The Krycklan Catchment

Krycklan is a watershed located in the boreal region of northern Sweden in the county of Västerbotten. Krycklan is a tributary to the national River Vindelälven which starts in the mountain range, crosses Sweden and enters the Baltic Sea near Umeå.

Krycklan is a 6780 ha watershed catchment running through a mosaic of wetland and lakes that are interspersed throughout the forest landscape. The catchment area is partly located within the Svartberget experimental forests (in Swedish) which was established in 1920th by the Swedish forestry service and is today a unit of the Swedish University of Agricultural Science.

Krycklan History

Hydrology and biogeochemical cycling was initiated by Kaj Rosen and Harald Grip in the 1980´s and the monitoring of the 50 ha Nyänget catchment started.

During the 1990´s Nyänget contributed to the role of acid deposition on streams and Kevin Bishop and colleagues, opened for new views about anthropogenic acidification and natural acidity in boreal watersheds. This work has developed the present environmental guidelines for acidification in Sweden.

With time the scope of research has expanded to also include mercury, weathering, aluminum, carbon cycling and water uptake by trees. More intensive work also began on the connection between soils and surface waters which led to a more process-based understanding of the regulation of stream water chemistry.

The soil-frost experiment during winter

Another still growing research topic is the influence of climate on biogeochemistry and aquatic ecology which led to the expansion of 50 ha Nyänget catchment to the 6780 ha Krycklan catchment Study. The expansion was launched during the winter 2002/2003 and several stream further down from the Nyänget catchment were added into the sampling program which then covered the size of regional landscape scale.

Another stream, located at the Degerö Stormyr (Kulbäcksliden) complex was also included in the program. Additional, new instruments and logger equipment were installed at the different streams. The expansion has opened for the opportunity to broadening both the fundamental research questions and the water management issues, questions both asked by governments and researches to be answered.

Rödånäs, autumn 2011

Being able to work with Krycklan at a landscape scale allows us to apply environmental problems and models used for water managements and aquatic ecosystems protections. Addressing such questions would not be possible with information from plots, hill slopes and small catchments. These examples of smaller scales are however very important for the fundamental research, issues also addressed within Krycklans smaller catchments, like Nyänget where 30 years of continually measured stream water data soon exists.

Research

To date, several professors, researchers, assistant professors, almost 20 Ph.D, technicians, master students and field and lab assistants daily perform work connected to Krycklan.

Midsummer night at first order stream in Krycklan

The science taken place in Krycklan value the multidisciplinary approach which includes scale-dependent aspects but also bridge inferential gaps between varying catchment sizes, temporal dynamics, different landscape elements and the changes introduced by human perturbation.

V-shaped flume

Major science topics within the Krycklan Catchment Study

  • Connecting terrestrial and aquatic systems
  • Scaling from small to large streams
  • Human perturbation 

Krycklan makes it possible to understand key processes then used for building and developing models working at different scales

Digger on a clear-cut

KSC achieves state-of-the-art research because of the ability to use this unique research platform that span trough traditional disciplinary boundaries and linkages of empirical and experimental results. This makes it possible to understand processes then used for building and developing models working at different scales. We are also able to evaluate the results to overcome gaps between over-parameterized mechanistic models and over-simplified correlative approaches.

Collaborations and networks

KSC is a key for collaborations, the advantage is to apply Krycklan as a unique experimental platform for testing scientific and practical research questions in a natural environment.

Already initiated collaboration will launch modeling tools that will help predict the effects of human perturbations, such as those caused by forestry, climate change and long-range transport of air pollutants, along with forest biodiversity, forest economy optimization and water quality in forestry practice.

Svartberget and hence Krycklan is part of the Swedish Research infrastructure for Ecosystem Science 'SITES'
