Urban brownfields are found in all parts of the world. They suffer from a negative image, generally being viewed as problem areas. However, urban brownfields also offer potentials for new uses as well as for the ecological regeneration of cities. Especially urban brownfields with spontaneous vegetation can contribute to biodiversity and ecosystem services in dense urban environments. Whether and how this potential is exploited depends on the perception and preferred uses of brownfields by local residents.Through surveys undertaken in Dresden and Leipzig, this paper examines the perception and use of brownfields and their spontaneous vegetation by the urban population. Results show a range of views on brownfields with spontaneous vegetation from negative to positive evaluations. Many residents make use of brownfields, have concrete ideas about how such areas should be utilized or designed and are even prepared to take part in the transformation. The paper suggests that the use and design of green space should be rethought in unconventional ways, and discusses how the ecological and social potential of brownfields with spontaneous vegetation can be best exploited for urban residents. 相似文献

Urban plant diversity influences the social functioning and well-being of urban dwellers. However, the patterns and drivers of plant diversity in tropical urban areas are still not entirely understood. In response to the knowledge deficiencies in this area, we investigated spontaneous and cultivated plant richness and their phylogenetic diversity and relatedness in 260 Urban Functional Units (UFUs), which represented nine different land use types according to anthropogenic function, in the tropical coastal city of Zhanjiang, China. Plant diversity was modelled as a function of UFU characteristics and human maintenance practices. Spontaneous species richness was highest in urban villages and vacant lands and lowest in transportation areas, while phylogenetic diversity was highest in utilities and lowest in parks. In comparison, cultivated species richness was highest in multi-family residential areas and lowest in vacant lands, while phylogenetic diversity of cultivated species was highest in commercial/industry areas and lowest in agriculture areas. The number of cultivated species and the degree of phylogenetic relatedness of spontaneous species were positively correlated with the human population density. The phylogenetic diversity of cultivated species within UFUs was generally higher than that of spontaneous species. Human maintenance of landscapes acted as an environmental filter for spontaneous species, but also promoted the number of cultivated plants. We conclude that appropriate investment in urban green areas may improve both plant species richness and phylogenetic diversity in urban environments. 相似文献

Cities in China support higher human population densities compared to those in western countries; consequently, the high pressure placed on cultural ecosystem services (CES) provision of residential green spaces might hinder overall human wellbeing and the maintenance of avian diversity. Thus, this study aimed to identify how to meet the main preferences of citizens for residential green spaces while simultaneously enhancing bird diversity in city neighborhoods, generating a win-win scenario for human needs and biodiversity. This study was implemented using 568 questionnaires for residents and GLMM for bird-environment statistical analyses. Residents in Beijing preferred higher levels of bird species richness than individual abundance in neighborhoods. Residential green space appeared to serve as the movement corridor for some rare species, indicating the importance of promoting the presence of migrant bird guilds, which is currently incidental. The cultivation of fruit-bearing shrubby plants was supported by most city residents, and would also promote the presence of migratory birds in green spaces. In contrast, while increasing the width of residential green spaces would benefit migratory birds, it had less public support. This multi-disciplinary study clearly demonstrated that both the quality of life of humans in cities and biodiversity conservation could be efficiently incorporated in green space plans, even under highly urbanized circumstances. 相似文献

There is a growing body of literature examining the multifaceted benefits of community gardens for environmental and social wellbeing. While there are studies examining the increase of grassroots urban gardening initiatives in low income and vulnerable communities, there remains a need for research that explores the lived experiences of individuals in social housing communities with urban nature and community gardens. Individuals living in urban social housing may experience inequalities in access to green infrastructure both within their housing estates as well as the surrounding community. For the past two decades, the Community Greening program at the Royal Botanic Garden Sydney, Australia, has implemented outreach initiatives to support the development and maintenance of community gardens in social housing communities in New South Wales. This article presents the findings from a study conducted with participants at six new community gardens built in social housing communities, focusing specifically on focus group interviews with residents and staff questionnaires to examine the perceived impact of the Community Greening program. The participants’ narratives highlight program outcomes across the key themes of community gardens as sites for knowledge generation and connection to nature, sense of community, and improving residents' sense of pride and public perceptions of public housing. The findings suggest that community gardens enhance green infrastructure in social housing estates and their broader urban locales by improving access to green space and promoting place-making in social housing contexts. We conclude with a discussion of the recommendations and lessons learned that may help to inform future policies and practices when setting priorities that promote social and environmental sustainability in social housing. 相似文献

Activities in natural environments greatly enhance human well-being and can support the integration of foreigners into a new country. This article explores how residents from different ethnic backgrounds in Turku, Finland appreciated and engaged with urban natural environments and how this engagement benefitted their well-being and, ultimately, their integration. Individuals enjoy activities in nature in particular ways, which may vary according to a person’s physical, social, and psychological characteristics. This is especially true for immigrants who apply traditions from their home countries to the ways in which they interact with their new environment and enjoy activities in nature. Three dimensions of nature experience—social, emotional, and normative—emerged from the research, which, in turn, supported well-being and different types of integration: interactive, identificational, and cognitive. We argue that because these dimensions are an integral part of a person’s identity and cultural background, familiarity with them may prove pivotal to constructing more welcoming and intercultural urban natural environments. Different approaches to engaging with nature should be considered in the design of urban environments and urban nature, as well as in integration programmes, to enhance the well-being and integration of foreign-background populations. 相似文献

The idea that landscape has been created by human activities on a biophysical basis allows for clear cause–effect reasoning.
However, landscape planning and management practice learns that it is impossible to neglect the social perception of landscape,
i.e. the ways people think about nature and landscape. It is the result of social research and human sciences of the last
decade that a differentiation in views of nature and landscape can be identified in the different groups of social actors
in the landscape. Case studies from France and the Netherlands show a marked change in values attributed to nature and landscape
in the end of the last century. Social demand for landscape is growing and a shift from a functional image of nature and landscape
to a more hedonistic image like the Arcadian and wilderness images has taken place. Comparing the Netherlands with France
and rural with urban inhabitants, the influence of urbanisation is evident in this process. It is further shown that images
of nature vary considerably between for example farmers, urban residents, hunters and conservationists. The way people perceive
landscape seems determined by their functional ties with the landscape and the social praxis in which they encounter the landscape.
It is concluded that the concept of landscape is nearer to the lifeworld of people than the abstract notions of nature and
biodiversity. This implies a big challenge both for national and international landscape policies and for local landscape
management initiatives to be developed, taking into due consideration both the material and immaterial nature of landscape. 相似文献

As urban green spaces are important for residential satisfaction, human preferences are a key criterion in their design. However, preferences may vary between landscape planners and residents, which may result in differences between residents’ demands and the actual design. With urban derelict land becoming an important part of the urban green infrastructure, information about the perception and acceptance by residents compared to formal urban parks is important for their planning and design. It was thus examined how different types of urban green spaces are perceived by landscape planners and residents. Criteria for the classification of green spaces used by both participant groups were compared, as were the criteria that influenced preference.Participants sorted and rated photographs of parks and urban derelict land in two different tasks. Hierarchical cluster analyses and multidimensional scaling analyses were used to characterize the participants’ perceptual space. By conducting multiple regression analyses the resulting perceptual dimensions were related to preference.The identified perceptual criteria used to distinguish green spaces were degree of canopy closure, artificiality vs. naturalness, prospect, physical accessibility, and beauty. For residents, the degree of canopy closure was the most important criterion for classification; for landscape planners, it was artificiality. Preferences varied between groups: whereas landscape planners preferred rather natural areas with low accessibility and high species richness, the residents showed a greater preference for formal parks.As a practical implication, the study suggests that residents generally accept urban derelict land as recreational areas if a minimum of maintenance and accessibility is provided. When designing green spaces, landscape planners may consider these differences in their preferences compared to residents. 相似文献

Understanding the determinants of hedgerow plant diversity in agricultural landscapes remains a difficult task, because the
potential drivers affect the complete range of biodiversity components (alpha to gamma diversity). We surveyed herbaceous
plant communities (of a height <1.5 m) in 84 hedgerows in the Seine river floodplain of France. Two types of potential drivers
for species richness, accounting for landscape mosaic and hedgerow network, were recorded at both hedgerow and site scale.
The distribution of species richness through the components of alpha hedgerow diversity (i.e. the average diversity within
a habitat) and gamma hedgerow diversity (i.e. the total diversity across habitats) were assessed using additive partitioning
methods, while the relationship between species diversity and its potential landscape drivers at both scales was modeled using
Generalized Additive Models. Our results indicated that gamma hedgerow diversity is explained by the heterogeneity of the
landscape structure, which is correlated with the mosaic of agricultural land use. At this scale, intrinsic properties of
the configuration of the hedgerow networks have a weak influence on species richness. Alpha hedgerow diversity is also explained
by landscape variables, accounting for both the configuration of agricultural mosaics and hedgerow networks, but to a lesser
extent. Time lags for species responses are shown at both scales, and for the two types of drivers. Extinction or colonization
debt may be indicated at both scales, while the remnant effects of former practices may also be responsible for such patterns
at a local scale. We suggest that hedgerow management should take the specific parameters of both scales into account. At
a local scale, management actions should aim to decrease the influence of adjacent land use when the impact is negative, through
the implementation of extended buffer zones, while at the landscape and farm scales, agri-environmental schemes should be
dedicated to the conservation of specific agricultural land uses. 相似文献

A person’s health and wellbeing are contingent on the amount of social support that they receive. Similarly, experiencing nature has been shown to improve people’s health and wellbeing. However, we do not know how relationships between social cohesion, nature experiences and nature connection could interrelate and vary across different types of urban green spaces, and in non-Westernised cultures. We conducted a study on 1249 residents in Singapore, a tropical city-state, and measured three dimensions of social cohesion (i.e. general social cohesion; trust and sense of community; and social interactions), various types of nature experiences (i.e. amount of green space around one’s residence; frequency and duration of urban green space visits; frequency and duration of visits to gardens), and three dimensions of one’s connection to nature: self-identity with nature, desire to experience nature, and environmental concern (using the nature relatedness scale). We found that people who strongly identify with nature, who enjoy being in nature, and who had more frequent gardens visits were more likely to have a stronger sense of social cohesion across two dimensions. However, those with stronger environmental concern reported an overall weaker sense of social cohesion, possibly due to the perception that society’s contributions to conserve environmental problems was insufficient. Further, people who gardened more frequently were also more likely to visit green spaces, self-identify with nature and exhibit a stronger desire to experience nature. We propose that strategies targeted at encouraging people to engage in nature-related, collaborative activities at the local community level, such as spending time in local gardens, will increase urban residents’ daily nature experiences and its associated benefits such as improving social cohesion. 相似文献

The woody plant communities found on residential properties constitute an integral component of cities’ green infrastructure and serve as a nexus between urban residents and the natural world. Despite this importance, residential landscapes are infrequently designed with principles of sustainability in mind, resulting in the extensive use of pesticides to suppress a diverse array of plant pests. In this study, we ask whether ecological theory can inform the sustainable design and management of woody plant communities on urban residential properties. The associational resistance and dilution effect hypotheses are analogous hypotheses, which posit that increasing biodiversity can inhibit the abundance of herbivores and pathogens, respectively. Importantly, theory suggests that it might not just be diversity that matters, but the right kind of diversity (i.e., community composition). Previous studies have demonstrated that herbivore abundance can be greater on native plants compared to exotic plants in residential landscapes. However, little is known regarding whether this translates into greater numbers of interventions to reduce damage associated with plant pests on native plants. To test these hypotheses, we utilized a multi-year, commercial plant health care program dataset. We examined, at the residential property scale, the relationships between woody plant diversity, the percentage of plants that were native, and pest management interventions. We found that the number of pest management interventions targeting phytophagous arthropods, but not plant pathogens, was negatively related to woody plant biodiversity. The percentage of native plants on a property had no relationship with the number of pest management interventions that occurred. Consequently, efforts to increase woody plant biodiversity in residential landscapes could result in increased phytophagous arthropod pest suppression, thereby reducing the need for pesticide applications and their associated adverse effects. 相似文献

The spatial distribution of non-native, invasive plants on the landscape is strongly influenced by human action. People introduce non-native species to new landscapes and regions (propagule pressure) as well as increase ecosystem invasibility through disturbance of native ecosystems. However, the relative importance of different landscape drivers of invasion may vary with landscape context (i.e., the types and amounts of surrounding land cover and land use). If so, data collected in one context may not be appropriate for predicting invasion risk across a broader landscape. To test whether independent occurrence datasets suggest similar landscape drivers of invasion, we compared landscape models based on data compiled by the Invasive Plant Atlas of New England (IPANE), which are contributed opportunistically by trained citizen scientists, to models based on Forest Stewardship plans (FSPs), which are located in privately owned and relatively undisturbed forests. We evaluated 16 landscape variables related to propagule pressure and/or disturbance for significant predictors of invasive plant presence based on presence/absence and count regression models. Presence and richness of invasive plants within FSPs was most influenced by proportion of open land and proximity to residential areas, which are both sources of propagules in forest interiors. In contrast, IPANE invasive plant presence and richness for the same area was influenced by distance to roads and streams. These results suggest that landscape drivers of invasion vary considerably depending on landscape context, and the choice of occurrence dataset will strongly influence model results. 相似文献

Understanding which environmental conditions are critical for species survival is a critical, ongoing question in ecology. These conditions can range from climate, at the broadest scale, through to elevation and other local landscape conditions, to fine scale landscape patterns of land cover and use. Remote sensing is an ideal technology to monitor and assess changes in these environmental conditions at a variety of spatial and temporal scales, with many studies focusing on the physiological state of vegetation derived from time series of satellite measurements. As vegetation occurs within specific climatic zones, over certain soil, terrain, and land cover types, it can be difficult to decipher the influence of the underlying role of climate, topography, soil, and land cover on the observed vegetation signal. In this article, we specifically addressed this problem by asking the question: what is the relative impact and importance of these different scales of environmental drivers on the temporal and spatial patterns observed on a habitat index derived from remotely sensed data? To find the solution, we utilized a SPOT VEGETATION-normalized difference vegetation index time series of Europe to create a remote-sensing-derived habitat index, which incorporates aspects of productivity, seasonality, and cover. We then compared the observed temporal and spatial variations in the index to a pan-Europe terrestrial classification system, which explicitly incorporates variations in climate, terrain, soil parent material, land cover, and use. Results indicated that the most accurate level of discrimination from the habitat index was at the broadest level of the hierarchy, climate, while the poorest degree of discrimination was associated with elevation. In terms of similarity on the index across time and space, we found that arable and forest cover classes were more similar across elevation and parent materials than across other land cover types within them. Analyzing the remote-sensing index, at multiple scales, provides significant insights into the drivers of satellite-derived greenness indices, as well as highlights the benefit and cautions associated with linking satellite-derived indirect indicators to species distribution modeling and biodiversity. 相似文献

In a world of increasing urban areas and their subsequent negative effect on biodiversity, university campuses arise as environmentally friendly designs that can help enhancing biodiversity. However, current information on the topic is mainly based on single-campus studies, taxonomic diversity variables (e.g., species richness), and specific geographic regions like Asia or North America. Multi-campus comparisons, studies on other components of biodiversity (e.g., functional or phylogenetic diversity) and biodiversity information from other regions of the world are needed to generalize the previous findings. In this study, we try to fill in these gaps by simultaneously investigating taxonomic, functional, and phylogenetic diversity of bird communities on 15 university campuses of Spain, which is located within the Mediterranean hotspot of biodiversity where no previous study on this topic have been conducted. We compared campus areas with other randomly selected urban areas to test whether university campuses hold higher levels of bird diversity than non-campus areas. We also analyzed other environmental variables (e.g., green and building cover in and around campuses) to identify whether their influence in university campuses varies from other urban areas. Our results show that taxonomic diversity was higher within university campuses compared to other areas, but this pattern was not confirmed for functional and phylogenetic diversity. We found that grass cover, buildings, and the green area around the study areas have different associations with taxonomic, functional, or phylogenetic diversity respectively in campuses or non-campus areas. Our findings highlight the importance of university campuses for the conservation of Mediterranean urban biodiversity and support their use as relevant resources for promoting nature conservation among citizens. 相似文献

Context
Understanding the factors contributing to maintaining biodiversity is crucial to mitigate the impact of anthropogenic disturbances. Representing large proportions of green area in highly modified landscapes, residential gardens are often seen as local habitats that can contribute to larger networks of suitable environments at the landscape scale.Objectives
We investigated the impact of the landscape context on butterfly communities observed in residential gardens, taking into account garden characteristics, land-use types and presence of linear features in the surrounding landscape. We examined how species traits affected butterflies’ response to landscape context and habitat quality.Methods
We performed a cross-scale study, based on citizen science data documenting butterfly species composition and abundance in 920 gardens across France. We examined the effect of garden quality, the area of different land-use types and the length of linear elements measured at three scales within the surrounding landscape. Species were grouped according to their habitat preference and mobility.Results
Urbanization negatively affected total species richness and the abundance of butterfly in each group. This was related to declining habitat quality and reduced area of suitable habitat in the surrounding landscape. The magnitude of this effect, however, was negatively correlated with mobility, a trait related to habitat preference. The spatial scale at which landscape context best explained variation in butterfly abundance changed with species’ habitat preference.Conclusions
This study highlights the importance of preserving high quality habitats in altered landscapes and considering species’ mobility and habitat preference when assessing the impact of landscapes on butterfly communities.15.
In densely urbanized areas, small pockets of vegetated areas such as street verges, vacant lots, and walls can be rich in biodiversity. In spite of their small size, these ‘informal urban greenspaces’ can provide critical ecosystem services to urban residents. Maintaining and enhancing the provisioning of ecosystem services requires a systematic understanding of biodiversity patterns and drivers in informal urban green spaces. The ‘environmental filtering’ (a process of certain species selected by specific environmental conditions) concept in community ecology theory may serve as a useful tool for this goal. We tested a multi-scale filtering framework by examining the spontaneous plant diversity patterns (from 83 surveyed sites) on the vertical surfaces of the ancient city wall of Nanjing, China. We found that the variables representing local-habitat filtering (e.g., wall substrates and aspect) and landscape filtering (including spatial configuration of urban land cover, and nighttime light intensity surrounding the local habitats) can jointly explain substantial fractions of variations in taxonomic diversity (up to ca. 60%) and functional diversity (up to ca. 40%). The explanatory power was stronger in the repaired wall habitats than in the unrepaired counterparts, in line with the prediction that environmental filtering is more pronounced during the early stages of community assembly. While the strength of landscape filtering showed clear scale-dependency, its relative importance consistently outweighs local-habitat filtering across all study scales of 200–1600 m, suggesting that configuration of neighboring landscape context can play an important role in shaping local-scale biodiversity of informal urban green spaces. Our results have useful implications for the study, design, and management of informal urban green spaces. Well-tailored multi-scale filtering frameworks may contribute to understanding urban biodiversity patterns in a systematic way. 相似文献

Conserving urban biodiversity is often promoted as a ‘win-win’ nature-based solution that can help align public health and biodiversity conservation agendas. Yet, research on the relationship between biodiversity and psychological well-being reveals inconsistent and complex results. This body of research is also restricted to a few socio-cultural and environmental contexts and tends to ignore differences in individual characteristics, such as nature relatedness (i.e., emotional affinity to nature) and ecological knowledge, that can influence people’s experience of biodiversity. The aim of this interdisciplinary research is to explore the relationships between biodiversity and psychological well-being, and test the moderating effect of nature relatedness and ecological knowledge on these relationships. An ecological survey was conducted in 24 small urban gardens in Israel to measure the richness and abundance of birds, butterflies and plants, as well as land cover characteristics. In parallel, a social survey (close-ended questionnaires) was conducted in-situ to measure psychological well-being, nature relatedness, ecological knowledge, perceived species richness and socio-demographic variables. Psychological well-being measures were mostly associated with the cover of woody species, perceived species richness, and to a lesser extent, with actual species richness and abundance, for all taxa. Nature relatedness moderated these relationships. Respondents with high nature relatedness demonstrated positive well-being-richness relationships, while those with intermediate, or low nature relatedness showed no, or even negative relationships, respectively. Opposite relationships were recorded for bird abundance. Overall, individuals demonstrated poor ecological knowledge and this variable moderated only few relations between well-being measures, perceived butterfly richness and bird abundance. Our results demonstrate that one-size-does-not-fit-all when considering the relationship between psychological well-being and biodiversity, and that affinity to nature is a key moderator for this relationship. Designing urban green spaces that provide inclusive and meaningful nature experiences and foster emotional affinity to nature, is therefore key to aligning ecological and social objectives for sustainable urban planning. 相似文献

Among the different urban green spaces, wastelands are valuable spaces for conserving urban biodiversity. By hosting wild and spontaneous vegetation, wastelands can promote the contact citizens have with nature. However, lack of regular management can lead to negative perceptions. In this study we assessed perceptions, valuations and uses of wastelands by residents in two cities in the centre of France. We tested whether preferences for wastelands depended on where wastelands were located in the city, plant community characteristics or resident characteristics. The study investigated 18 wastelands, in three successional stages (initial grassland, intermediate grassland and shrubbery stages) and located in three categories of distance from the city centre (downtown, suburban, periurban). Vegetation was sampled in each wasteland and several plant community metrics were calculated. A total of 72 residents (4 per wasteland) living in the vicinity of the wastelands were interviewed about their use, valuations and perceptions of wastelands. Based on qualitative and quantitative analyses, the results highlighted that a significant proportion of residents (36%) conducted various activities in wastelands and that perceptions and valuations of wastelands were diverse, ranging from either negative (when wastelands were perceived as wild or abandoned areas) or positive (when wastelands were considered as natural and recreational). Valuations strongly depended on the successional stage, with intermediate grassland-like wastelands being preferred. We found no effect of wasteland location in the city, whereas resident characteristics (age and gender) marginally influenced valuations. This study provides new insights into the determinants of perception and valuations of urban wastelands. Particularly, we suggest that intermediate grassland-like wastelands could be easily integrated into urban planning both for recreational activities and conserving biodiversity. Alternatively, awareness of the value of initial grassland-like and shrubbery wastelands should be raised to improve their acceptability. 相似文献

With the stay at home orders during the pandemic, the often semi-public green spaces of the residential environment, usually created during the building of the houses, became our literal spheres of experience. In our study, we explored use and perceptions of local greenery by residents after sixteen months of the COVID-19 crisis, using face to face questionnaires in eight socially disadvantaged neighborhoods of Berlin, all exposed to high loads of environmental stressors and belonging to four relevant building types of Central European cities. Residential greenery was highly appreciated by residents during COVID-19, and fostered a more active appropriation such as meeting neighbors to reduce the sense of loneliness, doing sports and co-creating refugia in challenging times (e.g. greened balconies). Having children or doing home office/schooling encouraged people to use the green in front of the door in more active ways, such as gardening or even during winter. A minor proportion of respondents reduced contacts mainly due to fear of infections, underlining the need to overcome those distances and to re-connect neighbors and living inside and outside the houses in a post-pandemic city. Our data prove the functionality of residential greenery as ‘social tissue’ or ‘social hubs’ of neighborhoods by fostering attachment to place and people and, at the same time, as healthy environment for practices such as enjoying nature and physical activity in fresh air. 相似文献

Multi-functional landscapes in semi arid environments: implications for biodiversity and ecosystem services 总被引：4，自引：2，他引：2

Synergies between biodiversity conservation objectives and ecosystem service management were investigated in the Succulent Karoo biome (83,000 km2) of South Africa, a recognised biodiversity hotspot. Our study complemented a previous biodiversity assessment with an ecosystem service assessment. Stakeholder engagement and expert consultation focussed our investigations on surface water, ground water, grazing and tourism as the key services in this region. The key ecosystem services and service hotspots were modelled and mapped. The congruence between these services, and between biodiversity priorities and ecosystem service priorities, were assessed and considered in relation to known threats. Generally low levels of overlap were found between these ecosystem services, with the exception of surface and ground water which had an 80% overlap. The overlap between ecosystem service hotspots and individual biodiversity priority areas was generally low. Four of the seven priority areas assessed have more than 20% of their areas classified as important for services. In specific cases, particular service levels could be used to justify the management of a specific biodiversity priority area for conservation. Adopting a biome scale hotspot approach to assessing service supply highlighted key management areas. However, it underplayed local level dependence on particular services, not effectively capturing the welfare implications associated with diminishing and limited service provision. We conclude that regional scale (biome level) approaches need to be combined with local level investigations (municipal level). Given the regional heterogeneity and varied nature of the impacts of drivers and threats, diverse approaches are required to steer land management towards sustainable multifunctional landscape strategies. 相似文献

Biodiversity in urban and suburban environments can be supported through establishment of low maintenance-requiring herbaceous vegetation types. Here, we attempt to provide a perspective on the possibilities and limitations of establishing forb-dominated vegetation to support local biodiversity and contribute to changing public aesthetics concerning green spaces. Plant ecological theories, methods and experiences are the foundation for the design and establishment of such vegetation types. We emphasise the importance of high plant density and recurrent disturbance for the maintenance of forb communities. Well-established ecological theory tells us that totally self-sustaining herbaceous vegetation is not a realistic possibility. Without intervention, herbaceous vegetation will change over time and eventually be colonized by woody species through the process of succession. However, by applying a creative and strategic approach to establishment and subsequent management involving small scale disturbances, rather than solely a uniform maintenance regime, it may be possible to maintain a colourful, aesthetically appealing and species-rich forb dominated community that will support biodiversity and increase public acceptance of alternatives to conventional lawns in urban and suburban environments. 相似文献
