Leaves of the tiny willow Salix polaris Wahlenberg from a lake deposit in northern Jylland have been dated to c. 14,300 cal. years BP. These are some of the oldest dated plant remains after the last deglaciation from an on-shore deposit in Denmark. Salix polaris was probably one of the first woody plants that immigrated to Denmark, where it played an important role on the raw, carbonate rich but unstable soils.
