Water conservation initiatives seldom quantify the volume of water that is at stake in lawn watering. In many communities, including those in South Florida, outdoor water use, which includes lawn irrigation, is not metered separately from indoor water use and is indistinguishable from indoor water usage. A large number of residents use self supply non-potable wells for lawn irrigation that are not regulated by the South Florida Water Management District. The result is that residential lawn water use is difficult to account for and quantify. This thesis project addressed these difficulties by combining semistructured interviews, daily watering observations and irrigation system audits to ascertain how much public supply water and self supply (well) water was being used for residential lawn irrigation. The study also examined lawn watering practices and how factors such as: precipitation, the minimum plant needs of St. Augstinegrass, and how local watering restrictions influenced watering behavior. / by Felicia D.

Esta investigação caracteriza-se por ser estudo qualitativo que buscou compreender quais as características e as evidências da alfabetização científica presentes na ação educativa O Museu Vai à Praia, iniciativa desenvolvida pelo Museu de Astronomia e Ciências Afins (MAST) que leva atividades do museu para a praia durante o verão. Os dados deste estudo foram coletados durante o mês de março de 2013, no Rio de Janeiro e em três praias diferentes da cidade de Niterói, contemplando, além de entrevistas com os conceptores da ação educativa e com o público espontâneo, a observação da ação e a análise documental do projeto. A revisão da literatura referente à alfabetização científica e à educação em museus possibilitou o desenvolvimento de uma ferramenta de análise composta de dimensões e seus respectivos indicadores, usados para análise de dois importantes aspectos do O Museu Vai à Praia: as intenções do programa nos anos 1980 e em 2013 e a experiência do púbico na sua quinta edição. Os resultados revelam que, apesar de o projeto não ter sido elaborado na perspectiva da Alfabetização Científica (AC), ela contempla todas as dimensões propostas: Científica, Interface Ciência e Sociedade, Institucional e Afetiva, além da maioria dos indicadores de cada uma das dimensões. Mesmo nem todos os indicadores estando explicitados, consideramos que a presença reiterada de todas as dimensões denota que, desde sua origem, os objetivos da ação O Museu Vai à Praia dialogam com as finalidades da alfabetização científica. A ausência de alguns dos indicadores foi problematizada, assim como foram discutidas as mudanças nas ênfases de algumas dimensões ocorridas entre os anos 1980 e 2013, com a finalidade de promover uma análise crítica e uma reflexão sobre o papel da ação O Museu Vai à Praia na perspectiva da AC. Ao se defender que a AC é um processo que ocorre ao longo da vida, avaliamos que as ações educativas desenvolvidas pelos museus de ciências possuem grande potencial para sua promoção e que tais ações, se planejadas com base nas dimensões e nos indicadores propostos, podem se mostrar como um recurso fundamental para a maior compreensão da ciência e de sua relação com a sociedade. / This investigation is a qualitative study that aims to understand the evidences and characteristics of scientific literacy present in the project \"The Museum goes to the Beach\", an initiative developed by MAST (Museum of Astronomy and Science), which takes museum activities to the beach during summer.Data was collected in March 2013 in Rio de Janeiro and in three different beaches of Niteroi. Besides interviews with the creators of the project and the spontaneous public, we conducted a documental analysis and an observation of activities. The literature review on scientific literacy and education in museums allowed the development of an analytical tool regarding dimensions and indicators of \"the musem goes to the beach\" that focus on two specific aspects: the intention of the project in the 1980s and in 2013 and the experience with the participants in its fifth edition.Results indicate that even though the project was not built under the perspective of scientific literacy, it involves all the proposed dimensions: scientific, science and society interface, institutional and affective, besides the majority of indicators in each of the dimensions.Even though not all indicators are explicit, we believe that the consistent presence of all the dimensions reinforce that, since its origin, the objectives of \"the museum goes to the beach\" dialogue with the goals of scientific literacy.The absence of some indicators was analyzed, such as the change in emphasis in some dimensions between the 1980s and 2013 was discussed, in the attempt to foster a critical analysis and reflection over the role of the activity \"the museum goes to the beach\", under the perspective of scientific literacy.Stating that scientific education is a process ongoing throughout life, it is evaluated that educational activities developed by science museums have great potential to its promotion. This kind of activities, if based on the proposed dimensions and indicators, can be a fundamental resource to a deeper understanding of science and its relation with society.

Depuis sa fréquentation par les premiers curistes étrangers en 1820 jusqu’à l’édification du pont de Saint-Nazaire et de la Route Bleue en 1975, le paysage de la Côte de Jade a connu de profondes mutations. Terre inculte et délaissée à la fin du XVIIIe siècle, cette partie du littoral atlantique devient, dès les premières années du XIXe siècle, la destination privilégiée de baigneurs étrangers attirés par les bienfaits des eaux ferrugineuses et des bains de mer. Le charme pittoresque de ce paysage caractérisé par l’alternance de côtes escarpées et de longues étendues de sable fin sous un couvert de pins maritimes invite à l’évasion et au dépaysement. D’abord réservées à l’exigence d’une clientèle aristocratique et bourgeoise, les stations deviennent au milieu du XXe siècle le rendez-vous d’un tourisme de masse et la silhouette de la côte est profondément modifiée. Ces villes de bord de mer sont le reflet des grandes mutations de la société et répondent à des contraintes fonctionnelles, morphologiques et idéologiques liées à leur implantation géographique et à leur époque. L’habitat balnéaire, représentatif des goûts de son propriétaire et de l’enthousiasme croissant des maîtres d’œuvre pour cette nouvelle architecture saisonnière, consacrée au repos et aux loisirs, est conditionné par la présence de la mer puis du soleil. Malgré la diffusion de modèles de construction dans les catalogues d’architecture, la liberté d’interprétation de ces programmes crée une importante diversité stylistique, spécifique à l’architecture balnéaire. / Between the time that it was first frequented by foreign visitors taking the waters for their health in 1820 and the building of Saint Nazaire’s bridge and the Blue Road in 1975, the landscape of the Jade Coast has undergone significant changes. On virgin coastline that had been left undeveloped at the end of the 18th century, this part of the Atlantic coast became a favourite destination for foreign bathers in the early years of the 19th century, attracted by the benefits of chalybeate spring waters and the chance to bathe in the sea. The picturesque charm of this varied landscape, with its steep coast mixed with long sandy beaches and pine trees, was an invitation to enjoy an escape and a change of scenery. Having been initially devoted to the demands of an aristocratic and middle class clientele, seaside resorts became, in the middle of the twentieth century, the meeting place for large numbers of tourists and consequently the form of the coastline has been modified substantially. These seaside resorts reflect the profound changes to our society, and as well as being constrained by function, morphology and ideology, they are responses to their geographical location and to their date. Seaside housing reflects the taste of owners and a growing enthusiasm among developers for this new seasonal architecture dedicated to relaxation and leisure, architecture conditioned by the presence of the sea and the sun. Despite the spread of building models through architectural catalogues, the variety of interpretation of these models creates a broad stylistic diversity, which is specific to seaside resort architecture.

A quoi sert la responsabilité contractuelle ? « Réparer » répond la doctrine classique. « Payer ! » conteste un courant doctrinal audacieux. « Punir ? » s’interrogent quelques voix ici et là. La responsabilité contractuelle cherche à reconstituer une situation à l’image de celle qui aurait découlé de l’exécution du contrat. Ce faisant, elle ne remplit pas une fonction unique mais plusieurs fonctions. Elle est d’abord tournée vers le créancier, auquel elle offre un substitut en argent de l’exécution elle-même (fonction de paiement) et la compensation des préjudices consécutifs à l’inexécution (fonction de réparation). Les dommages et intérêts en lieu et place de l’exécution et les dommages et intérêts compensatoires se complètent et permettent le rétablissement du créancier. La responsabilité contractuelle est ensuite tournée vers le débiteur : elle punit l’inexécution d’une particulière gravité en le condamnant à verser une somme supérieure à celle due au titre du paiement et de la réparation (fonction de peine privée). Cette punition peut notamment prendre la forme d’une restitution des profits, sanction de portée générale de la violation lucrative du contrat. L’étude des fonctions de paiement, de réparation et de peine privée révèle le caractère hybride de la responsabilité contractuelle, lequel forge sa spécificité et fonde son autonomie. Des fonctions qui sont reconnues à la responsabilité contractuelle dépendent directement les conditions qui président à sa mise en oeuvre, les effets qui sont les siens, la place qu’elle occupe au sein du droit de l’inexécution, son articulation avec les autres sanctions et la frontière qui la sépare de la responsabilité délictuelle. Cette étude de droit comparé, qui inclut, aux côtés du droit français, les droits allemand et anglais, examine les interactions entre les fonctions et les sanctions de la responsabilité contractuelle en vue d’une meilleure compréhension et d’une possible reconstruction de cette institution. / What is the purpose of contractual liability? “To compensate” will be the classical answer. “To provide a substitute for performance!” will dissent some daring scholars. “To punish?” will ask some voices here and there. Contractual liability aims at reproducing a situation similar to the one that would have resulted from performance. In doing so, it fulfils not one, but several functions. Firstly, looking at the creditor, contractual liability offers him a monetary substitute for performance itself (satisfactory function) and a compensation for the consequential loss suffered due to the breach of contract (compensatory function). Secondly, turning to the debtor, contractual liability punishes particularly serious breaches of contract by allowing an amount of damages greater than the cost of performance and compensation (punitive function). In case of a profit-oriented breach, this punishment can take the form of an account of profits. The clarification of these three functions reveals the hybrid nature of contractual liability that forges its specificity and provides the conceptual foundations for its autonomy. On these functions depend the conditions and effects of contractual liability, its place in contract law and its articulation and combination with the other remedies for breach of contract, as well as its borderline to tortious liability. This comparative work in French, German and English Law examines the interactions between the functions and the sanctions within contractual liability in view of a better understanding and a possible rational reconstruction of the concept of contractual liability.

Lagoas costeiras são ecossistemas cruciais para conservação da biodiversidade local e global. O sistema do rio Tramandaí (SRT) apresenta uma série de lagoas costeiras rasas conectadas por canais naturais, e uma saída, via estuário de Tramandaí, para o oceano. Esse sistema é dividido em dois subsistemas, ao norte e ao sul do estuário, resultado de padrões hidrodinâmicos e da influência do vento e que definem características ambientais distintas a esses subsistemas. Um gradiente decrescente, de norte a sul, no estado trófico dessas lagoas já foi verificado. No presente estudo é testada hipótese de variabilidade espacial (lagoas e subsistemas) e temporal (estações do ano) na magnitude de variáveis abióticas e de descritores ecológicos das assembleias de peixes (composição, riqueza, diversidade, dominância) do SRT. Também é avaliada a relação entre variáveis abióticas e descritores das assembleias nesses subsistemas. É comparada a seletividade de captura de um amostrador ativo (rede de arrasto de praia) e de um amostrador passivo (redes de emalhe). Amostragens foram conduzidas de novembro de 2008 a abril de 2010 com rede de arrasto de praia e redes de emalhe, na zona litoral das lagoas Itapeva, Quadros e Malvas no subsistema norte, e nas lagoas Fortaleza, Rondinha e Barros no subsistema sul. Entre abril de 2009 e março de 2010, amostras de água foram coletadas e dez variáveis foram mensuradas em laboratório. Análises de ordenação (NMDS) mostraram clara diferença de composição, abundância numérica (CPUEn) e em biomassa (CPUEb) de espécies entre amostradores. A análises de ANOSIM e SIMPER mostraram baixa similaridade desses parâmetros entre amostradores. Houve diferença no tamanho dos peixes coletados com redes de arrasto e emalhe. Turbidez e DBO5 tiveram médias superiores no subsistema norte, enquanto que condutividade, salinidade, dureza, sólidos totais dissolvidos e transparência de Secchi no subsistema sul. Temporalmente foram verificadas diferenças de temperatura, pH, salinidade, turbidez, dureza, sólidos totais dissolvidos, oxigênio dissolvido, sólidos suspensos e profundidade, mas somente os dados de pH, condutividade, turbidez e DBO5 mostraram interação entre os fatores espaço e tempo. As assembleias das margens rasas da zona litoral foram dominadas por dez espécies, resultando em alta similaridade de composição, CPUEn e CPUEb entre os subsistemas. A riqueza de espécies variou espacial e temporalmente. Diversidade e equitabilidade espacialmente, e CPUEn e CPUEb temporalmente. As assembleias das regiões pelágicas da zona litoral foram dominadas por sete espécies, com dominância numérica das espécies L. anus e A. aff. fasciatus no subsistema norte. A NMDS mostrou similaridades maiores de composição, CPUEn e CPUEb entre amostras de um mesmo subsistema, no entanto, a ANOSIM não apresentou resultados significativos para rejeição das hipóteses nulas. CPUE n e b, diversidade e equitabilidade variaram espacialmente, enquanto a riqueza, temporalmente. A análise de correlação canônica (CCA) mostrou que temperatura, DBO5, sólidos suspensos e dureza responderam por 46% da variabilidade dos dados de abundância numérica das espécies. Os resultados sugerem que amostradores ativos e passivos reproduzem diferentes imagens da assembleia por eles amostrada, indicando que o delineamento amostral para estudos com peixes nesses ecossistemas deve contemplar tais diferenças. As diferenças ambientais dos subsistemas refletem em diferenças na qualidade da água e os resultados obtidos confirmam os pressupostos do gradiente trófico. A estrutura das assembleias de peixes foi mais variável em resposta as condições ambientais em escala espacial, enquanto que temporalmente, houve maior coerência na variabilidade dos dados. As relações das espécies com as variáveis ambientais são discutidas com base no comportamento alimentar e/ou reprodutivo das mesmas e na qualidade do habitat. Tais resultados podem ser úteis como subsídio a elaboração de estudos de manejo costeiro do SRT, sobretudo com relação aos recursos pesqueiros, e na proposição de modelos de estrutura das assembleias de peixes de lagoas costeiras subtropicais. / Coastal lakes ecosystems are crucial for conserving biodiversity both locally and globally. The river Tramandaí system (SRT) comprises a series of shallow coastal lagoons, connected by natural channels, and has an output via Tramandaí estuary into the ocean. This system is divided into two subsystems, north and south of the Tramandaí estuary, as result of hydrodynamic patterns, influence of wind and environmental characteristics that define the subsystems. A trophic gradient decreasing from north to south in those lagoons was identified. In this study is tested the hypothesis of spatial (lagoons and subsystems) and temporal (seasons) variabilities in the amplitude of abiotic variables and descriptors of the fish assemblages (species composition, richness, diversity, dominance) in the SRT. It also assessed the relationship between abiotic variables and descriptors of the fish assemblages in these subsystems. Is compared the selectivity of the active fishing (beach seining) and passive (gill netting) fishing. Sampling was conducted from November 2008 to April 2010 with beach seine and gill nets in the littoral zone of lakes Itapeva, Quadros and Malvas in north subsystem, and Fortaleza, Rondinha and Barros lakes, in south subsystem. Between April 2009 and March 2010 water samples were collected and ten variables were measured in the laboratory. Analyses of ordination (NMDS) showed clear differences in composition, numerical abundance (CPUEn) and biomass (CPUEb) of species between samplers. The analysis of similarity (ANOSIM and SIMPER) showed low similarity of these parameters between nets. There was a difference in the size of the fish caught with beach seine and gill nets. Turbidity and BOD5 averages were higher in the northern subsystem, while the conductivity, salinity, hardness, total dissolved solids and Secchi transparency in the south subsystem. Temporally were observed differences in temperature, pH, salinity, turbidity, hardness, total dissolved solids, dissolved oxygen, suspended solids and depth, but only the data for pH, conductivity, turbidity, BOD5 showed interaction between the factors space and time. The assemblages of the shallow margins of the coastal zone were dominated by ten species resulting in high similarity of composition, CPUEn and CPUEb between subsystems. Species richness varied spatially and temporally, while diversity and evenness only spatially and CPUEn and CPUEb only temporally. The assemblages of the pelagic regions of the coastal zone were dominated by seven species with numerical dominance of L. anus and A. aff. fasciatus in north subsystem. The NMDS showed greatest similarity in composition, CPUEn and CPUEb between samples of the same subsystem, the ANOSIM however, showed no significant results for rejection of the null hypothesis. CPUE n and b, diversity and equitability varied between lakes and subsystems, while the richness between seasons. The canonical correlation analysis (CCA) showed that four variables (temperature, BOD, suspended solids and hardness) account for 46% of data variability of species abundance. Samples of the north subsystem were directly influenced by temperature, BOD and suspended solids while the south subsystem by the hardness. The results suggest that active and passive samplers reproduce different images of the assemblage sampled and indicate that the sampling design for studies of these ecosystems should include such differences. The environmental differences in subsystems reflect in water quality differences and the results confirm the assumptions of a trophic gradient decreasing from north to south in the SRT. The structure of the fish assemblages was more variable in response to environmental conditions in spatial scale between subsystems, while there was greater consistency in the temporal variability of the data. The relationships between the species and environmental variables are discussed based on the feeding behavior and / or reproduction of the same and by habitat quality. These results may be useful as an aid to preparing studies of coastal management of SRT, especially with respect to fisheries, and in proposing models of the structure of the fish assemblages of subtropical coastal lagoons.

This thesis investigates the effectiveness of Low Impact Development Infrastructure (LIDI) and Green Infrastructure (GI) in reducing flooding resulting from heavy rainfall events and sea-level rise, and in improving stormwater quality in the City of Miami Beach (CMB). InfoSWMM was used to simulate the 5, 10, and 100-year, 24-hour storm events, total suspended solids (TSS), biochemical oxygen demand (BOD), and chemical oxygen demand (COD) loadings, and in evaluating the potential of selected LIDI and GI solutions in North Shore neighborhood. Post-development results revealed a decrease of 48%, 46%, and 39% in runoff, a decrease of 57%, 60%, and 62% in TSS, a decrease of 82%, 82%, and 84% in BOD, and a decrease of 69%, 69%, and 70% in COD loadings. SWMM 5.1 was also used to simulate the king tide effect in a cross section in Indian Creek Drive. The proposed design simulations successfully demonstrated the potential to control flooding, showing that innovative technologies offer the city opportunities to cope with climate impacts. This study should be most helpful to the CMB to support its management of flooding under any adaptation scenarios that may possibly result from climate changes. Flooding could be again caused as a result of changes in inland flooding from precipitation patterns or from sea-level rise or both.

Les barres sableuses pré-littorales ont un rôle fondamental en morphodynamique des plages soumises à l’action des vagues. Le déséquilibre permanent entre les flux sédimentaires induits vers laplage par les non linéarités des vagues et ceux induits vers le large par le courant de retour gouverne lamigration transversale des barres. Dans cette thèse, un nouveau modèle morphodynamique de profilde plage intégrant l’état de l’art des processus hydro-sédimentaires a été développé. Le faible coûten temps de calcul de ce modèle permet de réaliser des simulations à long terme, O(mois/années),de la morphologie de plages réelles ayant des caractéristiques variées (pente, type de déferlement,granularité). La simulation sur plusieurs jeux de données, de plages réelles et expérimentales, a permisd’identifier la contribution respective des principaux processus hydro-sedimentaires dans la dynamiquede la plage suivant les conditions de houle (e.g. Tempête, temps calme). Ces avancées scientifiques ontété intégrées à un modèle 2DH, ce qui a notamment permis de simuler pour la première fois sur des casacadémiques la formation d’une barre sableuse rectiligne à partir d’une plage parfaitement plane, suiviedu développement de corps sableux tridimensionnels. Ces résultats ouvrent la voie vers l’applicationde ce type de modèle aux plages naturelles soumises à une large variabilité de régimes de houle. / Sandbars are ubiquitous patterns along wave-dominated sandy coastlines and are key elementsin the global evolution of beaches. Cross-shore sandbar migrations are the result of the permanentimbalance between sediment flux driven by wave non-linearity and mean return current. In this thesis,we developed a new process-based beach profile model integrating the recent scientific advancesin term of hydrodynamics and sediment transport developed for beach morphodynamics. The lowcomputing time allows for long-term morphodynamic simulations (O months/years) of natural beachprofiles of diverse characteristics (beach slope, sediment grain size or type of wave breaking). Modelvalidations on several data sets, encompassing natural and experimental beach profile evolutions,highlight the respective contribution of the main hydrodynamic and sediment transport processesinvolved in specific cross-shore sandbar evolution relative to various wave conditions. Finally, all thecross-shore physical processes were integrated in a 2DH morphodynamic model, resulting for the firsttime in the simulation of a quasi-complete down state sequence showing alongshore bar generationwith subsequent spontaneous formation of transverse bar and rip morphology. These very encouragingresults pave the way for using this model to simulate 3-Dimensional evolutions of natural beachesforced by irregular wave conditions

The 2004 Indian Ocean and 2011 Tohoku tsunami events have shown the destructive power of tsunami inundation to the constructed environment in addition to the tragic loss of life. A comparable event is expected for the Cascadia Subduction Zone (CSZ) which will impact the west coast of North America. Research efforts have focused on understanding and predicting the hazard to mitigate potential impacts. This thesis presents two manuscripts which pertain to estimating infrastructure damage and determining design loads of tsunami inundation. The first manuscript estimates damage to buildings and economic loss for Seaside, Oregon, for CSZ events ranging from 3 to 25 m of slip along the entire fault. The analysis provides a community scale estimate of the hazard with calculations performed at the parcel level. Hydrodynamic results are obtained from the numerical model MOST and damage estimates are based on fragility curves from the recent literature. Seaside is located on low lying coastal land which makes it particularly sensitive to the magnitude of the events. For the range of events modeled, the percentage of building within the inundation zone ranges from 9 to 88%, with average economic losses ranging from $2 million to $1.2 billion. The second manuscript introduces a new tsunami inundation model based on the concept of an energy grade line to estimate the hydrodynamic quantities of maximum flow depth, velocity, and momentum flux between the shoreline and extent of inundation along a 1D transect. Using the numerical model FUNWAVE empirical relations were derived to tune the model. For simple bi-linear beaches the average error for the tuned model in flow depth, velocity, and momentum flux were 10, 23, and 10%, respectively; and for complex bathymetry at Rockaway Beach, Oregon, without recalibration, the errors were 14, 44, and 14% for flow depth, velocity, and momentum flux, respectively. / Graduation date: 2013

Four of the composers of the Second New England School, Amy Cheney Beach (1867-1944), Arthur Foote (1853-1937), George Whitefield Chadwick (1854-1931), and Horatio Parker (1863-1919), led the flowering of America's art music in the late nineteenth and early twentieth centuries. This study focused on these composers' partsongs that contain an original piano part and also on one chamber work with piano by each of them. The role of pianism within these works was the primary topic of this study, and the piano's contribution to the partsongs and the chamber works was compared and contrasted.The study centered on the four composers' compositional techniques, and the relationship between the voices or strings to the piano was identified. It also revealed the technical demands placed on the pianist. Each partsong or chamber work movement was first briefly analyzed and then suggestions to the pianist/ensemble were made, which were based on the analysis, and that intended to draw the pianist's attention to the most relevant concerns that he will face while preparing this music. The works that I included in this study are from the first period of American history in which American composers wrote significant pieces of art music. The compositions from this turning point in American history reveal a fascinating mix between German Romantic, Modernist, and "American" elements. I found both the partsongs and chamber pieces to be worthy of study, and the large body of works of these four composers, in my opinion, deserves greater exposure.The piano writing, in both their partsongs and chamber works, is quite accomplished and reveals just how gifted these four composers were as pianists. The varied piano textures and the technical demands for the pianist create challenging, yet enjoyable interesting, piano parts, which serve both the partsongs and chamber pieces very well. The piano writing of these four composers' chamber pieces is more complex than that of their partsongs, but both genres contain effective piano parts. Contemporary audiences of classical music would find the piano writing of these works (not to mention the works in their entirety) to be very worthwhile. / School of Music

Traditionally New Zealand ecological research has focused on nature outside of cities, however, as with global trends, there is now more interest being given to the ecological functioning of cities and the potential they may hold for protecting native biodiversity. Traditionally, efforts to maintain biodiversity in urban areas have been restricted to remnants of native vegetation and restoration activities. Little attention has been given to how native biodiversity could be woven into the urban fabric in an ecologically meaningful way. One option, that is receiving much attention overseas, is to recruit underutilised urban spaces such as wasteland. A subset of urban wasteland, abandoned industrial areas usually awaiting development and other areas such as the railway buffer, are referred to here as greyfield. These are ephemeral sites that may sit between uses for as little as a few months to many years. Overseas, particularly in European countries, these have been recognised as important habitat for both native and introduced plant species. In New Zealand cities these support primarily introduced plants and their contribution to native biodiversity has been unknown. This thesis took an interdisciplinary approach to the question of whether urban greyfields might have potential value as biodiversity protection and conservation opportunity. Ecological methods were combined with an assessment of the planning framework to answer this question. iii Greyfields in Christchurch, New Zealand were surveyed to determine their current contribution to native biodiversity and whether they may act as urban analogues of natural habitats. Overseas research has shown that urban features such as pavements, walls and rooftops offer habitats analogous to cliffs and rocky habitats. Cities are therefore increasing the habitat exploitable by species whose natural habitats are geographically restricted. The Christchurch greyfields were assessed for their potential to act as analogues of four habitat types that have been categorised as historically rare in New Zealand: braided riverbeds, shingle beaches, rock outcrops and limestone outcrops. The findings suggest that urban greyfields, if managed appropriately, have the potential to support a wider range of native species Planning documents and biodiversity strategies written for Christchurch were assessed to see how well they facilitated non-traditional biodiversity enhancement initiatives, specifically the greyfield network for native biodiversity. A major finding here was a lack of information on how to enhance biodiversity where little of the natural features of the landscape were left and that this was creating a barrier to adopting more integrative approaches to enhancing native biodiversity. Finally, a plan to create a greyfield network for native biodiversity is proposed and suggestions are made as to minor changes to the planning framework that would more easily facilitate the uptake of novel biodiversity enhancement initiatives in the City.
