The history and future of the restoration efforts at the hypereutrophic southern Finnish lake, Tuusulanjärvi, are
investigated. The interdisciplinary study is conducted within a modified DPSIR- framework, which allows us to
both trace back and envision the future of the dynamics of the complex socio-ecological processes involved in
restoration. The study covers the time period from the early 1970s up to 2030. The longitudinal study integrates
environmental historical, limnological, and futures studies. The analyses reveal the multiple time scales of social
and ecological processes present in long term restoration, the changing perceptions of and emphasis on restoration goals and outcomes over time, and the challenges that incidental and uncertain parameters, such as
weather conditions, pose to sustainable and efficient restoration endeavors.
