Ash is the commonest tree in Irish hedgerows, and is also a traditional woodland species. It will grow in a range of soils, not acid, and prefers well-drained sites.

Ash woods are found in the Burren, Co Clare, and Hanging Rock in South Fermanagh.

The flowers are very dark, almost black, and may be seen before the leaves develop – ash is one of the last trees to come into leaf and is one of the first to lose its leaves in autumn.

The seeds are clumps of winged keys. The pale dense timber makes good firewood and is also used for hurley sticks, snooker cues and furniture.
