The biological drought and growth indicator network

Welcome to

We turn automatically measured stem radius changes of trees (in a micrometer resolution!) into growth patterns and drought stress indicators of forests in Switzerland and elsewhere.

Watch trees in your region growing, live! Did you know that tree stems shrink during the day and expand during the night and that trees grow mainly at night?

Quickviews from the last 7 days of all raw data measured within the network TreeNet. Shown here are stem radius change measurements detected by point dendrometers (three trees from the site Alvaneu and three trees from the site Bachtel). Klick on the image to browse the latest data.

Are there growth trends since 2011?

Are trees able to grow in periods of stem shrinkage?
