🌳 Want to watch trees grow?

Our DL-ZN1 dendrometers reveal: trees shrink by day, expand at night, and only grow on surprisingly few days per year. A #WSL study shows spruce, fir, and beech are growing less despite warmer springs. Less growth = less carbon stored.

#TreeNet tracks this across Swiss forests – using our DL-ZN1 dendrometers.

When the Forest Speaks 🌲
Trees grow mostly at night — a fascinating finding from #TreeNet,
Eidg. Forschungsanstalt für Wald, Schnee und Landschaft WSL, based on data from over 600 trees across Switzerland. Decentlab DL-ZN1 dendrometers record stem radius every ten minutes, revealing real-time insights into growth, water balance, and drought stress.
Sound artist Marcus Maeder transforms these signals into sound — making climate change not just visible, but audible.
