How do trees experience the four seasons? The artist Christina Della Giustina works with scientific long-term data from different forest plots in Switzerland collected by the scientists she is working with. The data are used to analyse the impact of environmental change on forest ecosystems. She turns them into light installations and sound performances.The live music performance at the Jazz Festival Montreux makes use of scientific data from a forest plot at Lac Leman, turning these ecophysiological processes driven by changing environmental conditions into a tangible, poetic experience.
