Zusammenfassung
In the plains of the Tierra de Pinares (Segovia Province, Spain) remains a population of birch (Betula alba L.). These are the only birch trees on the plains of the Duero basin. There are a few groups of trees located on the banks of the Cega river, in a particular hidromorphological and topoecological position: the very tilt and unstable slopes of the little Cega canyon, and its walls from which groundwater flows out constantly.
