When does a tree’s sap start flowing, when do trees get to work in the morning, when does their trunk grow most? During one year, the artists of the Anaïs Berck collective measured the movements of three Scots Pines in three nature reserves in Flanders, with the intention of designing tree clocks. They recorded their movements using sensors that measure the expansion and contraction of the trunk, CO2 absorption, air temperature and humidity, and sunlight.

The installation runs simultaneously in Constant, the Kalmthoutse Heide/De Vroente, Landschap De Liereman, and Pijnven/National Park Bosland.
