Combining the Aesthetic and Ecological Aspects of Man-Made Structures on Coastal Wetlands

Man-made structures are used as adaptive solutions to natural and urbanization stressors of coastal wetlands. These structures alter the wetland environment not only impacting ecological value and habitats but also landscape esthetics. A green structure approach aims to re-establish the natural functions of wetlands; however, landscape esthetics of the relationship between man-made structures is required that also should not be neglected. Physical structures are tangible and shape the visual environment, which can influence people’s esthetic preference. Pleasing scenery can arouse protective instincts and motivate public participation in wetland conservation. Man-made structures changed and limited landscape room, resulting in homogeneous environmental information in the landscape foreground, while hindering collection of environmental information from the background. The discordance of contextual cues between coastal wetlands and man-made structure affects the esthetics and preference of landscape. Therefore, consideration of both landscape esthetics and the ecological impact of man-made structures is an optimal coastal wetland restoration strategy. Here, a conceptual common ground between the visual and ecological aspects of man-made structures is proposed. This concept is applied to design man-made structures that will benefit landscape esthetics and mitigate wetland ecological impacts
