Ash

Ash (Fraxinus) is a member of the olive family, the Oleaceae. There are three species native to western Europe: the common ash (Fraxinus excelsior), the narrow-leaved ash (Fraxinus angustifolia) and the manna ash (Fraxinus ornus). In Britain and Sweden FRAXIGEN is working only with common ash, while the research in Greece and Spain is focused on the other two species, which are native to southern Europe.
This section offers general information on these three species ash species, regarding their distribution, ecology and habitat and a simple guide to distinguish them in the field.
