Fraxinus excelsior (Ash)
A deciduous tree of woodland, scrub and hedgerows, especially on moist, basic soils, but also frequent on rock scars and cliffs, stabilised scree and the grikes of limestone pavement. It can tolerate periodically waterlogged soils, being found around springs and in Alnus and Salix carr. In managed woodland it may be grown as a timber tree or coppice. It is a rapid coloniser of waste ground, disused quarries and railway banks. 0-585 m (Cwm Idwal, Caerns.).
The range of F. excelsior is stable. In N. Scotland it is native on limestone and widely planted elsewhere; differentiating native from alien populations can be difficult.
European Temperate element.
