U. glabra is a largely non-suckering tree of hedges, field-borders and streamsides, but also forms mixed or pure woodland, especially on limestone and other base-rich soils. It is also a colonist of ungrazed grassland, rocky ground and waste and spoil heaps, and is also planted. 0?530 m (Atholl, E. Perth).
In C. and S. England, U. glabra hybridises freely, especially with U. minor, and some intermediates may have been mis-recorded as U. glabra. Although more resistant to Dutch Elm disease than U. procera, most mature trees outside Scotland have now been killed. The native status of many records is questionable.
