This volume brings together papers from geotechnical and civil engineers, biologists, ecologists, and foresters who discuss current problems in slope stability research and how to address those problems using ground bio- and eco-engineering techniques. Studies on slope instability, erosion, soil hydrology, mountain ecology, land use and restoration and how to mitigate these problems using vegetation are presented by both scientists and practitioners. The papers encompass many aspects of this multidisciplinary subject. For instance, geotechnical engineers, hydrologists, and plant biologists discuss the interaction between substrate movement while engineers, biologists, and foresters present technical and modeling methods. Coverage also includes the mechanisms and modeling of root reinforcement and the development of decision support systems, areas where significant advances have been made in recent years.
