Spanish forest ecophysiologists met in Espejo (Alava, Basque Country) in the I Spring Colloqium on Forest Ecophysiology. This Colloquium was designed according to the model of The Katalapi Summer Colloquia, which have been held at Parque Katalapi (Región de los Lagos, Chile) for the last 6 years. More than 60 researcher and students from Spanish universities and research institutes attended the event. Dr Luis J Corcuera, Reserach Director of Parque Katalapi also attended the meeting. The Colloquium was organized by Dr José Ignacio García-Plazaola (Universidad del País Vasco) and Dr Jaume Flexas (Universidad de las Islas Baleares). The importance of this meeting is that this is the first time that Spanish forest ecophysiologists meet by themselvesin Spain.
