretical and methodological approach that focuses on poststructural and feminist ideas, I argue that the ways in which place is produced through reiterative everyday practices, makes place a site of transformative social change where white privilege can be questioned and difference welcomed. I draw on 54 indepth semi-structured interviews with people who live and/or work in the City of Greater Dandenong, suburban Melbourne, Australia to makes visible these everyday reiterative practices, and illustrate how they can be conceptualised as acts of responsibility, rather than just repetitive acts of hostility and suspicion. From my intersecting and shifting subject positions as a woman, a resident, ethnic, migrant, and Indian, the visibility of such practices makes it possible to re-imagine citizenship in the local neighbourhood, the city as well as the nation.

Home based business in suburban peripheral regions and government policy: a case study of Casey, Melbourne, Australia

Home based businesses (HBB) are increasingly becoming an alternative to salaried employment. This research explores the potential for HBB to contribute significantly to the economic development of peripheral metropolitan centres. Without economic development, these centres remain dormitory suburbs with unresolved associated social and ecological issues. By mapping the diversity and limitations of HBB in the City of Casey, an outer suburban peripheral area of Melbourne, Australia, this study aims to evaluate what exists and the response by governments at all levels to further business development. This study finds that the role of government is restricted to broad initial start-ups, with no programs or support for the type of innovative HBB that need to be husbanded and encouraged to grow outside of the narrow confines of their home base.

Darwin after dark: illuminating suburban atmospheres

In Australian cities, culturally diverse suburban landscapes are often sensed as discomforting sites of fear and anxiety, particularly after dark. Imagined risks of encounters with bodies of colour easily policed during the day when vision is clear, but who escape biopolitical regimes of securitisation and surveillance at night contribute to such atmospheric qualities of place. These affective atmospheres of fear and anxiety that haunt bodies and limit their ability to inhabit public space, however, can provide a sense of freedom for bodies who claim suburban spaces of darkness through tactile and sonic senses. This paper draws on the contemporary literature on affective atmospheres to show how racialised Indigenous and asylum seeker bodies become present in different ways in suburban places in Darwin after dark. The paper focuses on two events – spontaneous dancing to Indigenous music at Mindil beach market and a Vigil commemorating asylum seeker lives in a suburban courtyard. Drawing on ethnographic research I explore these affective intervention that illuminate dark suburban atmospheres in Darwin. Such interventions that draw attention to the attunement of bodies to difference unsettle biopolitical regimes that victimise and patronise visible non-white bodies and contribute to rethinking racism and darkness in suburban Darwin and the Top End.

A good place to raise a family? Comparing parents, service-providers', and media perspectives of the inner and outer suburban areas of Melbourne

In Australia, the suburbs have historically been the favoured place to raise children. However this is being challenged both by social change and government policy encouraging innerurban renewal. We examined how inner-urban areas compare with more traditional suburban locations as places to raise a family. Recognising that there are many influences on perceptions of place, we included the opinions of parents, service-providers and the media in the two locations.

Research focused on two municipalities in Melbourne, one located >25km and the other <10km from the CBD. Themes were obtained and compared from in-depth interviews with parents, serviceproviders and analysis of municipality-specific and state-wide newspaper articles.

Service provision was the only theme common at all levels of analysis. For all other themes, differences occurred between perspectives of service-providers, media and parents, as well as between the two residential locations. These in-depth snapshots on the challenges and rewards of raising children in different urban locations can help inform government in planning healthy neighbourhoods that better serve the needs of contemporary Australian families.
