Release for Ekobank Gärdsmossen. A checkbook with documentation of the public and process-based artwork, from its coming into being on 15 September 1997 up until today. Conversation about the work, in situ in Gärdsås, Bergsjön, with an invited conversation partner. The ecological art process Ekobank Gärdsmossen, began on 15 September 1997, when ten logs of oak were dug down in the wetland Gärdmossen in Bergsjön, which had been restored at that same period. The logs of oak lay dug down at a depth of 4–5 meters in an anaerobic environment to develop with nature's own means, microbes, to become black oak. The process for oak logs to become black oak takes around 100 to 300 years. This process involves a transformation which maximises its value. The work shows the potential of long-term thinking, and what an ecologically sustainable process can create. This artwork is possibly Gothenburg’s most invisible, most anonymous and perhaps first ecological public artwork.
