STReESS: meta-data portal  

The COST Action FP1106 STReESS (“Studying Tree Responses to extreme Events: a SynthesiS) will form a platform to facilitate data exchange for a basic understanding of short to long-term physiological responses of trees to extreme climate conditions.

By filling the form below you will be included in the catalog giving you the chance to make the scientific community aware about your data and expertise. This will stimulate scientific exchange, new collaborations and unique research opportunities. Participation does not mean that your data will be freely accessible. We only expect you to submit basic meta-data information (e.g. what type of data do you have, for which species and for which area). Please repeat the database entry for every set of data. The catalog (without the personal data) will be public and continuously up-dated.

For inquiry or specific search from the catalog, please contact
