Growing interest in the appearance of slopes in Hong Kong complements similar changes in the region and the profession at large. Recent developments in local slope landscaping and bio-engineering practice include employment of landscape architects on all Government slope projects and publication of new technical guidelines by the Geotechnical Engineering Office. Based on a review of papers submitted to the session, areas of interest and potential future development are discussed, with special reference to slopes in Hong Kong. These include the value of vegetation roots for different slope settings, use of native vegetation species and alternative forms of bio-engineering, purpose and specification of erosion control products, landscaping of hard surfaces and aesthetic aspects of slope 'infrastructure'.
