Lawns have evolved from medieval European grasslands into globally accepted urban green surfaces, serving recreational, aesthetic and cultural purposes. Today lawn surfaces are essential components of public urban green space (PUGS), fulfilling ecosystem services such as urban heat mitigation, carbon sequestration and social well-being. However, their ecological and resource-intensive disservices, particularly in dry climates, have prompted growing concerns among environmental scientists, urban planners and landscape designers. In water-scarce regions like Perth, Western Australia, traditional lawns face increasing scrutiny due to their high irrigation demands and limited ecological diversity. This study contributed to the transdisciplinary LAWN as Cultural and Ecological Phenomenon project, focusing on the perspectives of professionals, landscape architects, park managers, turf producers and researchers responsible for the planning, design and management of urban lawn in PUGS. Using qualitative methods (semi-structured in-depth interviews), the research explores expert insights on the values, challenges and future trajectories of lawn use in a warming, drying climate. The interviews included 21 participants. Findings indicate that while professionals acknowledge lawns’ continued relevance for sports and active recreation, water scarcity is a major concern influencing design and species selection. Alternatives such as drought-tolerant plants, hard landscaping and multifunctional green spaces are increasingly considered for non-sporting areas. Despite growing concerns, the ideal lawn is still envisioned as an expansive, green, soft surface, mirroring entrenched public preferences. This study underscores the need to balance environmental sustainability with public preference and cultural expectations of green lawns. Balancing expert insights with public attitudes is vital for developing adaptive, water-conscious landscape design strategies suited to future urban planning and environmental conditions in Mediterranean climates.

This study focused on visitors undertaking recreational activities at two important wetland conservation reserves with two main aims: to understand if visitors recognize the significant role of wetlands as vital bird habitat, and to understand the importance of birds as part of the visitor experience. We surveyed 511 visitors at two internationally significant urban wetlands in Perth, Western Australia. Results indicated that respondents valued wetland areas for exercising, aesthetic values, utility of infrastructure and general amenity, as well as the presence of birds. Some respondents perceived that the wetlands were important for birds and the presence of birds was generally rated highly. Results further indicated that while birds were generally not the focus of visitor experience, birds were an important component of that experience. We conclude that most visitors will generally support management actions aimed at conserving the wetlands and birdlife, and management actions do not need to consider a range of differing views across different recreational activities. Thus, understanding the extent that different recreational users of urban wetlands value birds and bird habitat provides vital insights into management approaches for conservation.

Communication is a strategic management lever for promoting user knowledge, understanding, acceptance, support, and conservation-related pro-environmental behavior within Coastal and Marine Protected Areas (CMPAs). But while user segmentation is considered a traditional operational tool for targeting user audiences effectively within terrestrial protected areas, research also highlights a low level of concrete application to CMPAs. Based on Public Perceptions Research literature, this study explores a panel of eight theoretical variables that reflect the multidimensional character of recreationists’ perceptions of CMPAs and how the related results could inform appropriate CMPA communication strategies. Onsite face-to-face interviews with 1,000 users were conducted for seven recreational activities (hiking, surfing, scuba-diving, boating, sailing, kite-surfing, kayaking) across a total of ten local sites. Results revealed that despite sharing a common motivation for being in contact with nature, recreationists expressed diverse perceptions and attitudes toward CMPAs and management, which can be divided into five segments: “CMPA-Not-convinced” (31.3% of all recreationists), “CMPA-Local Conservator” (11.5%), “CMPA-Not-Responsible” (12.7%), “CMPA-Passers-by” (20.1%) and “CMPA-Convinced” (24.4%). Findings show the value of visitor segmentation as an operational tool to inform CMPA management and communication strategies in a context of low knowledge about visitor audiences.

Lawns, introduced in Australia through English colonial heritage, dominate public spaces in cities, serving various ecosystem functions. Australian lawns consist of non-native grasses that differ from native original vegetation and require intensive management and maintenance. This study explores public perspectives on urban lawns in Perth, Western Australia, an area largely overlooked in ecological and social research in the context of Australia compared to Europe and North America. This paper presents empirical research on public perceptions of urban lawns and alternatives in Perth, Western Australia. The study explores social values and preferences regarding traditional lawns and new options, considering visual appearance, uses, and maintenance. Findings from an online questionnaire, involving 171 respondents, identified seven categories based on a content analysis of lawn definitions: flat area; ground covered by grass; maintained; non-native vegetation; open space; recreational space; and turf grass. The results revealed that respondents most value lawns for aesthetics, cooling and recreation (exercises, walking pets, as a transit area, passive recreation, and social gatherings). At the same time, participants demonstrated an environmental awareness of lawns and the necessity of revisiting the existing planning and maintenance routine based on irrigation and intensive mowing by considering several alternative solutions. While valuing new solutions such as Scaevola patches in dedicated areas and “weedy lawns”, participants still preferred alternatives closest in appearance to a conventional lawn (e.g., lawn grass with Dichondra and lawn grass with clover). The study emphasizes the need for a ‘blended model’ of urban lawns, combining durability with heat-resistant, biodiverse vegetation to address social values and environmental concerns.

Urban nature and ways of protecting, designing and even mimicking natural processes are some of the most popular themes inspiring humanities and natural science studies in different disciplines around the globe. Urban nature, green infrastructure and nature-based solutions are three intertwined concepts. This paper will highlight some of the many visions for urban nature (e.g., four urban natures: native, cultivated, designed/horticultural and spontaneous natures) and interpretations of nature-based solutions. While there are some similarities in the interpretation of urban natures by different disciplines, some significant differences exist. This paper analyses and synthesises knowledge from divergent theoretical concepts of urban natures in Europe and Australia, and the associated ecological concepts of novel and designed ecosystems. The complexity of urban natures and native landscapes has fostered the development of several typologies that often lead to misunderstanding between discipline areas and difficulties with practical implementation, such as in urban planning or landscape design. We argue that differences in interpreting the scope of urban nature are often underlined by the specific socio-political, historical, cultural and ecological contexts of a country or region (e.g., Australia and Europe). By applying an interdisciplinary approach, we explore the concept of urban natures by analysing and synthesising links between different disciplines. A transdisciplinary perspective is an important premise for collaboration between ecological sciences and landscape architecture in many restoration projects, or when social and ecological sciences jointly address societal challenges with the help of nature-based solutions co-created using participatory approaches. The latter highlights the role of transdisciplinary research to link practitioners, policymakers and scientists, helping to engage with citizens and inform design. The analysis of several examples from Europe and Australia allowed us to depict different approaches to existing urban natures and methods of their design, enhancement and conservation. These examples highlight that different urban natures are sources of inspiration for nature-based solutions that can be successfully implemented in contemporary landscape and planning practice.

Urban vegetation provides many social and environmental benefits, yet integrating diverse vegetation into urban areas can be difficult due to spatial and financial constraints. Naturalistic streetscape plantings have gained popularity as a method to improve vegetation diversity without requiring additional land or maintenance costs. In temperate climates, these plantings are typically meadow-style and informed by research on people’s preferences. Yet in mediterranean-type climates, naturalistic plantings reflect shrub-dominated native vegetation, for which public aesthetic preferences are largely unknown. To address this gap we conducted an online survey in Perth, Australia where respondents (n = 985) rated their preferences for 32 computer-generated images of public streetscape, naturalistic, woody plantings that differed in structure (low (<1 m), mid, and upper (>2 m)), flower presence, foliage colour, and visual symmetry. These were compared to an image of low-input lawn, representing a typical local government-maintained streetscape. We also assessed how environmental worldviews, plant knowledge, demographics, and suburb scale tree cover influenced preferences. Naturalistic woody plantings were liked by 88%, and lawn disliked by 87% of respondents. The most preferred aspects of naturalistic plantings were multiple structural layers, flowers, and both green and grey foliage. Positive preferences for naturalistic plantings and dislike of lawn were stronger from respondents with pro-environmental worldviews, greater plant knowledge, and who resided in suburbs with higher tree cover. Therefore, we recommend naturalistic woody plantings as a publicly acceptable method to improve streetscape quality. Overall, this research provides insights into the nexus between social and ecological values of streetscape plantings for the planning and design of sustainable urban greening in a warming, drying mediterranean-type climate.

As recreational fishers act relatively autonomously, management relies heavily on voluntary compliance. Therefore, understanding fishers’ views on management options can be beneficial. This study used a two-phase approach of face-to-face interviews and subsequent online questionnaires to evaluate recreational fishers’ salient views on issues affecting the Blue Swimmer Crab (Portunus armatus) and Black Bream (Acanthopagrus butcheri) fisheries in Western Australia as well as current and potential management arrangements, including stock enhancement. The strength and heterogeneity of views were also determined. Minimum size limits were mainly considered acceptable or very acceptable, with restricting recreational fishing and spatial closures the least supported management options for both species, in addition to maximum size limits for crabs. These views were not always consistent across fishing locations for each species and among types of crab fishers, indicating heterogeneity in views. Stocking was the most acceptable of the management measures not already utilised for crabs and among the most popular for bream fisheries. Recreational fishers of both species believed stock enhancement could have strong positive outcomes for the abundance of their target species and increase their subsequent catches. They also recognized that some negative outcomes, e.g., increased fishing pressure and environmental issues, might occur but considered them unlikely.

City road verges often represent existing green space and provide opportunities for ecological enhancement. Urban greenspace improvement initiatives at the residential verge scale require genuine community support and engagement for success. We examined a community-based voluntary assisted verge greening program designed to enhance greenspace connectivity using native plants in a local municipality in Perth, Western Australia. A social survey of verge-greening program participants and non-participants was conducted to understand factors associated with community involvement. Results indicated general resident support for the program, where both groups viewed the program objectives positively. However, non-participants were less convinced, than participants, of the likelihood that the verge greening program would achieve its aims and the merits of some aims. This paper provides insight into a voluntary community engagement tool for developing urban green space connectivity and enhancing natural values at the residential roadside verge level.

Effective fisheries management requires an understanding of human dimensions. This study elicited the salient motivations for recreational blue swimmer crab and black bream fishing in Western Australia and whether these views differed depending on the fishing location and/or the characteristics of the fisher. Crab fishers were strongly consumption-orientated and aimed to “catch big crabs” and “catch enough crabs to eat”. Furthermore, 91% consumed their catch, with only 2% practicing catch-and-release fishing. In contrast, 81% of black bream fishers did so for the sport/challenge, with the strongest motivation being to catch a bream considerably above legal size and with food only selected by 15% of respondents; most fishers released caught fish. The marked differences between the fisheries for the two species, which co-occur in the same estuaries, are likely driven by the accessible nature of the crab fishery, ease of catching crabs, the low cost of fishing equipment, and their taste. Fishing for black bream, however, requires more expensive equipment, patience, and a greater skill level. Fishers considered crabbing to be as important as other fishing and outdoor activities, whereas bream fishers considered bream fishing considerably more important, reflecting the trophy nature of this fishery.

Invasive plant species (IPS) management in national parks is a complex problem often characterised by the involvement of various organisations with different responsibilities, legal mandates, and jurisdictions. These institutional arrangements shape the structure, function, and decision-making behaviours of organisations and influence management effectiveness. Drawing on institutional theory, this study analysed institutional arrangements and how these influenced IPS management in national parks of Vietnam. Data were collected between May and July 2017 using in-depth interviews with 39 key informants with responsibilities for IPS management at different institutional levels (national, provincial, local national parks). Results demonstrated that IPS management in Vietnam’s national parks was characterised by centralised management with overlaps and gaps in vertical institutional relationships that limited the effectiveness of horizontal relationships. These characteristics resulted in a lack of clear guiding regulations and limited resources that restricted decision making and hindered implementation at the local national park level. The study highlights the need for a common set of principles across agencies, governed by an overarching body to promote constructive relationships across the vertical and horizontal institutional dimensions of IPS management.
