Differentiation of soils and land use changes in the vicinity of the disappeared Gardeja lake (Northern Poland)

Abstract The aims of the study were to characterize shoreline soil development and evolution and to determine land use changes (19th to 20th centuries) in the direct catchment of the completely vanished Gardeja lake. The study was based on pedological research and analysis of cartographic materials. The main factor determining the current development of shoreline zone soil cover at the former Gardeja lake was human activity (lake dewatering, further drainage and human-induced erosion). Studied soil profiles were developed from mineral, non-lacustrine materials (upper parts of the slopes) and lacustrine sediments covered with colluvium. The analyzed soil catenas are representative for the undulated young glacial landscape of Northern Poland. The biggest changes of the land use were observed for the class of grasslands that is combined with shrubs (increase of cover area).
