The visual appearance of hard surface covers used on many of Hong Kong’s 70,000 registered man-made slopes, has caused public concern over the last 20 years. The aim of this applied research study is to address this by identifying and defining alternative, visually appropriate, ecologically relevant and resilient green slope covers for soil and rock cut slopes, embankments and retaining walls in Hong Kong, and establishing best practice in their landscape treatment. The study continues and updates earlier research studies (1998-2000), and maintains its unique collaboration between landscape, ecological and geotechnical engineering expertise. The original research in this study comprises the detailed analysis of international case studies and best practice publications (in the USA, Europe and Australia), a critical literature review of scientific papers relating to planting on slopes and the influence of tree and shrubs on soil mechanics, an extensive review of archival records of the construction and maintenance records of, and the field assessment of (N>200) selected slopes to determine the efficacy of both hard and soft (planted) landscape treatments.
