Content: Soils and Landscape Restoration provides a multidisciplinary synthesis on the sustainable management and restoration of soils in various landscapes. The book presents applicable knowledge of above- and below-ground interactions and biome specific realizations along with in-depth investigations of particular soil degradation pathways. It focuses on severely degraded soils (e.g., eroded, salinized, mined) as well as the restoration of wetlands, grasslands and forests. The book addresses the need to bring together current perspectives on land degradation and restoration in soil science and restoration ecology to better incorporate soil-based information when restoration plans are formulated.

Note: Soils are fundamental to landscape protection / , Soil ecology and restoration science / , Sustaining forest soil quality and productivity / , Sustainable management of grassland soils / , Landscape degradation and restoration / , Soil recovery and reclamation of mined lands / , Salinity and the reclamation of salinized lands / , Biochar amendments show potential for restoration of degraded, contaminated, and infertile soils in agricultural and forested landscapes / , Bioremediation and soils / , Adaptive management of landscapes for climate change : how soils influence the assisted migration of plants / , Soils and restoration of forested landscapes / , Restoring fire to forests : contrasting the effects on soils of prescribed fire and wildfire / , Converting agricultural lands into heathlands : the relevance of soil processes / , Socioecological soil restoration in urban cultural landscapes /
