Studies on the effects of shoreline modifications (e.g. seawall, breakwaters, groynes) on marine biodiversity have shown they are not effective substitutes for natural habitats. To mitigate the negative effects of coastal urbanization on the marine community, and to increase biodiversity on these man-made habitats, eco-engineering methods such as enhancement units have been shown to be successful in increasing biodiversity on coastal armour. However, only recently have research groups taken the next step towards working with local government to install their enhancement units at larger scales and in public-access areas. As these enhancements encroach into common use spaces, it is necessary to engage the public to assess their support for future installations.In Chapter 1 I focus on the assessment of Singapore's public attitude towards eco-engineering enhancements through the dissemination of a questionnaire-based survey that quantified the public's knowledge and interest in local biodiversity as well as the perception and acceptance of seawall enhancements. The majority of those surveyed were supportive of installing these enhancements in coastal areas of Singapore and making them accessible to the public. In addition, many acknowledged the need for proper management and policing of public interaction with future eco-engineering installations. The public were keen for marine education and more nature spaces and biodiversity enhancements units can contribute to this need.With the positive reception regarding seawall enhancements received from the public in Chapter 1, it should be feasible to extend the use of these seawall enhancements in other similarly modified habitats. The majority of aquatic eco-engineering studies to date have been focused on exclusively marine and freshwater habitats, but the ecology of urban transitional habitats between the two has mostly been overlooked. It is important to investigate the need and feasibility of installing enhancement units in these transitional habitats. Towards this end, in Chapter 2 I characterized accessible urban transitional waterways found in Singapore. Abiotic parameters and canal profiles were recorded, and biotic samples were collected from each site along a 60 m transect from the coastal mouth of the waterway. I found that the community assemblages in each site were driven by relationships with sitespecific physical and abiotic factors. Each site varied in sedimentation, flow rate and dissolved oxygen, and this may affect local species recruitment. Transitional waterways require a bespoke management approach, suggesting that enhancement units used in transitional waterways need to cater to the drivers of each waterway.
