Between 1982 and 1987, German Fluxus artist Joseph Beuys, with the help of volunteers, planted 7,000 oak trees in Kassel, Germany. Each tree was flanked by a stone, to provide nourishment for the soil around the tree as it eroded.
The project, subtitled “City Forestation Instead of City Administration,” was created for the 1982 international art exhibition Documenta 7, and the final tree was planted at the opening of Documenta 8 in 1987. Since then it has inspired similar works throughout the world.
