Common Ash

Fraxinus excelsior

The common ash is a majestic native tree that has shaped the Irish landscape for centuries. It is a vital component of our natural and cultural heritage, and its loss to ash dieback represents a profound tragedy.

Characteristics

Ash trees are known for their tall, graceful stature, often reaching heights of 35 meters. They have a distinctive domed canopy and smooth, pale grey bark that fissures with age. The leaves are pinnately compound, with 9-13 toothed leaflets. In winter, the smooth twigs with their characteristic black, velvety buds are a key identification feature.

Ecological Importance

Ash is a keystone species in Irish ecosystems, supporting a vast array of biodiversity. It is estimated that over 950 species are associated with ash, including 45 that are entirely dependent on it for their survival. The tree's open canopy allows sunlight to reach the woodland floor, fostering a rich ground flora.

Its leaves provide food for a variety of insects, which in turn support birds and other predators. The bark provides a habitat for lichens and mosses, and the seeds are a food source for birds and small mammals. The loss of ash trees would trigger an extinction cascade, affecting countless species across multiple trophic levels.

Cultural Significance

The ash tree is deeply embedded in Irish mythology and folklore. It was considered one of the three sacred trees of Ireland, and was often planted near holy wells. In Celtic mythology, the ash was associated with healing and protection, and was believed to have magical properties.

Ash wood, known for its strength and flexibility, has been used for centuries to make hurleys, the traditional Irish sporting equipment used in the game of hurling. The wood is also prized for furniture making, tool handles, and construction. The loss of the ash tree is not just an ecological disaster, but also a significant blow to our cultural identity and heritage.

"Of the five sacred trees of Ireland described in myth and legend, three of them were ash. These five trees were believed to mark the centre of the five provinces of Ireland."

Traditional Uses
  • Hurleys: The traditional Irish sporting equipment, requiring strong yet flexible wood
  • Furniture: Prized for its attractive grain and durability
  • Tool handles: Valued for strength and shock absorption
  • Construction: Used in building and joinery for centuries
  • Firewood: Burns well even when green, historically important fuel source
